GMI, with support from the U.S. Environmental Protection Agency (EPA), worked with a partner in Kazakhstan to obtain data on associated gas availability and content to assess the opportunity to mitigate methane and reduce flaring at the Mangystau oilfield in southwest Kazakhstan. The prefeasibility study investigated the potential to monetize the stranded associated gas in the Mangystau oilfield by utilizing modular, small-scale processing technologies to produce marketable liquid hydrocarbon commodities such as methanol, syn-diesel, oil, or others. The report includes the results of the prefeasibility assessment of the range of practical mitigation options and recommendations for an optimum solution.
