We are Supplier and Exporter of Perforated Pup Joints in UAE. It is usually installed between the bottom of two nipples of a completion. It allows unrestricted fluid or gas flow, which increases the accuracy and reliability of acquired downhole production data.

We supply all sizes, grades, and thread profiles to meet custom requirements. The perforated pup joints are sometimes also known as the perforated production tube. All our products have passed the ISO certification and API certifications. Our products are tested numerous times under technical guidance and are made from the best quality material.

A pup joint is a casing or tubing of length shorter than Range 1 with the same thread connection, used to adjust the length of tubular strings to its exact requirement.

Pup Joints are manufactured from AISI 4145H or 4140H-modified alloy, heat-treated to a Brinell Hardness range of 285-341 with a Charpy “V” notch minimum impact strength of 40 ft/lb at 70° F and one inch below the surface. Pup Joints are heat-treated to 110,000 PSI minimum yield. All connections are phosphate coated to impede galling during initial make-up.

Integral Pup Joints dedicated to Sour Service applications are available. PJ -110 PUP S are Sour Service Pup Joint using ASCOWELL C material providing improved resistance to Sulfide Stress Cracking with high yield strength.

A pup joint is Casing, Pipe or Tubing shorter in length than a standard tubular string. This allows for the adjustment and installation of tools and various tubular components when placement downhole is critical for a specific project. A Spacer Pipe is another reference used to identify pup joints. Pup joint features consist of connections, lengths, weights and material grade.

Crossover pup joints are manufactured from seamless mechanical tube. As with all Crossover products, each piece is marked with a distinctive job number and heat number that is fully traceable. A complete range of sizes (1" to 4.5"), weights (standard or heavy wall), and grades (J-55, N-80, L-80, and P-110) are commonly available from stock in 2", 3", 4", 6", 10", and 12" lengths. Lengths up to 20" are available upon request.

Seamless pup joints with premium connections are available in API and exotic alloy grades. Premium ends are threaded by the manufacturer or authorized licensee.

Available with standard or special perforation spacings. Each joint has four rows of ⅜ inch holes drilled longitudinally along the tube. Optional patterns, hole size, and lengths furnished upon request.

A blast joint is shorter in length than standard tubular joint. Built with a heavy wall pipe it is incorporated in the production string to facilitate production across any perforated interval and zone. Blast Joints are manufactured to the following specs connections, lengths, weights and material grade.

Crossover Blast Joints are heavy wall pin by box connectors used in tubing strings and are designed to minimize the effect of external erosive action caused by production fluids. Blast joints are located opposite the location of perforations in the production casing or just below the tubing hanger in sand frac designs. Crossover blast joints are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 10" and 20". Both API and Premium threads are available.

Crossover Coarse Thread Tubing Safety Joint provides for emergency recovery of the major portion of the tubing string should it become necessary to abandon the equipment below. Precision left-hand threads facilitate the release of the joint by right-hand tubing rotation. Equipment requiring right-hand rotation should not be used below the Safety joint.

Crossover Straight-Pull/Shear-Out Safety Joint is used between packers in dual and triple completions and in selective completions using Hydrostatic Single-String Packers. It is also used when rotational releasing is not desired. When ran above the upper packer in a single-string completion, however, the shear value should be adjusted to compensate for any hydraulic conditions that exist when the string is landed, or that are created by well treating operations. They are available in keyed and non-keyed configurations.

Crossover rotary shoes are manufactured from specially tempered steel to provide the ultimate in toughness and durability. They are used to cut a clearance between the fish and the wall of the well bore. Each shoe is tailored to fit a particular downhole need and normally is run on the bottom of one or more joints of washover pipe. Shoe design is dictated by whether it cuts on the bottom, on the OD, on the ID, or any combination of these. When hole sizes permit, additional clearances can be cut using side ribs, thus providing greater circulation.

Swivel Joints and Blast Saves are our widely recognized premium solutions for ensuring the best performance, endurance and quality in intelligent completion design. With dual metal-to-metal seals, they are available in a range of sizes, metallurgies and steel grades, and their upper and lower ends can be customized for many of our premium connections.

Our Swivel Joint premium connectors are designed to solve alignment problems during dual completion or intelligent completion installations. Furthermore, our Swivel Joints Torque Transmission (TT) can withstand torque in excess of the maximum make-up torque of premium connections.

Our Blast Saves are designed to protect control lines from impact or erosion generated by high pressure/high velocity wellbore fluids and particles, or when the control lines are run alongside the production tubing, in front of the perforated wellbore area. Every Blast Save module has ability to automatically align the longitudinal slots when making up the string, while reaching the optimum make-up torque value.

In wells flowing large volumes, a restriction in the tubing such as a gauge hanger, could cause false pressure readings. Vibrations due to flow could also cause extensive damage to delicate gauges, therefore a perforated pup joint (approx. 10ft length) set above the bomb hanger nipple would allow flow to pass unrestricted over the gauges and hanger, thus giving a more accurate pressure/temperature recording within the

In the oil and gas drilling industry, the tubing pup joint is a critical component for the completion of a well. The pup joint allows the driller to change out the drill pipe without having to pull out the entire string of pipe from the well. This is a common practice, especially when drilling deep wells. Because of this, the tubing pup joint is one of the most important joints in any well.

Tubing pup joints are small-diameter tubing that is used in conjunction with casing to complete a well. The pup joint is run in the hole and cemented to the casing, and then the production tubing is run over it and attached. This arrangement allows for the use of smaller-diameter production tubing, which results in less pressure drop and improved production. The pup joint is usually located in the last few feet of the tubing string.

The oil and gas industry (like many others) has a lot of industry specific terminology. In many cases, this terminology is specific to the region and/or type of reserves being developed. AlphaTally is an auto-design tool producing the tallies describing the order of parts in the casing string. In this article, we will go into the basic principles and the nuances of the key parts of a casing string, particularly the key functionalities of casing joints, swellable packers, slotted/perforated liners and the ACP / stage tool. We hope this can provide insight into the workings of coals seam gas wells and the associated jargon for anyone who might be interested, regardless of background.

The physical makeup of the casing comprises of smaller pipe joints which are connected together as the casing is “ran” into the wellbore, prior to cementing. These joints are typically around 13m (40ft) for “full” joints, or can come in a variety of smaller sizes as “pup” joints. Joints are either manufactured with a male and female thread form or dual male thread forms, requiring the use of couplings to join them. The ends of a casing joint are defined by their associated thread form, defined as the pin end where the male thread form is and the box end where the female thread form is, as shown below.

Mechanically, these assemblies consist of the following parts, from shallowest depth set to deepest: ACP pup joint, float collar, stage tool, ACP. The functions of each of these parts within the respective role of the assembly is outside the scope of this article.

As the name suggests, slotted or pre-perforated liners are parts of the tubing string which are ran with holes already drilled into them. These holes allow for production of wellbore fluids. Traditionally, solid tubing was run down and small explosives were used to perforate the desired sections. However, this was found to be less suitable in coal seam gas developments, due to the efficiencies of installing a part that has already been perforated in the factory and the greater onus placed on surface area exposed . As a result, the majority of coal seam gas developments utilize pre-perforated completions (fracked completions are used where the coal permeability is not sufficiently high).

PUP JOINTS are a joint of pipe of non-standard length used to adjust the length of tubular strings to exact requirement. We provide both tubing (2 3/8” to 4”) and casing (4” to 13 3/8”) in all lengths. With our myriad of licenses (quality page) we are able to cut to length, thread and couple to meet specified needs. API casing and tubing pup joints are manufactured according to API Spec 5CT using prime API monogrammed, seamless oil country tubing. Premium pup joints are also available with premium connections and in API or exotic alloy grades.

MARKER JOINTS are a joint of tubing used in a workover or completion tubing string that serves as a position or depth indicator. In most cases, a marker joint is significantly shorter than other joints in the string so that it is easily noticeable.
