... process. Consequently, several recent wells were able to be decommissioned through simpler, safer configurations, and the drilling of several prospective wells was made viable due to less exigent isolation requirements. Given the uncertainty related to the flow potential of shallow intervals...

... impacted by deformation and might result in reduced burst and collapse ratings. Electromagnetic thickness data is used to evaluate this aspect. Integrating the multifinger caliper results with the cement evaluation logs show that the main deformed intervals lack of annular cement isolation. This was key...

... not provide the isolation required for adequate placement of the treatment. The combination of lithology, open hole completion, H2S content and acid treatment, provided a very complex condition, establishing the necessity of incorporating an engineered solution, capable of providing precise fracture...

..., chemical isolation provides one effective solution to this issue. This paper describes a cost-effective coiled tubing (CT) intervention to implement permanent zonal isolation for water shutoff using an organically crosslinked polymer (OCP) sealant system and a modified organically crosslinked polymer (m...

... Abstract Plug-and-perf multi-stage hydraulic fracturing completions in unconventional reservoirs rely upon complete hydraulic isolation from the previous stage to ensure effective treatment of the active stage. Failure to isolate stages can be a result of partially set plugs, plugs set...

... Seeing these channels extending across different intervals of the lateral it became apparent that poor cement quality in horizontal wellbores could impact the quality of hydraulic fracture placement. While plugs are used to isolate fracture stages inside the production casing, the primary role...

... Abstract Currently, hydraulic isolation of wells drilled with nonaqueous fluids (NAFs) relies heavily on the elimination of mud from the annuli before the placement of cement. Failure to expel all NAFs will result in residual fluid channels that will compromise well integrity and can even serve...

... Abstract Cement job design has historically been a static process largely independent of the other processes in the drilling and completion phases. The success or failure of achieving zonal isolation, which is the main objective of cementing, is usually attributed to the cement placement result...
