Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215351-MS
... Abstract During the water injector workover campaign in 2018, some casing leakage near the surface was identified (depth range 10 to 300 ftRT). Several attempts were made to seal the leakage, but none of them succeeded. In response to investigation, a specific cementing technique was developed...

... and often associated with a low probability of long-term success. Available conventional technologies and techniques mostly use cement as a plugging material. However, steel has several advantages over cement, such as a higher tensile strength, enabling stronger structures with less material; cement...

... Abstract Annular Wash Cement Assurance (AWCA) has been used for several years as a cost-effective tool for Permanent Abandonment (P&A) of oil/gas wells to remediate cement behind casings in lieu of Section milling to establish a rock-to-rock barrier. In order to verify AWCA result...

Paper Number: SPE-205786-MS
...Methodology The main concerns for setting a cement plug in a highly deviated or horizontal well is the very significant possibility of cement slumping or stuck pipe. To avoid repeated plug jobs and to increase the chances of success on the first attempt, four smaller individual plugs were...

... Abstract Following the successful proof of concept of the closed system dual casing perforate, wash and cement for environmental plug application in 2018 (SPE-193989-MS), the same system was optimized for 2 subsea wells to isolate a gas sand behind 2 casings (9-5/8" × 13-3/8" × 16" open hole...

... important now than ever to abandon wells properly and permanently the first time. Given the limitations of cement, bridge plugs and resins, a more reliable plugging material has been needed for years and now there is one, bismuth and thermite. This paper was selected for presentation by an SPE...

... From the outset, the cement recipe was planned as a gas tight slurry ("right angle set"), with an expanding agent to address microannulus concerns. The expanding agent was to be pre-added to the cement mix-water in the batch mixer, and could not be added whilst cementing. The total tail cement...

In their case, the quartz cement was competent enough to result in no net effect on the rock mechanical behaviour...

... Abstract In the recent low oil price environment, a cost-effective solution was proposed to use through tubing bridge plugs to perform water-shut-off (WSO) in an offshore field. The solution consisted of using slickline to set a plug with a high expansion ratio followed by a cement dump. After...
