Abstract: This paper presents a novel methodology to model semi-steady state horizontal well flow performance in an anisotropic reservoir taking into account flow in the near-well region for an arbitrary well trajectory. It is based on… read more here.

Abstract: Abstract During geologic CO 2 storage, integrity of injection wells is of utmost importance. Tensile radial stresses at casing-cement and cement-rock interfaces caused by relatively cold CO 2 flowing down the tubing may induce debonding… read more here.

DOI: 10.1016/j.ijggc.2018.07.006
Abstract: Abstract To maximize safety and cost-efficiency of CO 2 storage, it is necessary to understand how a high permeability in the near-well region can be maintained. All the injected CO 2 needs to pass through… read more here.
