... of Underground Sources of Drinking Water ("USDW") within the state. A key aspect of this regulatory framework is the operation of water injection wells under a maximum allowable surface pressure ("MASP") to ensure that injected water does not induce and/or extend formation fractures that could create a potential...

... anticipated surface pressure (MASP) that does not exceed 5,000 psi and are considered low-pressure wells. The working pressure of the lowest-rated component in the well control stack, including the operator's wellhead, is typically 5,000 psi. Therefore, CT interventions in Alaska on wells where the MASP...

... was delivered to the operator. Many ke y challenges were associated with this intervention. The biggest challenge was the absence of previous such experience in a well in Alaska where maximum allowable surface pressure (MASP) exceeded 8,500 psi. The intervention would require well control equipment and other...

... (outside of subsea testing) in excess of MWP were almost exclusively limited to accidental or emergency use. MASP (Maximum Allowable Surface Pressure) is a separate area where there are no industry standard safety factors; such should be developed and integrated with equipment safety factors for a single...

... was 5880mTVD with a MASP of 9,700-psi for gas reservoir. Coiled Tubing was the most viable option to identify the problem, to solve it and to regain access to the lower completion and then proceed with interval abandonment program. This being an unconventional well in multiple aspects, presented serious...

... these fractures and cause typical "breathing" issues); Ability to ascertain the limits of the drilling margin "on-the-fly" and carry out e.g. open hole leak off tests (LOT) that can provide more accurate information on maximum allowable surface pressure (MASP) when dealing with well control events...

...) and a considerable time and cost savings compared to the conventional approach. Unfortunately, there is currently no method available to decide upon the best MPD-CBHP response during an influx, because such a response depends on many parameters, such as Maximum Allowable Surface Pressure (MASP), wellbore geometry...

... on a barge 125-ft away from the wellhead. A CT drilling tower was used to provide stability to the wellhead stack. The wellbore conditions (11,300 psi MASP and 313 deg F BHT) increased the complexity of this operation further, requiring a very thorough job planning process. A mock rig-up of equipment...

... be recognized and diagnosed as soon as possible in the early of recent year, while drilling17 1/2" hole of well no. A-11-20, at depth 383m, huge flow of gas was observed and after closing the well, as the formation below shoe was fractured, due to increase pressure to above MASP, gas flowed from seabed...
