Early Production Facility (EPF)

Early Production Facilities (EPFs) are designed using a fast-track modular approach, enabling operators to bring newly drilled wells online quickly and generate early revenue.

These systems allow simultaneous production and data acquisition, providing critical reservoir performance insights while maintaining continuous operation.

EPFs typically include separation, gas compression, water treatment, and storage systems, configured for rapid deployment and easy relocation.

Ideal for short- to medium-term field development, EPFs help reduce project risk, optimize capital expenditure, and validate reservoir potential before full-scale production facilities are commissioned.

Vertical Surge Tank

Al Shirawi standard well testing Surge Tank is a H2S service pressurized vessel designed for various volumes (50 – 100 BBL) with either single compartment or twin compartment. Another advantage of Al Shirawi designed Surge Tank is that the design allows for an option of having a 2” steam heating coil with inlet/outlet. The package is designed to offshore lifting standard DNV2.7-1 and CSC approved skid with crash frame for ease of rapid transportation to offshore or onshore worksites globally on container vessels.

Compliance:
Vessel : ASME Sec VIII , Div 1/ANSI B31.3, NACE MR0175, CE-PED ,NORSOK
Structure: DNV2.7 -1/EN-12079/CSC 1496

Steam Heat Exchanger/Indirect Water Bath Heater

Al Shirawi designed & developed various types of Steam Heat Exchangers and Water Bath Heaters for various pressure and temperature ratings. The package is designed to offshore lifting standard DNV2.7-1 and CSC approved skid with crash frame for ease of rapid transportation to offshore or onshore worksites globally on container vessels.

Compliance:
Vessel : ASME Sec VIII , Div 1/ANSI B31.3, NACE MR0175, CE-PED ,NORSOK
Structure : The standard 20 ft skid frame is designed to meet DNV2.7 -1 and CSC

Gauge Tanks

The atmospheric gauge tank is part of the standard equipment for well testing, it is used to measure low flow rates or to calibrate metering devices on the separate oil lines in a testing system. The tanks can also be used for temporarily storing oil. And hence can also be called temporary oil tanks. These tanks are skid mounted units or trailer mounted test units, have two compartments. As a transfer pump empties one compartment, the other starts getting filled.

Compliance:
Tank : NACE MR0175, CE-PED

Structure: DNV2.7 -1/EN-12079/CSC 1496

Twin trailer mounted packages

Trailer Mounted Packages are designed for mobile surface well testing, featuring a twin-trailer configuration that combines mobility, safety, and full operational capability in compliance with oil & gas field standards.

The Primary (Process) Trailer — Zone-rated — integrates all major process equipment including separators, surge tanks, pump skids, 10K/15K psi choke manifolds, and SSV manifolds, supported by Ex-D lighting, Emergency Shutdown (ESD), and Data Acquisition System (DAS) for safe and efficient field operations.

The Secondary (Utility) Trailer — Non-Zone-rated — includes a 20’ office container, diesel generator sets, utility/instrument air compressor package, diesel storage system, piping package, and flood lights, providing complete power and utility support to the process trailer.

Both trailers are 40-ton payload desert-application units, fully engineered for harsh environments, supplied ready to operate, and compliant with international health, safety, and performance standards for surface well testing applications.

Cost-Conscious Packages are engineered as single-trailer solutions to meet the needs of low-budget oilfield operations without compromising performance or safety.

The integrated design combines both process equipment and utility systems on a single trailer, significantly reducing capital cost, footprint, and mobilization time.

Each unit is equipped with essential components including separators, pump skids, 10K/15K psi choke manifolds, SSV, data header, lab container, generator, and compressor, providing a fully functional well testing setup.

These packages are optimized for cost efficiency, quick deployment, and ease of maintenance, making them ideal for short-term projects and remote field operations.
