Summary on Grant Application Form
Operators recognise the need for time-lapse reservoir monitoring as part of the reservoir management process. Key issues are mapping fluid flow and by-passed oil zones remote from boreholes. This knowledge leads to reduced uncertainty in the development and application of predictive reservoir models. The next step-change in reservoir monitoring will come from the increased resolution and sensitivity of permanently deployed borehole geophysical sensors.Electrical borehole measurements are the main stay of reservoir evaluation. Electrical logs are more sensitive than seismics to many of the reservoir processes (i.e. changing fluid saturation) that are required for improved reservoir modelling. Time-lapse electrical reservoir measurements made using permanently deployed arrays of sensors as an integral part of the well completion are therefore the logical next step in near-wellbore and inter-well fluid flow imaging. However the task of developing oilfield deployable electrical imaging systems is considerable and involves the design and evaluation of engineered systems, development of processing techniques and the integration of the systems into intelligent well completions.The aim of this project is to undertake the necessary investigations required to ensure the successful development of permanently deployed electrical imaging arrays as part of intelligent well completiions. Proof-of-concept borehole demonstrations and a detailed development and implementation plan will be used to ensure future demonstrations in oilfield environments.Specific project objectives include;1. Evaluation of measurement sensitivity and resolution. 2. Data inversion and interpretation schemes. 3. Sensor design and installation. 4. Proof-of-concept field trial. 5. Technology development and implementation plan.The partners are a global oilfield technology company and supplier of intelligent well technology (ABB Offshore Systems Ltd) and a research group specialising in borehole geophysical imaging technology (Imperial College of Science, Technology and Medicine).
