Horizontal wells placement experience for Hard-to-Recover reserves development on the West Salym oil field
Abstract
Salym Petroleum Development is implementing a low permeability waterflood pilot in the West Salym field with the objective to de-risk the development of hard-to-recover Achimov reserves. The waterflood pilot pattern consists of vertical water injector wells stimulated with single fractures and horizontal oil producer wells with multiple fractures. In this article we present a comprehensive horizontal well placement approach which comprises the following key elements: Interpretation of 3D seismic and the use of logs of nearby wells and a 3D static model for well trajectory planning; following a pre-agreed geosteering procedure while drilling, on-site analysis of cuttings and LWD data to adjust the well trajectory and, thereby, optimize well placement.
