Abstract: A method starts wells with electrical downhole heating and injects solvent(s) or NGL mixes as a preconditioning for a steam injection process. The downhole electrical heating and solvent injection recovers oil and reduces the reservoir pressure. Once oil has been recovered for a period of time and the operating pressure and temperature has been reduced, steam or steam and solvent(s) may be injected to produce high oil recoveries at faster production rates than downhole heating or downhole heating and solvent(s) injection alone. The method reduces heat losses due to steam injection at lower pressure and temperature and therefore, improves efficiency and lowers operating costs. Operating at lower pressure and temperature also reduces the risk of melting the permafrost and consequent well failure issues.

Abstract: The invention relates to various nonlimiting embodiments that include methods, apparatuses or systems for processing natural gas comprising a heavies removal column processing natural gas and light oil reflux. The overhead stream goes to heavies treated natural gas storage. The heavies removal column reboiler bottoms stream product is input to a debutanizer column. The debutanizer column overhead lights are input to a flash drum where the bottoms is pumped through a heat exchanger as a light oil reflux input to the heavies removal column, while the debutanizer reboiler bottoms product is stored as stabilized condensate. Alternatively, debutanizer column overhead lights are sent to heavies treated gas storage and the bottoms stream product goes to a depentanizer column, the overhead lights are pumped through a heat exchanger as a light oil reflux input to the heavies removal column, while the depentanizer reboiler bottoms product is stabilized condensate.

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 method for mitigating fouling in a once-through steam generator train is described. The method involves obtaining foulant samples from the once-through steam generator train. Obtaining water samples from one or more locations along the once-through steam generator train. Recovering filtered solids from the water samples from the one or more locations. Characterizing at least one physical property of the foulant samples and the filtered solids. Determining locations along the once-through steam generator train that include foulant precursor based on a matching of the at least one physical property between the foulant samples and the filtered solids. Installing an absorbent at locations that include the foulant precursor.

Abstract: A system and method for reducing the complexity of the reservoir simulation process is described. In more detail, an add-in for spreadsheet software program has been developed allowing a user to input minimal amount of information for a simulation, wherein the add-in exports the data as a file readable by any simulation software. Upon completion of the simulation, the add-in will retrieve the results and display them in an easy-to-interpret manner. Thus, the add-in makes the simulation process easier, robust, and user friendly.

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 to improve the fracturing monitoring, forecast hydrocarbon recoveries, or modify fracturing plans.

Abstract: The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g., in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.

Abstract: Methods and systems relate to generating steam from water that contains dissolved organic compounds. The methods mix a polymerization inhibitor with the water prior to feeding the water into a steam generator. The polymerization inhibitor limits coupling of the dissolved organics under boiler conditions to mitigate fouling issues within the boiler.
