Well Placement and Uncertainty Ranking Based On Kriged Production at Early Field-Life Cycle

摘要

This paper deals with the determination of well placement at early stages using information of oil wells based on simulation ru ns, and it is the first part of a research work that only considers synthetic cases. Most of the information is sparse at early stages and the objective of an Exploration and Production company is to develop the field in order to have production as soon as possible. The challenge at early stage of production is to propose the position of wells to be drilled. However, due to the lack of information at the early field life, the problem becomes more challenging. The proposed methodology is based on the conclusions obtained by applying the procedure mentioned above in seven synthetic cases of a squared reservoir of 2700 x 2700 ft, under single phase flow of hydrocarbons through the porous media and corroborated with numerical reservoir simulations, called exhaustive methodology. A period of three months is used to update hydrocarbon production, which is a reasonable time period to have stabilized produ ction. Production maps were generated by means of the Kriging approach, as well as the corresponding uncertainty maps. A good match was found for the analyzed cases.
