BOP Cans and wellhead hangers
Need to have well control capability during an ESP Drill Stem Test?
A Drill Stem Test (DST) is a procedure to determine the productive capacity of a hydrocarbon reservoir. DSTs are typically performed on exploration wells, and are often the key to determining whether a well has found a commercial hydrocarbon reservoir. Pressure of the reservoir is often at its highest point during a DST, and the reservoir fluids may contain hydrogen sulfide, so these tests can carry considerable risk for rig personnel. Well control is of utmost importance.
Carrying out a DST with an Electrical Submersible Pump requires a BOP can. The BOP can provides a means of sealing the ESP power cable with a penetrator to create a pressure barrier, and also provides a cylindrical housing to close and seal the Blow Out Preventer (BOP) pipe rams around the BOP Can to complete the pressure barrier with the well annulus.
Flowell’s BOP Can is available in 10-3/4”, 9-5/8” and 7” sizes to suit the BOP pipe rams. Where the DST string is required to be landed out in the wellhead, an adjustable hanger is available to hang off and space out the BOP Can, and the landing string as required.
