OPC recently prepared a well test design project on an apprasial oil well in the UK North Sea.
The project was managed by OPC London based Reservoir Engineer Deev Sachdev and involved Bill Roberts as PTA technical expert.
Both provided expert assistance with the overall pre-testing modelling, including advanced well test techniques such as interference analysis. Being utilised in a sense to predict interference on a ‘observer well over 7000 ft away to demonstrate reservoir connectivity.
A test plan was developed, and OPC successfully streamlined the proposed testing schedule, achieving a total reduction of 14 days to meet the client’s objectives. Additionally, an extra analysis was performed to assess connected volumes through Deconvolution, providing the client with a reliable indication of the volume connected to the well.
