Petroleum allocation method for exploration strategic planning
Abstract
During petroleum exploration strategic planning and study, it is necessary to comprehensively analyze on exploration status, resource basis and engineering technology conditions of various plays, in order to determine resource replacement sequence, petroleum exploration focus and development targets in the future. According to quantitative calculation on exploration status and potential of different plays, a resource allocation method in exploration strategic planning was established. In this method, an exploration status index formula for three key parameters, namely, resource proven degree, exploration well density and 3D seismic coverage density was firstly constructed for quantitative calculation on current exploration status. Secondly, a quantitative evaluation formula for exploration potential was established and incorporated comprehensively with some parameters like interim proven speed that reflected exploration status, resource potential and engineering technologic adaptability. Finally, exploration status index and potential index were put in unified evaluation platform in order to construct a cross plot for these two indexes, and then eight petroleum resource allocation areas were formed. According to the thinking of the strategy defined by the comparison on exploration status and the target by quantitative potential evaluation, petroleum exploration and development focus and exploration allocation sequence in certain period were determined to meet resource allocation requirement on clear status, quantitative potential and feasible technology for various plays. This evaluation method has the characteristics of universality and unique evaluation result.
