Tuha oilfield energy storage project

Does energy storage fracturing work in low permeability oil fields?

Jilin Oilfield has conducted experiments using energy storage fracturing technology in six low permeability oil fields, with an average cumulative increase of 3.64 × 10 5 kg of oil per well during the validity period, which is 2.7 times that of conventional fracturing, achieving significant fracturing effects .

Can energy storage fracturing be used in China's oilfields?

Consequently, in China's Tuha Oilfield , Huabei Oilfield , and Jilin Oilfield [70, 71], scholars have developed energy storage fracturing technology by combining formation energy supplement with fracturing reservoir reconstruction to address this issue.

Does Shuang 229 block integrate thermal oil recovery in CCUs-EOR mode?

Shuang 229 block integrated thermal oil recovery in CCUS-EOR mode. The combustion gas generated by the in-situ combustion employed at Shuguang block was processed and transported to Shuang 229 block by pipelines for the purpose of EOR.

How does fluid distribution affect CO2 storage in oil reservoirs?

The fluid distribution in oil reservoirs results in a slight difference between the mechanisms of CO 2 storage in oil reservoirs and that in saline aquifers, which has been extensively discussed in the literature , . As a result, it is necessary to discuss the mechanisms of CO 2 storage in oil reservoirs.

Does tertiary waterflooding improve oil recovery?

As depicted in Fig. 4, secondary and tertiary CWI resulted in 24 % and 20 % higher oil recovery, respectively, compared to conventional waterflooding. Approximately 22 % and 32 % of the total injected CO 2 were stored in the cores, primarily due to solubility trapping in the residual oil.
