Expanding the Envelopes of Openhole Gravel Packing in Sabah Deepwater Malaysia

Amongst the challenges encountered during infill drilling and completion is the requirement to penetrate depleted zones drained during the early phases of the field development. This condition is exacerbated for completions requiring openhole gravel pack as the maximum openhole lengths are traditionally limited by the effective circulating density experienced during the openhole drilling and gravel packing. This paper discusses the techniques implemented in four openhole gravel pack completions with openhole lengths up to 858m marking a new record for the longest openhole completed by PTTEP in this field. The wells were deployed by PTTEP in the Malaysian Deepwater Block K, during the field development of Siakap North Petai Phase 2, executed between Q4 2021 and Q1 2022.
