Trailer-mounted packages are designed and fabricated based on the client requirements as well as GOSCO’s own serial developed solutions. Trailer-mounted packages are used in oilfields accommodating required and necessary equipment on it.
Surface well test trailer package (SWT Package) or trailer mounted surface well test system is a special system of well test equipment designed to separate well fluids into two/three/four phases, then accurately measure behavior of each phase after separations.
Test Separator Skid is in the center of any well testing operation. Test separator separates well fluids into two/three/four phases. Each phase line consists of control valves, meters, ball valves and other components specified in the technical proposal. As the safety devices, two or three relief valves are installed on the separator vessel and inlet manifold (Note: confirm with GOSCO required quantity of relief valves and place of installation). High/Low- or High-Pressure Pilots are also can be used as additional safety measures (Note: confirm if pilots are included in the scope). Pressure Vessel is made either made of standard service or sour services construction steel depending on the client’s requirements. Pressure Vessel has multiple nozzles to connect level gauges, level controllers, pressure and temperature gauges, instruments and other parts specified in technical proposal and P&ID.
Emergency Shutdown System (ESD System) consists of multiple equipment and parts are important parts of safety measures during well testing and production. ESD system consists of ESD control panel, 5K/10K/15K Surface Safety Valve (SSV), High/Low- or High-Pressure pilots, Pneumatic SS Pipes, hydraulic hoses, emergency pushbuttons. ESD Control Panel provides hydraulic pressure to actuators or SSV and SSV of Flowhead. ESD Control Panel is equipped with oil tank, pneumatic lines, pneumatic-hydraulic pump or hand pump, gauges and other parts which is specified in technical proposal.
5K/10K/15K Choke manifold is 4-valve or 5-valve assembly, which includes one positive and one adjustable choke. Choke Manifold is designed to reduce flow (pressure) of well stream, protecting downstream equipment.
Data Header is special pipe with unions and ports, designed to monitor pressure, temperature, and allow operator to inject chemical to the well fluids.
Test pump is designed to provide necessary pressure to the surface well test equipment before starting operation. Confirm with GOSCO brand name or type of test pump required for your project.
Long trailers also accommodate lab and office cabin with all necessary instruments and means of convenient and safe operation. Utility equipment such as Diesel Generator and Air Compressor is also provided.
Trailer base is designed to handle payload of 20/30/40/50 tons. HC Petroleum Equipment purchases trailer base from reliable domestic supplier, then modifies it based on the in-house design and accommodate surface well test equipment and unitality equipment. Pipe rack can be added as additional features to carry flowline equipment for oilfield operations. Trailer is equipped with ex-proof lights, distribution panels, tools boxes and other additional features specified in technical proposal.
