Forecast of productivity in the design of the field development scheme with horizontal wells based on the use of new methods of seismic data processing

Abstract

Summary The use of new methods for processing seismic data makes it possible to refine the tectonic model of the field, to forecast zones of increased and decreased productivity in the production horizons. This is necessary for a reasonable choice of directions and lengths of horizontal and directional wellbores in the most fractured zones in order to maximize production rates. The fracture zone map serves as the basis for the design of the field development scheme. Initially, it is recommended to lay wells in zones of increased fracturing of the productive horizon, while avoiding or taking into account the zones of possible complications during drilling, which are present in the overlying horizons. If the location of the well pad has already been determined, the resulting map will help to adjust the azimuth and length of the horizontal sections of the wellbores to undercut the zones of increased productivity.
