... contribute to their potential for instability during cementing operations. The integrity of cement barriers is paramount, as failures can lead to gas migration, loss of hydrocarbon resources, and environmental hazards. The geological landscape of the field includes a variety of formations, each...

... Abstract The thermal conductivity (TC) of the cement is one of the important parameters used in different simulations and numerical models to find or predict the integrity of the well cement, especially if the old oil and gas wells have to be retrofitted for geothermal or Carbon Capture...

.... The savings provided by the use of this solution reached around US$ 333 million in this period. The article's purpose is to present an integrated management strategy to guarantee optimal results for the proposed application. Proper service personnel training associated with a dynamic result publicity...

... Abstract One of the main issues surrounding any casing recovery operation is the integrity of the cement and cement-bond behind or between casing strings. To successfully retrieve casing to surface the integrity of this bond must be either removed entirely or reduced to a level where the casing...

...) . Abstract Horizontal liners in extended-reach drilling (ERD) wells can experience severe loading during running. Sometimes, downhole loads approach the limits of the tubular system and must be actively managed to ensure long-term well integrity. This paper describes a Canadian thermal operator's approach...

... those assumed in conventional drilling design. This may affect well integrity and should be checked. Load cases for an MPD well are quite similar to those in a conventionally drilled well. However, some loads definitions may vary. Also, some loads unique to MPD conditions will need to be checked...

... this successful experience, which was a result of well planning and operational efforts focused on logistics, tubing selection and integrity assurance, torque management procedures, ECD control, fluid properties with lubricity approach, and rig crews prowess to handle and drill with a string much different than...

... Abstract Quality of cement is an integral part of well integrity. To ensure and improve cement quality, innovative polymers, based upon a family of polymers known as polyamides, are synthesized to improve the mechanical properties of Portland cement. This results in cement systems that have...

... of wells in Norway to be P&A’d including the need to comply with Norsok Standard D-010 ( Norsok, 2013 ). Many technologies have come to the forefront to aid with safe permanent well abandonment, with different criteria to be met, principally by verifying the integrity of the casing and cement barriers...

... Continental Shelf (NCS) alone, over 3,000 wells need to be plugged and abandoned ( Myrseth et al., 2017 ). When also considering the environmental responsibility associated with P&A of oil and gas wells, it is clear why reducing the operational expenses as well as ensuring proper integrity of the plugged...

..., pressure channels at the top- and bottom side of the cement plug now can be regulated separately. Abstract Cement holds the most critical role for providing long-term zonal isolation for permanent abandonment phase. The loss of cement integrity is undesirable as it may threaten the surrounding...

... Abstract Brazing technology allows metallurgical joining of dissimilar materials using a filler material. In this paper brazing technology applied to casing connections is presented. The initial application was triggered by challenges with mechanical and pressure integrity after expansion...

... Abstract This paper presents a comprehensive workflow for determining reservoir compaction and seabed subsidence through a case study on a deepwater gas development in Equatorial Guinea. It shows how a 4-D coupled reservoir geomechanical model can be used to evaluate well integrity risk...

... casing integrity requiring intervention of wells because of the short lifetime of stage-cementing equipment. They have been forced to select other, more costly and more time-consuming methods (requiring four to six trips), such as installing a liner hanger and a tieback to surface. Although these methods...

... to verify knowledge, criteria for drills to check on team capability and periodic inspections to ensure equipment integrity. Although difficult to achieve, the process must be carried out in a way that engages the crews in a sense of self-preservation to avoid becoming a box ticking exercise. Drilling...

.... Incident data regarding well integrity, marine integrity and fire/explosion incidents is being actively captured and these data categories, which are seen to represent the most significant process safety threats in an offshore drilling environment, were retroactively applied to earlier incident data...

... Abstract Tubular connection integrity is a key to short-term and long-term well integrity. The stress on the tubular and the connection, particularly in high-pressure, high-temperature wells, creates challenges for connection providers. Proper selection of makeup method is essential...
