Formation damage

Well deliverability is a critical economic factor in many field developments and directly impacts the bottom line of a reservoir asset. Any fluid that contacts the reservoir during drilling or well operations may induce formation damage and compromise well productivity. The industry relies on core tests to qualify drilling and well fluids for reservoir compatibility. Well productivity is a priority R&D area at IRIS and custom testing services at IRIS - Petroleum laboratory are an integral part of this research.

Formation damage is evaluated on reservoir cores by measuring the return permeability on cores exposed to candidate fluids. IRIS offers two complementary levels of testing: a "basic" test and a "diagnostic" test. Diagnostic experiments, recommended if basic tests indicate formation damage, include dynamic exposure of the core at fully representative down-hole conditions and measuring the damage profile in addition to the conventional parameters. The advanced experimental skills and equipment of IRIS-Petroleum Laboratory allows fluid qualification at extreme conditions, such as in excess of 150 oC and with corrosive fluids. Experiments are routinely customised for specific requirements.
