Abstract: The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. Fishbone multilateral wells are combined with SAGD, effectively expanding steam coverage. Preferably, an array of overlapping fishbone wells cover the pay, reducing water use and allowing more complete production of the pay.

Abstract: Methods and systems related to SAGD injection and/or production wells that utilize flow distribution control devices. Additionally, methods and systems using limited vertical spacing separating the wells are described. These methods and systems improve steam assisted gravity drainage (SAGD) oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.

Abstract: 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.
