Resources
We have been manufacturing perforating gun hardware and accessories since 1989 and currently have a total capacity of approximately 55,000 ft of production per month between our Dubai and Aberdeen plants. We manufacture wireline or tubing-conveyed perforating gun carriers from 111/16- to 10-in. OD in several locations around the world, along with required loading tubes, adapters, and other accessories. Where applicable, the guns meet requirements including API, NACE NPD, and EEUMA and are certified by a third-party certifying authority.
Perforating Guns
The Elmar™ Gun Shop, established in Aberdeen in 1989, manufactures perforating gun (TCP) equipment to clients’ own designs. It has the capacity to manufacture approximately 25,000 ft per month of perforating guns and works closely with customers in Europe, Russia, and the CIS, Africa.
Tubulars also has a presence in Dubai, where the team has been manufacturing TCP equipment since 2000. The department in Dubai has the capacity to manufacture approximately 20,000 ft per month, with sizes varying from 19/16 to 4½ in. and increasing to 7 in. with the addition of new machines.
- Manufacturing of tubing-conveyed perforating guns: 19/16, 2, 2½, 2⅞, 3⅜, 3½, 4½, 4⅝, 5¼, and 7 in.
- Assemblies include: Gun body, tube, and customer-specific hardware kits
Holing and slotting of casing
Elmar slotted and holed liners are manufactured on specially designed multi-spindled machines that assure a high level of machining accuracy while maintaining metallurgical properties through the continuous application of coolant during the cutting process. We can deburr pipes from 2⅜- to 12-in. OD and 50-ft length with a purpose-built deburring machine. This machine can remove swarf, rust, and grease. After deburring, the pipes are given a protective coating to prevent further rust. Slot widths of 0.012 to 0.25 in. in a variety of patterns can be accommodated with a range of slot lengths to suit the requirement. Holed casing can be produced with a variety of hole patterns and pitches and with diameters from 9.5 to 25 mm.
Wire-wrapped screens
We have been producing wire wrapped screens under license since 1995. We have the capacity to produce 150 joints per week with a range of base pipe sizes from 4 to 9⅝ in. At our facility in Westhill, Scotland, we have the capability to complete the whole screen assembly from machining of the base pipe, welding of components, and wrapping of wire through to complete inspection and assembly. Documents are maintained for customer assurance and full traceability of material and control procedures.
Tubular accessories
To complete your gun system, we manufacture a large range of connectors and hardware equipment. Typical connectors and TCP hardware components include swivel connector assemblies, adapters, tandem and crossover subs, firing head adapters, thread protectors, bull plugs, and side-mount assemblies. Our components are designed to suit all gun sizes.
