DISLODGE FRICTION REDUCERS & PORE THROAT PLUGGING 

A friction reducer (FR) is a high-molecular-weight, anionic, and water-soluble
copolymer approximately 1,000 nanometers in size (1 micrometer). FRs in micropores less than 1,000 nm can plug the pore throats and pores, reducing oil and gas permeability and causing skin damage. As a result, well production rates suffer and ultimate recovery declines.

nanoActiv® has proven to remediate fines migration and break through clogged pores caused by friction reducers.

NITRO-LIFT TECH TIPS: VOLUME 2

PREVENT FORMATION DAMAGE DURING SHUT-IN

Formation damage from shutting in a well can result in a loss of capital in terms of not just lost production but also lower ultimate recovery. Operators fear once a shut-in well is turned back on, the well will fail to return to pre-shut-in production rates or even worse, fail to begin producing again at all.

During shut-in, asphaltene deposition primarily causes damage to oil reservoirs, resulting in the impairment of the reservoir formation permeability due to plugging of the pore throats by asphaltene particles.

While it may seem a good preventative measure, current methods of injecting low surface tension fluids into asphaltenic oil reservoirs may cause asphaltene precipitation.

nanoActiv® is the ONLY treatment that is able to coat the rock surface in pore throats to prevent asphaltene deposition during shut-in.
