Applying Downhole Sand Control for High Rate Gas Completions in Deepwater Malaysia

Designing and delivering a successful completion in a Subsea High Rate Gas Deepwater environment is known to be one of the most challenging aspects of a Field Development. For the specific case of high rate gas wells with reservoirs requiring sand control, it makes the completion reliability and longevity an uncompromising prerequisite, as it is well known that formation solids moving at high velocity through the wellbore can drastically affect the functionality and integrity of downhole equipment as well as the subsurface and production facilities. In addition, to the previously mentioned aspects, the complexities and costs associated with Well reentries and Workovers in a Subsea Deepwater environment can quickly erode the overall financial viability of a development program. This paper covers the sand control design and execution techniques applied to four (4) High Rate Gas Wells in the PTTEP's Block H Development in the Malaysian Deepwater region of Sabah, between 2020 and 2021.
