摘要： Methods, devices and computer-readable media for predicting hydrocarbon production rates for a subterranean formation are described. A method includes: receiving or generating, by at least one processor, well logs from data collected from at least one well in the subterranean formation; generating from the well logs a predicted production rate log for the at least one well; receiving, by the at least one processor, a field dataset for the subterranean formation, the field dataset including field data at locations in 3-dimensions of a volume of the subterranean formation; identifying the predicted production rate log for the at least one well as one or more targets, determining a transform relating the field data and the predicted rate log for the at least one well; and using the transform, generating a predicted production rate for each location of the volume of the subterranean formation.

摘要： The present invention relates to a multistage centrifugal pump design, which has the diffusers, impellors, and a shaft, inserted within a high pressure housing, such that this assembly is fully enclosed within the housing, and the housing is of sufficient strength to be suitable for safe pressure containment of the fluids being pumped. This invention describes the technical details used to reconfigure the multistage centrifugal pump design to increase the discharge pressure capabilities higher than the 6,000 psig of current designs.

摘要： A hydrocarbon production process comprising operating a first early stage hydrocarbon production process within a first communication domain with a first well pair, and operating a second early stage hydrocarbon production process within a second communication domain with a second well pair, such that an intermediate reservoir region including stranded bitumen becomes disposed between the first and second communication domains; wherein the first early stage hydrocarbon production process includes injecting a first production-initiating fluid via a first injection well of the first well pair into a first communication domain such that hydrocarbon material is mobilized and conducted to a first production well of the first well pair, and producing the received hydrocarbon material via the first production well; and wherein the second early stage hydrocarbon production process includes injecting a second production-initiating fluid via a second injection well of the second well pair into a second communication domain such that hydrocarbon material is mobilized and conducted to a second production well of the second well pair, and producing the received hydrocarbon material via the second production well; selecting a pre-selected zone within the reservoir, wherein the selecting is based upon temperature fall-off data within the first and second communication zones; and positioning a portion of an infill well within the pre-selected zone for receiving mobilized hydrocarbon material of at least the intermediate reservoir region and for producing the received hydrocarbon material.

摘要： A process for producing hydrocarbon material from a hydrocarbon reservoir through a production well that is disposed in fluid communication with an injection well via an interwell region disposed within a communication zone, comprising: maintaining pressure within the communication zone above a predetermined high pressure during a high pressure production phase, in and during at least a fraction of the high pressure production phase, supplying the first production-initiating fluid to the communication zone such that: mobilization of producible hydrocarbon material within the communication zone is effected, and such that the mobilized hydrocarbon material is conducted to the production well and produced via the production well; and at least a fraction of the supplied non-condensable gaseous material becomes dissolved within hydrocarbon material disposed within the communication zone; effecting a reduction in pressure of the communication zone from above the predetermined high pressure to below a predetermined low pressure such that at least a fraction of the dissolved non-condensable gaseous material becomes liberated from solution within the hydrocarbon material and, upon the liberation, expands and thereby at least contributes to driving the mobilized hydrocarbon material to the production well; after the effected reduction in pressure, maintaining pressure within the communication zone below the predetermined low pressure during a lower pressure production phase; effecting an increase in pressure of the communication zone from below the predetermined low pressure to above the predetermined low pressure; and repeating steps through, at least once.
