OIL EXTRACTION SYSTEM AND METHOD

摘要

A system for extracting crude oil is discussed herein. The system includes a main shaft and one or more horizontal drifts extending from the base of the main shaft, which are located subjacent or below a reservoir trap or oil formation. A plurality of production boreholes are drilled upwardly from the horizontal drift towards the reservoir trap to gather the oil mixture and direct it to flow, either by gravity or from reservoir pressure at an angle towards the drifts below the formation. A manifold or distribution system located in the one or more horizontal drifts collect flow from the plurality of production boreholes. The collected flow is either pumped or lifted to the surface for separation, treatment, and/or processing or alternatively treated before pumped or lifted to the surface.
