Energy service companies maintain oil and gas production from existing wells through a process referred to as Stimulation. Within stimulation, there are two critical operations needed to exploit and maintain production from existing wells and reservoirs which includes hydraulic fracturing and coiled tubing. In hydraulic fracturing, shale rock is permeated with high pressure fluids and porosity within the rock is maintained with the placement of sand carried by gels and other high viscous fluids. During production, a common intervention technique termed coiled tubing is used to reverse production impairment by delivering chemicals within the tubing and laterals to remove flow blocking deposits which can occur over time.
Stimulation operations can have associated challenges when developing and maintaining oil and gas production efficiencies. The hydraulic fracturing process must be efficient and ensure the reservoir can transport oil and gas to the surface. In coiled tubing applications, chemicals must be effective in removing and reducing restrictions in tubing. Some of the key challenges to both processes include:
Solugen addresses these challenges with a clear understanding and working partnership with service companies to provide high performing, environmentally acceptable, and economical solutions to meet their operational requirements in oil and gas well stimulation.
Solugen’s solutions are backed by lab performance testing and historical case studies to provide the necessary information for operating and service companies to make informed decisions on production enhancement through stimulation operations.
ScaleSol™ is an environmentally acceptable replacement for phosphonates and has a high tolerance for iron which is a common sludging precipitant requiring removal in stimulation operations (coiled tubing).
ScavSol® is a multivalent sequestrant to inhibit precipitating metal salts in coiled tubing operations and prevent polymer gel breakdown in the hydraulic fracturing process. It is unique in that it does not contain sulfates which can contribute to microbiological growth, corrosion, and hydrogen sulfide evolution.
CorrSol™ is designed to prevent under deposit corrosion, fouling, and maintain clean operating surfaces to reduce corrosion in tubulars and flowlines in high and low brine fluids.
