A Base Beam is used on a workover rig for stabilization. They are used in place of ground anchors. Guice Base Beams set the standard for internal guying solutions. They are designed to meet requirements of API RP 4G 14.3. Our beams are proven to decrease rig up and rig down times and will endure the rigorous stresses of the oilfield. We manufacture in-house at GEI Welding. Each beam comes with an assigned serial number to prove it’s a Guice Base Beam.

Guice Base Beams come in 3 standard widths, 2 different variations and can be customized and painted to your specific needs. Base Beam certification is free when manufactured by GEI Welding!

Their exceptional mobility, stability, and ease of operation are the outcome of our extensive experience in the design and production of mobile drilling rigs.

Belonging to the same family, Sovonex™ service rigs comprise many of the technological advantages that result in smooth operation and make the life of our customers’ easier:

Wide selection: At our production facility in China we design and develop workover rigs for service depths ranging from 1,600 m to 8,500 m (5,250 ft-27,900 ft), and workover depths from 2,000 m to 9,000 m (6,600 ft-30,000 ft) for 2 7/8” DP.

Full API coverage: The different components of our well-servicing rigs are manufactured to the following API standards:Steel structures, such as the mast: API Spec 4F

Highly maneuverable : Sovonex™ mobile drilling rigs and self-propelled workover rigs possess excellent driving properties in the desert, mountain, and other impassable terrains.

Reduced NPT: The mast is erected hydraulically to reduce time for rig up and increase safety. Likewise, all rig components have been designed to allow for fast assembly and disassembly.

With every service rig, we send technical staff to our customer to provide first-hand technical support. The engineer responsible for the rig design is always part of the service crew.

Workover Rig is available for both onshore as well as offshore Workover purposes at affordable prices. There are a number of companies that manufacture the Workover Rig as well as Rig packages that are required for different kinds of drilling jobs and meet the standards that have been set by the American Petroleum Institute or the API. The Rig packages are shipped worldwide. The rigs are included other than the simple Workover and they include the following:

Workover Rig is known as the Workover the different types of rigs include the offshore and onshore Rig that range from 150 horsepower to 1000 horsepower. Workover rigs have a surface depth that is equipped with diesel engines and transmissions and is available from 8000 ft to 30000 ft. Workover rigs contain a full line of drilling packages. Rig takes into account the skid mounted drilling rigs and the ones that are trailer mounted. Workover skid mounted drilling rigs incorporate the diesel-electric AC/VFD or the DC/SCR drive rigs, mechanical drive rigs and the combination drive Rig that ranges from 1000 horsepower to 6000 horsepower; while the trailer mounted Rig ranges from 450 horsepower to 1000 horsepower.

A lot of Workover Rig uses the double telescopic mast with the help of a single mast and is operated by wide wheel base axels, high strength steel beam, low cross section tires, dual pipeline brakes as well as hydraulic assist steering for the Workover. Rig mast is a double section type and uses a telescopic mast for dual safety protection. The gear shift and throttle of the engine can be remote controlled.

Workover types of Rig are available in the form of the single drum as well as the double drum. The groove ensures the alignment of in place as well as for long life. The optional Workover accessories for the auxiliary brakes include air thrust disc type clutch, brakes for the braking of the main drum, forced water circulating cooling with the brake rims as well as the optional brakes. Workover rigs are centrally controlled with electricity. The other kinds of drilling equipment include drilling equipment, triplex mud pumps, well control equipment; solids control equipment, oil control tubular goods and quality equipment. Work over rigs run casing tools and clean outs inside and outside a hole already drilled.

n: a wireline used on drilling rigs and well-servicing rigs to operate a swab or bailer, to retrieve cores or to run logging devices. It is usually 9/16 of an inch (14 millimeters) in diameter and several thousand feet or meters long.

n: 1. the use of water-flooding or gas injection to maintain formation pressure during primary production and to reduce the rate of decline of the original reservoir drive. 2. water-flooding of a depleted reservoir. 3. the first improved recovery method of any type applied to a reservoir to produce oil not recoverable by primary recovery methods. See primary recovery.

v: to place stands of drill pipe and drill collars in a vertical position to one side of the rotary table in the derrick or mast of a drilling or workover rig. Compare lay down pipe.

n: 1. the flat portion machined on the base of the bit shank that meets the shoulder of the drill collar and serves to form a pressure-tight seal between the bit and the drill collar. 2. the portion of the box end or the pin end of a tool joint; the two shoulders meet when the tool joint is connected and form a pressure-tight seal.

n: a procedure to ensure that the drilling line wears evenly throughout its life. After a specified number of ton-miles (megajoules) of use, the line is slipped-for example, the traveling block is suspended in the derrick or propped on the rig floor so that it cannot move, the deadline anchor bolts are loosened, and the drilling line is spooled onto the drawworks drum. Enough line is slipped to change the major points of wear on the line, such as where it passes through the sheaves. To prevent excess line from accumulating on the drawworks drum, the worn line is cut off and discarded.

n: a set of gears installed between a prime mover and the equipment it drives to reduce the running speed. For example, on a beam pumping unit, the engine may run at a speed of 600 revolutions per minute, but the pumping unit it drives may need to operate at 20 strokes per minute. The speed reducer makes it possible to obtain the correct pump speed.

n: a measurement of the electrical currents that occur in the wellbore when fluids of different salinities are in contact. The SP curve is usually recorded in holes drilled with freshwater-base drilling fluids. It is one of the curves on an electric well log. Also called self-potential curve.

n: the connected joints of pipe racked in the derrick or mast when making a trip. On a rig, the usual stand is about 90 feet (about 27 meters) long (three lengths of drill pipe screwed together).

n: a special steel pumping rod. Several rods screwed together make up the mechanical link from the beam pumping unit on the surface to the sucker rod pump at the bottom of a well. Sucker rods are threaded on each end and manufactured to dimension standards and metal specifications set by the petroleum industry. Lengths are 25 or 30 feet (7.6 or 9.1 meters); diameter varies from 1/2 to 1 1/8 inches (12 to 30 millimeters). There is also a continuous sucker rod (trade name: Corod™).

n: a method of artificial lift in which a subsurface pump located at or near the bottom of the well and connected to a string of sucker rods is used to lift the well fluid to the surface. The weight of the rod string and fluid is counterbalanced by weights attached to a reciprocating beam or to the crank member of a beam pumping unit or by air pressure in a cylinder attached to the beam.

n: a solid cylindrical tool pointed at the bottom and equipped with a tool joint at the top for connection with a jar. It is used to straighten damaged or collapsed casing or tubing and drive it back to its original shape. v: to reduce the diameter of a rod, a tube, or a fitting by forging, hammering, or other method.

The grid electricity workover rig can meet all kinds of workover operational requirements due to its safety, stability, and reliability as well as excellent technical performances. The wellsite is now completely free from exhausted gas/oil emissions, and well site noise has also been greatly reduced. We can make a new contribution to save energy in oilfields by using this kind of environmentally-friendly workover rig.

Our company founded in the Yellow River delta (Shengli Oil Field, the second large oil field in China)--- Dongying City, Shandong Province. It engages into the designing, developing, testing, manufacturing, repairing, and drilling service. Its business covers drilling rig, workover rig, solids control equipment, drilling rig supporting and drilling strings and other equipments related with petroleum.
