Most InSol treatments are custom designed. Cutting-edge tests with the problem oil and/or field deposits are performed at KostaTech's state-of-the-art asphaltene/wax laboratory facilities located at the company's headquarters in Stafford, Texas (a suburb of Houston). The cost for the above tests is generally born by KostaTech. InSol is suitable for most organic deposition problems. Some examples are discussed briefly below.
Formation
Damage (click here):
Properly designed InSol squeeze treatments can be used to remove existing organic scale from the near-well-bore formation. Similar squeeze treatments may be used for inhibition purposes to prolong the time between remedial treatments. In offshore and remote Arctic operations eliminating one or two squeeze remedial treatments per year by replacing a synthetic chemical with the natural and more effective InSol translates into considerable savings for the operator.
Tubings and
Flowlines (click here):
InSol may be used both as inhibitor and as remedial solvent/surfactant. Proper tests need to be made with the oil to determine whether it is preferable to inhibit or remedy an organic deposition problem. Also, in many cases, InSol is customized to a particular problem. If a deposit from the field is available, InSol/deposit tests may be made to customize InSol to the problem. InSol is a powerful solvent/dispersant for cleaning sub-sea flowlines plugging up from wax deposits.
Production
Facilities (click here):
InSol injection in the tubing and flowlines will most likely protect the production facilities from organic deposition. Hence, no additional InSol injection in the facilities is necessary.
Storage
Facilities (click here):
A portion of the re-suspended organic particles are expected to settle again in the storage facilities. Periodic batch treatments of the storage facilities can be designed to eliminate the accumulation of organic particles.
