... Abstract Achieving stable laterals for successful deployment of ICD sand screens with swell packers can prove difficult in Southeast Texas reservoirs due to hole instability, tight ECD margins, high clay content, and varying permeability contrasts. Historically, bore hole instability has...

... The layers are filled with the injected gas from the bottom to the top. Consider the reduction in permeability from its initial value, denoted as k ( z ), to reach the stabilized damaged value, represented as k d ( z ). Several physical mechanisms can induce changes in permeability during CO 2...

In this scenario the core plug was initially 100% saturated with formation water, and return permeability was measured by injecting formation water through the core in the same direction as the test fluid filtrate invasion. Testing was conducted at two...

... solids and residues incorporated into the drilling fluid are minimised to reduce the risk of plugging the matrix permeability. Once the well is drilled, ensuring that the breaker fluid is placed across the entire zone of interest and the filter cake is removed in a controlled and uniform manner...

... carbonate, thus improving the wellbore strengthening and reducing formation damage. Return permeability (RP) testing is widely used in the oil industry to evaluate fluid-rock interaction. RP testing indicates potential causes of production impediments generated after drilling by filtercake deposition...

... Abstract One of the key risks for a Carbon Capture Storage (CCS) project is injectivity decline. Evaporation of the connate brine in near-wellbore region during Carbon dioxide (CO 2 ) injection may result in migration of clay particles leading to decline rock permeability and consequent loss...

... in permeability (37% -75% impairment) and porosity (18% to 33%) due to salt precipitation. Among the treatments, LSW exhibited the lowest efficacy, followed by freshwater, possibly due to clay swelling, fines migration, and capillary trapping effects causing pore throat blockages. In contrast to freshwater...

.... The model utilizes a description of the fluid distributions withing the pore structure to determine the fines detachment during progressive sweep of the reservoir by an aquifer. In heterogeneous reservoirs, an extension of the Dietz model is used to calculate pseudo relative permeability curves accounting...
