oilfield term kelly hose free sample
Flexible drilling rubber hoses play an important role in petroleum extraction. They should suffer high operating pressure, extreme operating temperature, abrasion and other inferior elements. Our special compounded synthetic rubber has been proven an effective and economical way to reject these problems. All our oilfield drill hoses are manufactured as API 7K or other related specifications.
Steel cable reinforcement loads most working pressure up to 15,000psi. The wires are usually zinc-plating or copper platting to improve steel wire resistant against rust and corrosion. Due to the thick reinforcement, the hoses should be handled or stored in correct way to avoid kicking or crushing. They will substantially decrease their rated operating pressure.
Rotary hose, Kelly hose, cement hose, mud hose, jumper hose and vibrator hose and choke & kill hoses are the most popular oilfield rubber hoses. They convey high-pressure drilling fluid from one place to another. Many end fittings are provided to satisfy different applications. Most end fittings are made according to API standards. Special order is also available.
The space around a pipe in a well bore, the outer wall of which may be the wall of either the bore hole or the casing; sometimes termed the annular space.†
A heavy, flanged steel fitting connected to the first string of casing. It provides a housing for slips and packing assemblies, allows suspension of intermediate and production strings of casing, and supplies the means for the annulus to be sealed off. Also called a spool.†
A device fitted to the rotary table through which the kelly passes. It is the means by which the torque of the rotary table is transmitted to the kelly and to the drill stem. Also called the drive bushing.†
A hole in the rig floor 30 to 35 feet deep, lined with casing that projects above the floor. The kelly is placed in the rathole when hoisting operations are in progress.†
The hose on a rotary drilling rig that conducts the drilling fluid from the mud pump and standpipe to the swivel and kelly; also called the mud hose or the kelly hose.†
A vertical pipe rising along the side of the derrick or mast. It joins the discharge line leading from the mud pump to the rotary hose and through which mud is pumped going into the hole.†
A rotary tool that is hung from the rotary hook and traveling block to suspend and permit free rotation of the drill stem. It also provides a connection for the rotary hose and a passageway for the flow of drilling fluid into the drill stem.†
The top drive rotates the drill string end bit without the use of a kelly and rotary table. The top drive is operated from a control console on the rig floor.†
n: the recording of the natural or induced radioactive characteristics of subsurface formations. A radioactivity log, also known as a radiation log or a nuclear log, normally consists of two recorded curves: a gamma ray curve and a neutron curve. Both help to determine the types of rocks in the formation and the types of fluids contained in the rocks.
n: a subsurface, porous, permeable or naturally fractured rock body in which oil or gas are stored. Most reservoir rocks are limestones, dolomites, sandstones, or a combination of these. The four basic types of hydrocarbon reservoirs are oil, volatile oil, dry gas, and gas condensate. An oil reservoir generally contains three fluids—gas, oil, and water—with oil the dominant product. In the typical oil reservoir, these fluids become vertically segregated because of their different densities. Gas, the lightest, occupies the upper part of the reservoir rocks; water, the lower part; and oil, the intermediate section. In addition to its occurrence as a cap or in solution, gas may accumulate independently of the oil; if so, the reservoir is called a gas reservoir. Associated with the gas, in most instances, are salt water and some oil. Volatile oil reservoirs are exceptional in that during early production they are mostly productive of light oil plus gas, but, as depletion occurs, production can become almost totally completely gas. Volatile oils are usually good candidates for pressure maintenance, which can result in increased reserves. In the typical dry gas reservoir natural gas exists only as a gas and production is only gas plus fresh water that condenses from the flow stream reservoir. In a gas condensate reservoir, the hydrocarbons may exist as a gas, but, when brought to the surface, some of the heavier hydrocarbons condense and become a liquid.
n: the average pressure within the reservoir at any given time. Determination of this value is best made by bottomhole pressure measurements with adequate shut-in time. If a shut-in period long enough for the reservoir pressure to stabilize is impractical, then various techniques of analysis by pressure buildup or drawdown tests are available to determine static reservoir pressure.
n: the machine used to impart rotational power to the drill stem while permitting vertical movement of the pipe for rotary drilling. Modern rotary machines have a special component, the rotary or master bushing, to turn the kelly bushing, which permits vertical movement of the kelly while the stem is turning.
n: a worker on a drilling or workover rig, subordinate to the driller, whose primary work station is on the rig floor. Sometimes called floorhand, floorman, rig crew member, or roughneck.
n: a length of pipe whose bottom edge is serrated or dressed with a hard cutting material and that is run into the wellbore around the outside of stuck casing, pipe, or tubing to mill away the obstruction.
A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table. This bushing is rotated via the rotary table and thus the pipe and the attached drill string turn while the polygonal pipe is free to slide vertically in the bushing as the bit digs the well deeper. When drilling, the drill bit is attached at the end of the drill string and thus the kelly drive provides the means to turn the bit (assuming that a downhole motor is not being used).
The kelly is the polygonal tubing and the kelly bushing is the mechanical device that turns the kelly when rotated by the rotary table. Together they are referred to as a kelly drive. The upper end of the kelly is screwed into the swivel, using a left-hand thread to preclude loosening from the right-hand torque applied below. The kelly typically is about 10 ft (3 m) longer than the drill pipe segments, thus leaving a portion of newly drilled hole open below the bit after a new length of pipe has been added ("making a connection") and the drill string has been lowered until the kelly bushing engages again in the rotary table.
The kelly hose is the flexible, high-pressure hose connected from the standpipe to a gooseneck pipe on a swivel above the kelly and allows the free vertical movement of the kelly while facilitating the flow of the drilling fluid down the drill string. It generally is of steel-reinforced rubber construction but also assemblies of Chiksan steel pipe and swivels are used.
The kelly is below the swivel. It is a pipe with either four or six flat sides. A rotary bushing fits around the flat sides to provide the torque needed to turn the kelly and the drill string. Rollers in the bushing permit the kelly free movement vertically while rotating. Since kelly threads would be difficult to replace, normally the lower end of the kelly has saver sub — or a short piece of pipe — that can be refurbished more cheaply than the kelly. Usually, a ball valve, called the lower kelly cock, is positioned between the kelly and the kelly saver sub. This valve is used for well control if the surface pressure becomes too high for the rotary hose or surface conditions.
According to the ″Dictionary of Petroleum Exploration, Drilling and Production″, ″[The] kelly was named after Michael J. (King) Kelly, a Chicago baseball player (1880-1887) who was known for his base running and long slides.″
The complexities of the oil and gas industry can make keeping up with all the terms and definitions related to drilling difficult. To simplify things, we’ve compiled a glossary of the most important terms related to drilling and to the oil and gas industry.
A test of oil mud to determine if the aniline point temperature (aninline point) of the oil will damage elastomers (rubber compounds). The aniline point corresponds to the amount and type of hydrocarbons found in an oil sample, so a low aniline point indicates higher aromatics, and vice versa.
Also known as “As Is, Where Is” and “In Its Present Condition”, “As Is” states there are no guarantees about the condition or usage of the property. The buyer is responsible for determining its condition and use cases.
Paid to the lessor by the lessee, this consideration extends the oil and gas lease terms when there is no operations or production. The payment typically gives the lessee another year, however, if no payment is made and operations cease, the lease is considered abandoned.
Also called a dip meter or dip log, this surveying method determines the direction and angle of a formation dip in relation to the borehole to provide geological structure of the formation.
Transmits fluid and rotational power from the kelly bushing to the drilling collar. As the name suggests, the drill string is a column, or string, with attached tool joints.
Used by geologists to determine the nature of rocks, a special tool is used in an uncased hole that outputs electrical current into the rock and records the rock’s resistance.
A long hollow steel bar that’s used to connect the upper end of a drill string. Kelly bushing is a sleeve in the rotary table that allows the Kelly to freely move up and down during drilling. Kelly bushing also plays a part in the measurement of well depth, as well depth is measured from the Kelly bushing, down to the bottom of the well.
A contract between the mineral owner and the company interested in drilling that gives the interested company rights to explore and produce oil and gas for a specified term. The lease is usually given for royalty payments in return.
The machine used to drive rotational power to the drill stem while still allowing vertical movement of the pipe for rotary drilling. Most moden rotary machines have a rotary or master brushing used to turn the kelly bushing, which then allows vertical movement of the kelly while the stem is turning.
CARRIED INTEREST– A term used by independent oil operators who are selling interests in a well they propose to drill. The operator offers to drill the well to casing point if the industry partners will “Carry” or pay his share of the cost. SeeONE-THIRD FOR A QUARTER.
FLANGE-UP– Oil-field slang meaning to finish the job. Derived from work with pipe having flanges (rims) on the ends; this pipe is bolted together at those flanges; the pipe can carry liquids once it is “Flanged Up.”
INTERMEDIATE STRING– SeeCasing. There may be several strings of casing in a well, one inside another. The first casing put in a well is called Surface Pipe which is cemented into place and serves to shut out and protect shallow water formations and also as a foundation or anchor for all subsequent drilling activity. Extremely deep wells will often have an “intermediate string” cemented in place to protect and preserve the well bore as the remaining hole is drilled and completed.
JACK–KNIFE RIG– A mast-type derrick whose supporting legs are hinged at the base. When the rig is to be moved, it is lowered or laid down intact and transported by truck.
KELLY– The first and sturdiest joint of the drill column; a thick-walled, hollow steel forging with two flat sides and two rounded sides. When fitted into the square hole in the rotary table will rotate the kelly joint and thence the drill column and drill bit. Attached to the top of the kelly is the swivel andmud hose.
KELLY HOSE or MUD HOSE –This is a flexible, steel-reinforced, rubber hose connecting the mud pump with the swivel and kelly joint on the drilling rig. Mud is pumped through the mud hose to the swivel and down through the kelly joint and drill pipe to the drill bit at the bottom of the hole.
ONE-THIRD FOR A QUARTER– A term used by independent oil operators who are selling interests in a well they propose to drill. An industry partner who agrees to the one-third for a quarter deal will pay one-third of the cost of the well to some point and receive one-fourth of the well’s net production. When the operator sells three of these one-third for a quarter interests, his industry partners will have paid the cost of drilling the well to casing point.
RAT HOLE –A slanted hole drilled near the well’s bore hole to hold theKellyjoint when not in use. The kelly is unscrewed from the drill string and lowered into the rat hole as a pistol into a scabbard.
RIG DOWN– A term meaning to disassemble or take apart after operations are complete. This term applies to any complex operation where multiple parts were assembled for an activity.
RIG UP– A term meaning to assemble or put together in preparation to go into operation. This term applies to any complex operation where multiple parts are assembled for an activity.
STEP-OUT WELL – a.k.a. Offset Well– A well drilled adjacent to a proven well but located in an unproven area; a well located a “step out” from proven territory in an effort to determine the boundaries of a producing formation. SeeDevelopment Drilling.
TURNKEY CONTRACT– A contract to drill, complete and equip an oil or gas well for a set, predetermined price. The turnkey format is designed to limit the liability of an industry partner to the amount of their capital contribution for drilling and completion.
Accredited Investor - A person or institution deemed capable of understanding and affording the financial risks associated with the acquisition of unregistered securities. The federal securities laws define the term accredited investor in Rule 501 of Regulation D as:a bank, insurance company, registered investment company, business development company, or small business investment company;
a natural person with income exceeding $200,000 in each of the two most recent years or joint income with a spouse exceeding $300,000 for those years and a reasonable expectation of the same income level in the current year; or
Anticline - A geological term describing a fold in the earth"s surface with strata sloping downward on both sides from a common crest. Anticlines frequently have surface manifestations like hills, knobs, and ridges. At least 80 percent of the world"s oil and gas has been found in anticlines.
Completion - A general term referring to all activities necessary to put a well on production after it has been drilled to casing point. The completion phase of operations generally includes cleaning out the well bore, setting the casing and tubing into the hole, adding surface equipment (pumps, tanks, meters) and perforating the casing so that oil or gas can flow into the well and be brought to surface. Once a well is completed, it is ready to produce oil or gas.
Conditions of Sale - The legal terms that govern the conduct of an auction, including acceptable methods of payment, terms, buyer"s premiums, possession, reserves and any other limiting factors of an auction. They are usually included in published advertisements or announced by the auctioneer prior to the start of the auction.
Dipmeter Survey - An oil well surveying method that determines the direction and angle of formation dip in relation to the borehole. It records data that permit computation of both the amount and direction of formation dip relative to the axis of the hole and thus provides information about the geologic structure of the formation. It is also called a dipmeter log or dip log.
Down-dip - A term used in a hydrocarbon reservoir that is not flat, i.e., a dipping formation. In such a formation, oil is found down-dip from the gas.
Drill String - The column, or string, of drill pipe with attached tool joints that transmits fluid and rotational power from the kelly bushing to the drill collars and the bit. Often, the term is loosely applied to include both drill pipe and drill collars.
Electric Log - An electrical survey made on uncased holes. A special tool is lowered into the hole which ejects an electrical current into the rock and records its resistance to the current. The data from the survey is used by the geologist to determine the nature of the rock and its contents.
Formation- A geological term that describes a succession of strata similar enough to form a distinctive geological unit useful for mapping or description.
Gas Lift - A method of secondary recovery similar to gas injection, except that the injection well and the production well are both the same well. Dry natural gas is pumped down through the space between the casing and the production tubing, and into the reservoir. Gas dissolves into the oil increasing the oil"s ability to flow, and reservoir pressure is increased around the well. The procedure of injecting gas and then flowing the oil-and-gas mixture is carried on intermittently. The gas is separated from the mixture at the surface, where it is stored for re-injection.
Joint Operating Agreement (JOA)- A detailed written agreement between the working interest owners of a property which specifies the terms according to which that property shall be developed.
Kelly Bushing (KB) - Part of the drilling rig, the Kelly is a long hollow steel bar that connects to the upper most end of the drill string. it is square or hexagonal in cross-section. The Kelly bushing is a "sleeve" in the rotary table through which the Kelly can freely move up and down during drilling. The depth to a particular zone for a well is generally measured from the Kelly bushing, which can be anywhere from about 5 to 50 feet above ground level (dependent on the type and size of drilling rig used).
Lease- A contract by which the owner of the mineral rights to a property conveys to another, the exclusive right to explore for and develop minerals on the property, for a specified period of time. The conveying party is "lessor"; the mineral rights owner. The recipient is "lessee". The terms of the lease are typically negotiated between company, and the owner of the mineral rights.
Listing Agreement - A contract executed by the auctioneer and the seller which authorizes the auctioneer to conduct the auction and sets out the terms of the agreement and the rights and responsibilities of each party.
Midstream - A term sometimes used to refer to those industry activities that fall between exploration and production (upstream) and refining and marketing (downstream). The term is most often applied to pipeline transportation of crude oil and natural gas.
Non-Accredited Investors - Persons or entities who do not satisfy one or more of the alternative definitions of the term "Accredited Investor" and who, by virtue of their financial resources acumen, satisfy the suitability standards imposed by Rule 506 of Regulation D and otherwise meet the financial investment standards therein required.
Offering Memorandum - A legal document provided to potential investors in a venture (such as an oil and gas limited partnership, Joint Venture), describing the terms under which the investment is offered.
Porosity - A ratio between the volume of the pore space in reservoir rock and the total bulk volume of the rock. The pore space determines the amount of space available for storage of fluids. These spaces or pores are where oil and gas accumulate; therefore, a formation containing a high percentage of porosity can contain more hydrocarbons.
Roughneck- One of the two or three field-hands on the derrick floor during drilling operations, whose job revolves around breaking out the drill pipe, making connections, and stacking drill pipe. It is a tough, physically demanding, and very dangerous job.
Sealed Bid- A method of sale utilized where confidential bids are submitted to be opened at a predetermined place and time. Not a true auction in that it does not allow for reaction from the competitive market place.
Secondary Recovery - A broad term encompassing any method of extracting oil from a reservoir after a well or field has exhausted its primary production. After primary recovery operations have taken their course, various operations may be taken to increase the amount of oil by normal methods of flowing and pumping. The second stage to increase production is by addressing the condition of the reservoir. Typical operation may involve forcing gas ("gas injection"), or water ("water flooding") into the reservoir. This re-pressurizes the reservoir, which allows recovery of more oil than would be possible from primary recovery.
Sedimentary Rock- Rock that is naturally formed from fragments of other rocks by compression. Sedimentary rocks are important in terms of petroleum because sandstone and limestone are often reservoir rock. Rock is generally classified in one of three categories; sedimentary, igneous or metamorphic.
Spacing- The distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres, e.g., 40-acre spacing, and is often established by state regulatory agencies.
Stimulation- The term used for several processes to enlarge old channels, or create new ones, in the producing formation of a well designed to enhance production. Examples include acidizing and fracturing.
Top Lease- A conditional lease that may be granted by the mineral-rights owner of a property while a pre-existing recorded lease of that property is nearing expiration, but nonetheless is still in effect. The top lease goes into effect only if and when the existing lease expires (or is terminated).
Unit- A fixed measure of investment into a Joint Venture, the number of units offered is determined by each exploration company and project. For example, a subscription agreement may offer 20 units at $25,000 per unit.
A large-diameter (3- to 5-in inside diameter), high-pressure flexible line used to connect the standpipe to the swivel. This flexible piping arrangement permits the kelly (and, in turn, the drillstring and bit) to be raised or lowered while drilling fluid is pumped through the drillstring. The simultaneous lowering of the drillstring while pumping fluid is critical to the drilling operation.
