Paper presented at the SPE Western Regional Meeting, April 20–22, 2021
Paper Number: SPE-200873-MS
... Abstract Despite the great potential of unconventional hydrocarbons, the primary recovery factor from such reservoirs remain low. The gas-injection enhanced oil recovery (EOR) has been proved to be a promising approach by both laboratory and simulation studies. However, the fluid model for...

Paper Number: SPE-200871-MS
... Abstract Horizontal well technology is one of the major improvements in reservoir stimulation. Planning and execution are the key elements to drill horizontal wells successfully, especially through depleted formations. As the reservoir has been producing for a long time, pore pressure declines...

Paper Number: SPE-195277-MS
... Abstract Fracturing activities had been a big success in the petroleum community, particularly when it came to the development of unconventional resources such as shale gas, however, as the production rate went down over time, secondary fracturing was necessary to restimulate the reservoir, how...

Paper Number: SPE-195263-MS
... Abstract Heat generation in the reservoir by means of electromagnetic wave stimulation offers innate advantage with efficient energy introduction. Transmissibility of heavy oil and bitumen are predicated on decreased viscosity through temperature rise, which makes microwave heating a plausible...

Paper Number: SPE-195257-MS
.... Although, polymer flooding has attracted attention and has become a promising EOR technique in heavy oil reservoirs due to the extensive application of horizontal wells and advancement of polymer flooding technology, no field tests have been performed to date in Alaska's underdeveloped heavy oil reservoirs...
