The Impact

Abstract Unconvnetional reservoirs are predominantly consisted of nanoscale pores. The strong confinement effect within nanopores imposes significant deviations to the confined fluid phase behavior. Minimum miscibility pressure (MMP) in unconventional reservoirs, as a parameter highly related to the phase behavior of confined fluids, is inevitably affected by the nanoscale confinement. The objective of this work is to investigate the impact of nanoscale confinement on MMP of unconventional reservoir fluids and to recognize a reliable theoretical approach to determine the MMP values in unconventional reservoirs. A modified Peng-Robinson equation of state (PR EOS) applicable for confined fluid characterization is applied to perform the EOS simulation of the vanishing interfacial tension (VIT) experiments. The MMP of a binary mixture at bulk and 50 nm are obtained via the VIT simulation. Meanwhile, the multiple mixing cell (MMC) algorithm coupled with the modified PR EOS is applied to compute the MMP for the same binary system. Comparison of the calculated results to the experimental values recognize that the MMC approach has higher accuracy in determining the MMP of confined fluid systems. Moreover, this approach is then applied to predict the MMP values of both Bakken and Eagle Ford oil at different pore sizes with various injected gases. Results demonstrate that the nanoscale confinement causes drastic suppression to the MMP of unconventional reservoir fluids and the suppression rate increases with decreasing pore size. The drastic suppression of MMP is highly favorable for the miscible gas injection EOR in unconventional reservoirs.

Dual Objectives

This paper describes a gas re-injection project designed with the dual objectives of emissions reduction and enhanced oil recovery in an Australian offshore oil field. While gas injection for enhancing oil recovery is common oilfield practice, there are fewer projects that look exclusively at greenhouse gas (GHG) control (either by sequestration or emission reduction), although there is increasing environmental awareness in the industry on the benefits of doing so. The predominant contribution to total GHG CO2-e emissions is from flaring. Significant reductions in flaring have been achieved since completion of commissioning of injection. Flare CO2 emissions at the beginning of 2000 (February-March) reduced from approximately 163,000 tonnes per month to an average of approximately 26,000 tonnes per month over the remainder of 2000, and to 9,800 tonnes per month, over the first half of 2001. GHG efficiency, evident in the ratio of GHGs emitted per tonne of hydrocarbon produced, reduced from approximately 0.4 tonnes CO2-e per tonne of total hydrocarbon produced before injection to 0.08 after injection over the remainder of 2000, and to 0.06 over the first half of 2001. Miscible displacement is expected to add around 6 million barrels to ultimate recovery from the Corallina reservoir. The use of stored gas as a fuel is expected to achieve significant reductions in operational expenditure later in field life.
