... of Current Oil In Place (COIP) of 10.0 MMBO and 11.3 MMBO for reservoirs A and B. A non-rig workover (NRWO) and 2 new drills were identified with potential Estimated Ultimate Recovery of about 6.67 MMBO. A pilot well from one of the proposed new drills is aimed at proving up additional up-dip reserves...

... configurations. First, using available petrophysical information, a method is presented to estimate recovery factor ranges and the corresponding residual saturations which is then used to constrain material balance models in prediction of ultimate recovery. The reservoir is then divided into drain sections...

... Abstract The essence of reservoir simulation is to forecast field performance, ultimate recovery and to evaluate the effects of different operational conditions on recovery while keeping the economics of each scenario in view. It is important to note that in simulation one...

... an expectation STOIIP of 1602.2MMstb with ultimate recovery of 520.9MMstb (RF 33%). The cumulative production from the field as at 1/1/2006 was 300MMstb and expectation reserves at 1/1/2006 was 89.5MMstb, meaning an opportunity gap of 130.8MMstb remains for which projects could be identified. The field...

The reservoir is sub-divided into separate blocks and it has over 25 years of production with evidence of over-production (Np > Ultimate Recoveries) experienced in some of these blocks. This over...

Performance data from the producing wells were used to calibrate the simulation model to ensure consistent ultimate recoveries estimation. The estimated developed ultimate recovery from...

This study highlights the importance of carrying out further studies on our brown fields to re-evaluate the earlier estimated hydro-carbon Inplace volumes and its ultimate recovery by integrating historical information (performance data etc) and emerging development plan...

... Gas Initially In-Place estimate is required first of all before considering dynamic factors that will influence ultimate recovery and hence optimum development of a gas field. Two broad methods exist for this estimation – static volumetric and performance or dynamic methods. The more appropriate...

Five scenarios of a marginal field reservoir were modeled: no water influx, bottom-water influx, edge-water influx and combined edge- and bottom-water influx. Results obtained from the numerical simulation model...
