Partners on the SNE field offshore Senegal have agreed on a firm drilling program for 2017. Cairn Energy (operator), FAR Ltd. and Woodside Energy agreed to a drilling program of two appraisal wells. The wells will be drilled in order to optimize the SNE field development plan before submitting it to the government for approval.
The JV partners completed an extensive rig tender evaluation process and executed contracts for the use of the Stena DrillMAX drillship for the two-well drilling program commencing in Q1 2017. The SNE-5 and SNE-6 wells are located within the SNE oil field and are designed to evaluate the upper SNE reservoir units (400 series), specifically the connectivity of the reservoir section and depositional model interpreted from existing wells and high quality 3D seismic data.
The drilling and evaluation plan is for SNE-5 to undergo drill stem testing (DST) and have permanent gauges placed in the upper reservoir units. SNE-6 is to be drilled immediately after SNE-5, and it is also expected to undergo an extended DST program in order to generate a pulse that will be registered in the gauges installed within the upper reservoir section at SNE-5 and SNE-3.
Successful flow and interference test results that support connected reservoir units are expected to lead to higher than currently estimated ultimate oil recoveries by FAR from these reservoir units.
The JV is progressing towards the submission of a development plan for the SNE field as quickly and efficiently as possible, with pre-FEED activities currently focused on determining the final project size and scope. The SNE-5 and SNE-6 wells are expected to provide important data for SNE reservoir management and will play a key role in optimizing the proposed SNE project development.
The Stena DrillMAX has been contracted for a firm two wells plus additional option wells and the drilling program will commence in Q1 2017.
