Patent number: 11428086Abstract: Single well SAGD is improved by having one or more injection segments and two or more production segments between the toe end and the heel end of a flat, horizontal well. The additional injection points improve the rate of steam chamber development as well as the rate of production, as shown by simulations of a central injection segment bracketed by a pair of production segments (-P-I-P-), and by a pair of injection segments with three production segments (-P-I-P-I-P). Although the completion of the single well costs more, this configuration allows the development of thin plays that cannot be economically developed with traditional SAGD wellpairs.Type: GrantFiled: February 26, 2021Date of Patent: August 30, 2022Assignee: CONOCOPHILLIPS COMPANYInventors: Qing Chen, Wendell P.

Patent number: 11401777Abstract: Methods of plugging a hydrocarbon well by a through-tubing technique wherein the tubing is left in place, and only very short (<5 m) sections are cut, milled, perforated, ruptured and expanded, or combinations thereof. A blocking device is sent downhole if needed to block a bottom of the plug section, and resin dropped onto the blocking device to make a first plug, then cement is deployed onto said first plug to form a second plug. Therefore, the final interval is plugged with a two material binary plug. Once completed, and both primary and secondary barriers are in place, the well can be closed and the Christmas tree removed. A rock-to-rock plug can be set by removing or partially removing the tubular and the outer casing, or just inner casing/tubulars can be removed if the exterior cement and casing are of sufficient quality.Type: GrantFiled: July 13, 2020Date of Patent: August 2, 2022Assignee: CONOCOPHILLIPS COMPANYInventor: Randall S.
