PIC scientists are challenged by Deepwater issues needing economic solutions that the “Big Box” integrated service providers cannot provide. The cost of even minor interventions can run into the millions of dollars. This means that treatments must be effective and long lasting. Continuous plugging of screens and perfs resulting from asphaltene onset pressures, fines migration, and profile modifications are common issues being successfully mitigated by PIC technology.
PIC has invented a gelled xylene containing soluble microfibers to achieve more comprehensive zonal coverage. This solution more than doubled the average hydrocarbon production and extended the life over previous xylene treatments by 2 to 3 times. PIC scientists have also developed an “All-Inclusive” buffered and retarded HF acid system used to remove silica fines plugging at any temperature. This system can be pumped at slower rates, without acid preflushes to avoid moving fines beyond the reach of the fines dissolving modified HF acid. As a one-step acid, this chemistry can be more effectively diverted to penetrate targeted damage and achieve greater zonal coverage. This chemistry can use a higher strength HF than conventional HF acid systems limited to 3% HF, thus enables the pumping of small screen/perf cleaning volumes, treating highly damaged sandstones (very high HF acid soluble skins), water injection, and geothermal wells.
Besides improving Deepwater well performance, PIC provides unique solutions to routine subsea challenges such as wax and hydrate removal, enhanced mechanical pigging performance, and specialized suspension and transmission fluids for smart pigging operations. These approaches involve safer, more economical, environmentally responsible chemistry that is compatible with pipeline and refinery requirements.
