... in the annulus, originally the cement in the casing is drilled out and the casing re-log with a bond log then a cement plug re-set in the casing. With experience gained in AWCA, Companies become more and more bolder and accept the performance of the AWCA without further annulus verification. A Qualification...

... to result in a large amount of cement coming over the shakers. The large amount of cement over the shakers was a testament of the efficiency of the system. It clearly shows the capabilities of restoring barriers by removing patchy cement and provide a new high quality cement plug across the interval...

... of temporary plug and abandonment using workover barge is tubing removal, casing removal, and cement plug. To have sufficient power to retrieve tubing and casing, heavy workover unit with capability 225klbs was utilized in swamp area. Slickline and electricline unit in small barge was used to set bridge...

... and successfully executed in the third quarter of 2021. The first successful single trip run of the plug and abandon cementing method was carried out by isolating the 9-5/8" × 13-3/8" casing with an alternative BHA tool. This tool enabled a cement plug to be placed immediately above the alternative BHA tool after...

... coordination with various service partners such as directional drilling and cementing. Placing a good side-track cement plug in such formation was a challenge, and 2 nd challenge to get kicked off from this narrow window in first attempt which was the key.

... deployment of multiple cement plugs using this method to achieve a dependable barrier across a horizontal reservoir section will be reviewed and discussed. A development well in Malaysia lost a bottom hole assembly (BHA) in their 8.5" hole section. This resulted in the requirement to abandon a long...

.... Under the current flow assurance restrictions, the risk of produced water could reduce production rates or require the well to be shut-in. To mitigate water flow potential, cement plug annulus impediments (baffles) were installed. The objective of these plugs are for reservoir management...

... Abstract Setting cement plugs for sidetrack operations is a critical, challenging, and time-consuming operation. In many cases, a successful sidetrack operation requires several cement plug attempts or lengthy drilling operations, resulting in increased operation cost. In the past, when...

... Abstract Certain abandonment operations require plugs to be set off-bottom in a well. The challenge in setting plugs in highly deviated wellbores lies in obtaining a competent hydraulic seal that can qualify as a barrier to any potential flow zones. Failure to achieve a good cement plug leads...

... Abstract Placing cement plugs in high-pressure/high-temperature (HP/HT) wells represents a big challenge, from the standpoint of both the chemistry and the placement techniques. Any failure to properly place a cement plug will lead to costly nonproductive time and will require repeating the job...
