... during a recent working-over. The significant solid production caused casing buckling near the perforation interval. It also activated a weak plane in the overburden, causing further casing damage. This paper will present relevant field data and engineering analyses to support the above conclusions...

... results in upward movement of the overburden, and thus heaving of the free ground surface. This paper proposes an analytical method to estimate the surface heave induced by the steam injection. The method was used to investigate the surface heave profiles under horizontal well injection. It was found...

After the chamber reaches the top of the formation, the injection pressure is lowered throughout the remainder...

These deformations may not exert detrimental effects to casings and facilities if the deformation properties of the overburden are homogeneous without local drastic variation along depth. However, if there exists some natural (clay seams) or induced weak layers (swollen and softened shale layer...

The geomechanical behavior of porous media has become increasingly important...

... Abstract Reservoir compaction and associated bedding plane slip and overburden shear can induce damage to wells. Casing damage leads to loss of pressure, impairment, pinching of production tubing, or an inability to lower workover tools. Usually, casing impairment arises through shear owing...
