McLand Resources Ltd. owns a carbonate reservoir producing a light oil with a significant amount of H2S.**Currently, the company is separating the acid gas from the produced gas, which adds additional cost to the**production operation of the pool. The company wants to look into the opportunity of re-injecting the produced**acid gas into the reservoir, which can help to simultaneously accomplish two goals: enhancing the oil recovery**efficiency and sequestering acid gas in the reservoir. One key parameter in the gas injection design is the**minimum miscibility pressure (MMP) between the acid gas and crude oil mixtures at reservoir temperature.**MMP refers to the pressure at which the injected gas will reach complete miscibility with reservoir oil,**enabling a theoretical 100% oil recovery efficiency. The research problem faced by the company is how to**accurately determine the MMP between the acid gas and crude oil in the carbonate Nisku D-2B formation. This**proposal will develop reliable and efficient computer program that can be used by Mcland to accurately**compute the MMP between acid gas and crude oil. The newly developed computer program is able to handle**acid gases with any compositions, which enables us to examine the effect of H2S concentration in the acid gas**on the gas/oil MMP.

McLand Resources Ltd.拥有一个碳酸盐储层，生产具有大量H2的轻油。**目前，该公司正在将酸性气体与生产的天然气分开，这为泳池的**生产运营增加了额外的成本。该公司希望调查将生产的**酸气体重新注入储层的机会，这可以帮助同时实现两个目标：提高油的效率**效率和隔离的酸性气体。气体注入设计中的一个关键参数是在储层温度下酸气和原油混合物之间的**最小可见性压力（MMP）。公司面临的研究问题是如何准确确定碳酸盐Nisku D-2B形成中酸气和原油之间的MMP。这个**建议将开发可靠，高效的计算机程序，Mcland可以使用，以准确地**计算酸性气和原油之间的MMP。新开发的计算机程序能够使用任何组成处理**酸性气体，这使我们能够检查H2S浓度在酸性气体**中对气体/油MMP的影响。
