Continuous Mandrel SCP assemblies are designed with packer elements in 4 Foot (1.22m) and 10 Foot (3.05m). SAGA Casing Packer elements soundly conform to irregular or washed-out hole diameters. Steel reinforcement slats are used within the elements to ensure that the SCP self-centers itself in vertical, deviated, or horizontal wellbores.
Tools are available in Standard and Special clearance models. Standard clearance tools are used where higher differential pressures are encountered across the packer element. Special clearance tools are used for applications where restricted hole diameters may occur. Continuous Mandrel SCP assemblies are typically inflated with cement displacement fluid. An integral screen prevents coarse particles from entering the valve system. The valves are designed with high quality materials, which will not erode when abrasive materials are pumped through the system. SCP valve system provides positive closing, after the element has been fully inflated to pre-determined pressure. After the shear valve has shifted to the final closed position, a mechanical locking device ensures that no further movement will occur.
SCP inflatable elements are available with Standard and Advanced elastomer compounds. Standard elastomer compounds may be used for temperatures up to 240° F (115°C). Advanced elastomer compounds are made available for applications in which temperatures reach up to 350° F (180° C).
OGSI’s line of Lancaster production chokes offers unparalleled features and options. The operating torque is over 90% less than typical commodity style designs. Thus, the ease with which this equipment may be automated is without equal. With options like having no elastomers in direct contact with well bore fluids together with metallic bonnet seals, neither safety or performance has been compromised. A stainless steel micrometer style position indicator provides for precise readout of the orifice size. Although not a requirement of API 6A, It remains on the choke even when mounting rotary type actuators.
With only 27 lb.-ft. of torque required for closing the stem against 15,000 psig downstream of the orifice, a small 17-pound (24 vDC) electric actuator (drawing 2.6 amps. at these conditions) is all that is required for automation. The unit may be operated using solar power and is easily removed while the choke is in service and under pressure. The choke is available in needle, cage, multi-stage cage, positive, and adjustable/ positive style trims. Regardless of the adjustable trim style, any type of actuator may be used with our standard components. Our choke and retrofit kits have been operating successfully offshore in the Gulf of Mexico since 1995.
Unlike so many others, the Lancaster production choke is NOT just another copy, clone, or modification of a commodity choke line, it is the next generation of choke design. Each individual component has been designed to maximize unimaginable product interchangeability, metallurgy, performance, safety, and automation. It is the first truly low torque design where API 6A PR2 requirements and automation were not an afterthought.
In a wellhead application, the choke should be the last valve to open and the first valve to close. No choke is easier to operate than this one. Whether you choose to automate or not, we recommend that you insist on installing a choke that operates easily, around the clock, at the working pressure stamped on the body. Install our user-friendly choke to save wear and tear on your gate valves and improve the overall safety of your well site operations.
Utilize our needle style trim to clean up or test your well prior to connecting the flow line. Then, if conditions dictate, install one of our cage trims to reduce noise and possible flashing or cavitation which may be encountered when producing water or condensate at high pressure drops along with the gas phase.
When desired, the actuator may be configured to fail in place, fail open, or fail closed. With the optional back-up power supply, the unit may be configured to fail closed on loss of power or command signal even in the event of a power failure. Weight of the 24 vDC actuator is a mere 23 pounds (10.43 kg) including the mounting kit.
Lancaster Flow Automation has the personnel, products, equipment, tools, software, and imagination to take care of your flow control.
