Abstract: A process for removing metals and chelators from SAGD liner flowback that can be implemented at the wellhead using temporary tankage and equipment. In the first step, caustic is added to the flowback until the concentration of hydroxyl ion is high enough for the metals (Fe, Ca, Mg) to dissociate from the metal-chelate complexes and precipitate as hydroxides. In the second step, hydrogen peroxide is added and allowed to react until all of the chelator molecules are oxidized and decomposed. Once treated, the flowback can proceed to the CPF.

Abstract: 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.

Abstract: A method of optimizing production of a hydrocarbon-containing reservoir by measuring low-frequency Distributed Acoustic Sensing (LFDAS) data in the well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow and simultaneously measuring Distributed Temperature Sensing (DTS) data from the well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow. An initial model of reservoir flow is provided using the LFDAS and DTS data; the LFDAS and DTS data inverted using Markov chain Monte Carlo method to provide an optimized reservoir model, and that optimized profile utilized to manage hydrocarbon production from the well and other asset wells.

Abstract: The invention relates to the fluid treatment, such as acid stimulation, of a subsea hydrocarbon well via a subsea wellhead/Christmas tree. Fluid is delivered directly to the subsea wellhead from a pumping vessel. Control of the delivery of fluid is from the pumping vessel via a fail-safe close valve in the delivery line. The Christmas tree subsea module is controlled directly from a host platform via a subsea cable, whilst a radio data link between the vessel and host platform provides communication of downhole data to the pumping vessel during the operation.

Abstract: Implementations described and claimed herein provide systems and methods for removing nitrogen during liquefaction of natural gas. In one implementation, a nitrogen rejection unit is used in an LNG facility to remove nitrogen from natural gas during an LNG liquefaction process. The nitrogen rejection unit contains at least two columns and at least one 3-stream condenser, 2-stream condenser or a two 2-stream condenser.

Abstract: Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, an acoustic signal is obtained. The acoustic signal is captured at a set of acoustic receivers deployed in a structure in a subterranean surface. A differential acoustic signal is produced from the acoustic signal captured at the set of acoustic receivers. A symmetry within a portion of the structure is determined based on a value of the differential acoustic signal. At least one isolation region is detected within the structure based on the symmetry.

Abstract: The invention relates to an arrangement for seismic acquisition the spacing between each adjacent pairs of receiver and sources lines is not all the same. Some receiver and/or source lines and/or receiver and/or source spacings are larger and some are smaller to provide a higher quality wavefield reconstruction when covering a larger total area or for a similar total area of seismic data acquisition while providing a wavefield that is optimally sampled by the receivers and sources so that the wavefield reconstruction is suitable for subsurface imaging needs.

Abstract: Method for characterizing subterranean formation is described. One method includes inducing one or more fractures in a portion of the subterranean formation. Determining a poroelastic pressure response due to the inducing of the one or more fractures. The poroelastic pressure response is measured by a sensor that is in at least partial hydraulic isolation with the portion of the subterranean formation. Monitoring closure of the one or more fractures via the poroelastic pressure response.

Abstract: A particularly effective well configuration that can be used for single well steam assisted gravity drainage (SW-SAGD) wherein steam flashing through production slots is prevented by including passive inflow control devices (ICDs) or active interval control valves in the completion. A thermal packer separates the injection and production segments of a horizontal well having a toe and a heel, and the ICDs can be evenly spaced or can decrease towards the heel. The cumulative steam to oil ratio (CSOR) of the SW-SAGD well is thus lowered, as compared to the same well without passive flow control devices or active interval control valves.
