  • Patent number: 10808521
    Abstract: This disclosure describes a method of assessing fractures in an underground formation using temperature profile measured by a DTS. The fractures can be identified by a temperature profile established by the feedback signals obtained from the DTS, but the DTS measurements are made at least 36 hours after a stage is fractured and during shut-in, thus allow crossflow and other noise sources to abate. Further, the size of the temperature differential is indicative of fracture spacing or density, not volume of fluid flow as thought in the prior art. Thus, these methods can be used to optimize the next stage or next well in a fracturing program.

  • Patent number: 10794179
    Abstract: A method for obtaining hydrocarbon from a reservoir in a subterranean formation can include measuring a poromechanic pressure change due to lithostatic load sharing in the subterranean formation. The poromechanic pressure change can then be mapped to one or more locations within the subterranean formation. Once mapped, the method can identify one or more local pressure peaks in the poromechanic pressure change, wherein each of the one or more local pressure peaks are marked by a pressure escalation and subsequent pressure depletion. The method can then determine one or more regions within the reservoir exhibiting single phase hydrocarbon production.

  • Patent number: 10760393
    Abstract: Steam assisted gravity drainage (SAGD) equipment including steam generating equipment may be cleaned using supercritical carbon dioxide. Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Supercritical carbon dioxide has exceptional solvent qualities that can dissolve, soften, or dislodge the refractory fouling deposits in the SAGD equipment.

  • Patent number: 10760375
    Abstract: A method of plugging a hydrocarbon well includes deploying a downhole tool to remove at least a portion of a casing at a section of well to be plugged. Deploying a blocking device downhole to block a bottom of the section of well to be plugged. Deploying a plugging material downhole onto the blocking device to fill an area to be plugged. Deploying an exothermic fluid downhole, wherein activation of the exothermic material liquefies the plugging material. Allowing the plugging material and the exothermic fluid to solidify form a cast-in-place plug that fills the section of well to be plugged.

  • Patent number: 10753181
    Abstract: Methods for using shut-in pressures to determine uncertainties in a hydraulic fracturing process in a shale reservoir are described. Data commonly collected during multistage fracturing is used to calculate propped fracture height and induced stresses, as well as other variables, in the presence of horizontal stress anisotropy. These variables can then be incorporated into reservoir simulations for fracturing monitoring, forecasting hydrocarbon recoveries, or modifying fracturing plans.

  • Patent number: 10738567
    Abstract: 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.

  • Patent number: 10731439
    Abstract: The invention relates to a method and apparatus for avoiding fluid loss during installation of a lower completion in an open hole oil, gas or water well. A lower completion assembly 3, 33 comprising tubing with production perforations, for example in a sand screen, is run into the well on drill pipe 8, 38. The lower completion 3, 33 is hung from a packer 4, 34, together with a wash pipe 9, 39 which extends through the inner of the lower completion 3, 33. At the proximal end of the lower completion is a seal 15, 45 through which the wash pipe 9, 39 extends. An aggressive breaker fluid is circulated through the wash pipe, through a float shoe 11, 41 at the end of the completion. Once circulation is completed, the aggressive breaker removes all filter cake from the formation in 30 minutes. The wash pipe 9 is withdrawn but, because the wash pipe 9 seals against the seal 14 as it is withdrawn, fluid is not lost into the formation via the lower completion.

  • Patent number: 10718193
    Abstract: Methods and systems produce petroleum products from a formation by a steam assisted process followed by an in situ combustion process. The steam assisted process utilizes an injector and first producer to form a steam chamber within the formation as the products are recovered. The in situ combustion then starts by injecting an oxidant into the formation and ignition of residual products. A combustion front advances toward a second producer that may be offset in a lateral direction from the first producer. Heat and pressure from the in situ combustion sweeps the products ahead of the combustion front to the second producer for recovery.

  • Patent number: 10685086
    Abstract: The proposed method is an improved method of flooding weak reservoirs and avoiding premature breakthrough of the displacing fluid used in the flooding operation by first modeling the performance of the reservoir under a rage of flooding pressures in a couple geomechanic and multiphase flow model. Ideal pressures are thus selected from use in a flooding operation, thus avoiding rock failure and fluid breakthrough.
