Radial fishbone SAGD

摘要

The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. A central wellpad originates injector and/or producer wells, arranged in a radial pattern, and either or both provided with multilateral wells, thus effectively expanding the coverage.

主权项

1. A well configuration for steam assisted gravity drainage (SAGD) production of hydrocarbons, the well configuration comprising:
a) a central well pad; b) a plurality of horizontal production wells radiating in a radial pattern from said central well pad at a first depth at or near the bottom of a hydrocarbon play; c) a plurality of horizontal injection wells radiating from said central well pad at the same or lesser depth than said first depth; and, d) a plurality of horizontal lateral wells originating from said plurality of horizontal production wells or said plurality of horizontal injection wells or both, e) said radial pattern including 6 or more wells radiating from said central well pad.
