Temperature-resistant and salt-tolerant mixed surfactant system for EOR in the Tahe Oilfield [PDF]
Petroleum Science, 2021 AbstractA new temperature-resistant and salt-tolerant mixed surfactant system (referred to as the SS system) for enhancing oil recovery at the Tahe Oilfield (Xinjiang, China) was evaluated. Based on the analysis of the crude oil, the formation water and rock components in the Tahe Oilfield, the long-term thermal stability, salt tolerance and the ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 The pore sizes in tight reservoirs are nanopores, where the phase behavior deviates significantly from that of bulk fluids in conventional reservoirs. The phase behavior for fluids in tight reservoirs is essential for a better understanding of the mechanics of fluid flow.

Geofluids, Volume 2021, Issue 1, 2021., 2021 Carbonate fracture‐vuggy reservoirs are one of the hot spots in oil and gas exploration and development. However, it is extremely difficult to describe the internal spatial structure of the fracture‐vuggy unit and understand the interwell connection relationship.

Relationship between Faults and Hydrocarbon Distribution in Tahe Oilfield Southeast Slope [PDF]
Proceedings of the 2015 6th International Conference on Manufacturing Science and Engineering, 2015 Fault in Tahe Oilfield southeast slope has a positive meaning for more oil and gas reservoir, it can be divided into eight groups. Three of them have significant control action for the gas-water including north-south, NNE and NEE. They have closely related with fracture and karst reservoir seam holes, karst cave reservoirs and fractured reservoirs ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 A large amount of light crude oils have been found within 4000 to 7000 m deep strata of Cambrian, Ordovician, and Silurian reservoirs in the Tarim Basin, NW China. To enhance the understanding of parental materials of deep oils, a set of high‐quality source rocks from the Yuertusi Formation in well Luntan 1 (maximum drilling depth of 8882 m) was ...
