SPE WA is proud to present the details of our April technical evening meeting. About the Presentation The Sangomar Field Development, located offshore Senegal, will consist of 23 wells over stacked reservoirs, with horizontal lengths up to 1500 m. Oil production and water injection will commence during the drilling campaign. Therefore, the reservoir pressure in the wells executed post start-up may be inflated, depleted, or both, reducing the available mud window and impacting the drillability. In this presentation, we will describe the process of identifying vulnerable wells by a combination of a deterministic borehole stability assessment of mud weight windows and a probabilistic well-by-well analysis of reservoir pressure at the…
