Abstract

Horizontal multi-fractured wells nowadays are the most common way of low-permeability reservoirs exploitation either in Russian and foreign oilfields. Besides its high efficiency such completion has a lot of factors (usually undefined) which can together significantly decrease oil rate. Here some of them are listed: Drilled horizontal well length and producing well length • Number of created and producing fractures • Fracture length by design and by the actual production and well-test • Fracture location in relation to well (azimuth and initialization interval). • Interference between neighborhood wells through the fractures during injection and production • Etc. • The paper deals with most interesting parts of a complex project which purpose is to realize the multi-fractured well potential and production system diagnostics. There are three main issues in this paper: Designing – filed-sector choosing, optimum spacing and well completion calculations Realization – well construction and studies conduction Analysis – comparison between new project wells and common wells in the neighborhood, geological and hydrodynamic model correction Current primary project result is a significant exploitation system efficiency growth after a change of well and fracture directions (perpendicular to the wellbore). The secondary but anyway very important results are learned lessons and new competences in well construction and studies.
