A diversified production base
In 2009 we undertook a major subsurface re-evaluation exercise on the Lion and Panthère fields. This involved integrating all available log, core and seismic data to define the Cretaceous depositional systems active over the fields. The results of this detailed work have been incorporated into reservoir geo models and up-scaled to reservoir simulation models in order to history match production since 1995.
The outcome of this work is that a number of potential new reservoirs have been defined in addition to infill drilling opportunities in existing reservoirs. We are also focused on ways to best address low recovery factors in some field reservoirs via sidetracks of current wells. Furthermore, we are also looking at pressure maintenance via water injection as a means of enhancing the productivity of current production wells. Studies are ongoing in all these areas. This work has not yet been independently assessed by NSAI.
2010 outlook
2010 will see a continuation of the detailed geoscience work undertaken in 2009, which will be combined with reservoir simulation modelling in order to firm-up a work programme that will potentially increase the reserve base and production levels at CI-11.
A wireline programme has been initiated to clear potential wax accumulations within the well bores in preparation for work to optimise the gas lift systems, and potentially perform water shut-offs and perforate bypassed oil and gas pay zones.
