The grouping of planned wells for well pads location by multi-layer field

Abstract

An approach to improving the project quality of a multi-layer field development, which allows to bring the project to the real conditions of the field development, to reduce its capital intensity is proposed. The key task is to find the optimal pads distribution pattern based on the development system of target operational facilities, which ensures the formation of development elements at dependent production facilities at the expense of transit wells. This takes into account the purpose and mode of wells operation. This arrangement of well pads should ensure minimal capital costs and technological risks in the implementation of the project due to multi-factor optimization. For this purpose, length and complexity of trajectory wells, infrastructure, natural and environmental restrictions on the field territory, technical restrictions in wells construction are taken into account. Such problem for multi-layer field is not solved by existing software systems. A method of grouping the project drilling targets, as a stage of well pads distribution, based on modified clustering method k-means is considered. The clustering algorithm is adapted to minimize the total penetration of inclined and horizontal wells, taking into account the complexity of their trajectories.
