..., called "bandage cementing", and it was successful in repairing casing leaks near the surface with over 75% success rate. The focus of this technique is to build a column of cement in annulus between production casing and surface casing to create a "bandage" covering all leaking points in production...

... casing leaks but none were successful. It was the first time that a sealant system provided a solution to repair a casing leak and hold a high pressure differential. During recompletion, the production packer failed to set but the operator decided to initiate production. A annulus pressure increased...

The high-frequency pressure monitoring (HFPM) technique was used during several multistage fracturing operations. We present a case where the degradable diverter was used to effectively plug a leak...

Given the nature of Well-A's completion, a flowmeter log could not pinpoint the source of leak. As an alternative...

... attributes can be of important value to operators when undertaking well integrity assessments. All turbulent liquid or gas flow in a well produces ultrasound. Turbulence is created around leaks, at well entry and exit points and as fluid finds a path through failed barriers, seals or annulus cement. Usefully...

... confirmed the suspicion. Small tubing leaks that were allowing produced gas inside the tubing to seep through to the annulus were found. These leaks could have allowed the pressure to increase, and possibly, could have caused the casing to collapse. In order to produce through the annulus, the pressure...

.... These risks are primarily associated with (a) contamination due to drilling wastes (muds, produced waters, byproducts, etc.); emissions from drilling sites and potential runoffs, (b) natural gas/oil leaks and spills, and (c) direct effects on human health. The drilling fluids circulated through the well hole...

... the ratio for shale varies from 0.25 to 0.40. The formation below the casing seat is commonly tested to its leak off pressure, or to some preselected pressure (limit test) which satisfies the bore hole pressure integrity requirements. The formation leak off pressure is generally lower than the formation...
