摘要： Disclosed are methods for producing hydrocarbons from a subterranean reservoir. The methods comprise penetrating the subterranean reservoir with a plurality of well pairs that are laterally displaced across a well pad in an array. The methods further comprise operating the plurality of well pairs under a first set of conditions that induce a solvent-concentration gradient, a temperature gradient, or a combination thereof within the subterranean reservoir by: (i) injecting varying concentrations of steam, solvent, or combinations thereof across the array, and (ii) producing hydrocarbons from the reservoir via the plurality of well pairs. The methods further comprise operating the plurality of well pairs under a second set of conditions that delocalize the solvent-concentration gradient, the temperature gradient, or the combination thereof across the array to enhance hydrocarbon production.

摘要： The present disclosure generally relates to harvesting geothermal energy from mature and near end-of-life oil and gas reservoirs that have been subjected to secondary oil recovery steam processes like steam-assisted gravity drainage (SAGD), steamflood, etc. The geothermal potential of these mature SAGD reservoirs can be used to generate green electricity thus reducing the greenhouse gas (GHG) footprint of the oil production. Lateral spacing of injectors and producers, with closing of unused members of a well-pair for energy recovery is described.

An injection module operatively coupled to the pipe rack module. The injection module providing a high pressure steam via at least one high pressure steam line to an injection well. A production module operatively coupled to the pipe rack module. The production module receiving an emulsion into a produced emulsion line from at least one production well. The hub module permits the injection module to be located on either the first side or the second side of the pipe rack module and the production module to be located on either the first side or the second side of the pipe rack module.

摘要： A multi-circulation heat recovery steam generator (HRSG) for steam assisted gravity drainage (SAGD)/Enhanced Oil Recovery (EOR) processes comprises a steam drum internally partitioned to provide a clean side and a dirty side. The clean side downcomer pipe supplies water to one or more generating banks as part of a clean circuit located in a high heat flux zone of the boiler. Boiler water is fed from the clean side of the drum to the dirty side of the drum via natural head differential. Water is then fed through a corresponding downcomer to a dirty generating bank, which is located in a low heat flux zone of the boiler.

摘要： A method and electromagnetic ranging system for determining the location of a target well. A method may comprise taking a first measurement with an electromagnetic ranging tool at a first position and calculating a first modeled signal. Additionally, calculating a calibration for the electromagnetic ranging tool from at least the first measurement and the first modeled signal, taking a second measurement with the electromagnetic ranging tool at a second position, and calculating a calibrated measurement. The method may comprise determining a distance, direction, and/or orientation to a target wellbore using at least the calibrated measurement. An electromagnetic ranging system may comprise an electromagnetic ranging tool and an information handling system coupled to the electromagnetic ranging tool. The information handling system may be operable to calibrate the electromagnetic ranging tool, calculate a gain of the electromagnetic ranging tool, and apply the gain to a measured signal from the electromagnetic ranging tool.

摘要： The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.

摘要： Methods, systems, and computer program products for generating a schedule for fluid placement. A computer-implemented method may include determining, for each zone of a plurality of zones of a treatment interval to be treated by the fluids placement system, a criterion value based on a heterogeneity parameter of the zone, sorting the zones into an ordered sequence based on the criterion value associated with each zone, and generating a schedule that designates an order of treating the zones in accordance with the order of the sequence.

摘要： A sensor arrangement using an optical fiber and methodologies for performing an analysis of a subterranean formation, such as a subterranean formation containing a hydrocarbon based fluid. The sensor arrangement may be used to measure one or more physical parameters, such as temperature and/or pressure, at a multiplicity of locations in the subterranean reservoir. The sensor arrangement may comprise a sensor array comprising an elongated outer casing for insertion in the subterranean formation and into a fluid in the subterranean formation. The sensor array may comprise an optical fiber defining an optical path that links one or more temperature sensors and one or more pressure sensors and transports measurement data generated by the temperature and pressure sensors. A data processing system may be connected to the sensor array to receive measurements from the sensor array and to compute one or more values of a property of an extraction installation operating on the subterranean formation.
