oa Deployment of Advanced Sidewall Coring Technology in South Iraq as Efficient and Cost-effective Alternative for Coring

To achieve the production objectives, big number of deviated wells are being drilled in the study area in South Iraq where a lot of drilling-related challenges are observed when going deviated across some sections. And, due to planned sustained production over years seal integrity needs to be assessed as well against further production and injection objectives. Therefore, there is a need for geomechanical studies in the field. The advanced triaxial geomechanical analysis requires large-sized core-plugs. Advanced rotary sidewall coring on wireline saved a lot of time and money compared to conventional full-bore coring in the study area in a four-well project, while efficiently retrieving 3.0”×1.5” size core-plugs directly from the sub-surface based on log-interpretation guided depths in varying lithology of shale, salt and anhydrite in a single descent. Thus, the need for conventional coring is minimized with deployment of the new large-format sidewall coring technology for geomechanical studies in South Iraq.
