Abstract: A procedure and apparatus for cementing and cleaning a reservoir liner 3 comprises installing a reservoir liner using a drill string 4 which extends only as far as the distal end of a cased part 2 of the well, then, using the drill string, displacing cement into the reservoir liner using completion fluid whereby, when the cement is in place in the annulus around the reservoir liner, the reservoir liner is already clean and filled with completion fluid. A ball valve 6 at the top of the reservoir liner 3 is then closed before the cased part 2 of the wellbore is cleaned, to avoid debris entering the reservoir liner.

Abstract: This disclosure describes a novel method for predicting or estimating rock mechanical properties from cuttings at a particular depth based on determining the facies, plotting the facies on a ternary diagram with clay, silica and carbonate endpoints, and estimating rock mechanical properties based on comparison to a database of core samples from vertical wells that is also organized by depth and facies. We have shown that datapoints at similar locations on the ternary diagram will have fairly similar rock properties. These rock properties can be used to improve the reliability of a variety of reservoir modeling platforms, which can then be used in designing and implementing completion, stimulation and production plans.

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.

Abstract: A delayed fin deployment wiper plug has a tubular body, which has a closed top and a piston therein. The piston is supported at one or more locations inside the tubular body by one or more sets of shear pins or spring clips or some equivalent device. The piston is connected to or abutted to a sleeve that covers an upper portion of the tubular body, containing therein one or more sets of deployable fins that are not exposed for use unless the piston is activated and raises the sleeve.

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. The wash pipe 9 is made from flush jointed tubing which allows the seal to be uninterrupted as the wash pipe is withdrawn.

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.

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.

Abstract: The present invention relates to a method for reducing solvent retention in ES-SAGD process so as to increase process economics wherein an anti-retention agent is injected into the reservoir to decrease solvent retention in the reservoir. The anti-retention agent can be made pre-injection or can form in situ, and comprises an agent in which the solvent is readily soluble, such that the solvent partitions into the foam, colloidal dispersion, or gel, and out of the condensed water or steam, and away from the reservoir rock.
