Chemical and thermodynamic reactions that cause formation damage are a major contributor to unexpected declines in productivity or injectivity in most reservoirs. Understanding the damage mechanisms and testing mitigation techniques can optimize well operations.
Capillary Suction Time/Roller Oven
Fluid sensitivity screening designed to provide an indication of clay swelling associated with various water-based completion fluids and to determine the reduction of particle size through the simulated circulation of completion fluid of the rock particles.
Injection of fluid at various flow rates to determine when fines become dislodged and reduce permeability. Damage caused by fines migration can occur during drilling, completion, attempted stimulation, production, and anytime during injection.
Permeability as a Function of Throughput
Dynamic flow testing that provides insights into various damaging mechanisms such as changes in salinity, pH, fines migration, or chemical composition.
Dynamic flow testing that is used to evaluate potential damage caused by drilling mud or completion fluid on the reservoir rock.
Unpropped Fracture Conductivity
Provides an understanding of the effects of stress, completion fluid sensitivity, and fines migration on unpropped fracture conductivity.
Reservoir condition flow testing designed to evaluate flowback aids/surfactants added to improve the productivity of unconventional low permeability formations that have been adversely affected by the invasion of frac fluid filtrate.
