Potential assessment of methane and heat production from geopressured– geothermal aquifers
美国墨西哥湾沿岸的地压型地热含水层含有大量地热能和溶解甲烷。本研究调查了盐水回注对这些含水层产生热量和甲烷的影响。首先，检查含水层性质的不确定性范围，以建立典型含水层的储层模型。然后进行敏感性分析，以找到有回注和无回注开采的有利条件，并确定了两种方案的经济标准。本研究得出结论，回注具有若干优势，如提高开采的可持续性、降低储层连通性风险以及在同一地层中处理采出的盐水。

Abstract
Geopressured–geothermal aquifers of the US Gulf Coast contain a significant amount of geothermal energy and dissolved methane. This study investigates the effect of brine reinjection on the production of heat and methane from these aquifers. First, the range of uncertainty of aquifer properties was inspected to build the reservoir model of typical aquifers. A sensitivity analysis was then performed to find favorable conditions for production with and without reinjection, and the economic criteria for both scenarios were defined. This study concludes that reinjection has several advantages, such as increasing the sustainability of production, reducing reservoir connectivity risk, and disposing of produced brine in the same formation.
