Paper Number: SPE-209587-PA
Published: 11 August 2022
...Micheal Oguntola; Rolf Lorentzen Summary Over the last decades, the development of different oil reservoirs with gas or chemical enhanced oil recovery (EOR) methods have been studied, and the EOR effects of the recovery methods are found to be sensitive to fluid and rock properties...

.... In general, IH is considered to be less practicable than LFH and HFH. The resistance (ohmic or conduction) heating prevails in LFH while dielectric heating prevails in HFH. Thus, the effectiveness of LFH decreases if reservoir water is overheated to generate steam. Also, the intensity of the energy released...

...Y. Wang; X. R. Zhao; K. X. Li Summary Natural gas production in the Sichuan Basin reached 30 × 10 9 m 3 in 2020, but the shortfall between this and the production goal of 50 × 10 9 m 3 in 2025 requires further exploration. The complex mineralogy and low porosity in tight carbonate reservoirs reduce...

... of this paper is that air injection into a reservoir introduces a large amount of nitrogen that is detrimental to the displacement of oil, and oil recovery yet offers few, if any, advantages. Reducing the amount of noncondensable gas (NCG) associated with the process can be done mainly in two ways—by using...

... of quantitative interpretation and leads to an updated reservoir characterization. While modeling for different possible reservoir pore fluid scenarios, the quality of the results largely depends on the accuracy of the FRM.
