... Abstract Horizontal drilling technologies have evolved during last decades making possible wells with thousands of feet of long horizontal sections. These drilling advancements have contributed to drill more intricate multilaterals wells to ensure a thorough contact with the reservoir. In terms...

... by using readily available equipment and sources of water and gas in a water alternating-gas (WAG) scheme. Oil recovery mechanisms include raising reservoir pressure above the minimum miscibility pressure and improving gas conformance to displace incremental oil in a scalable process. Numerical models...

... dioxide as a novel conformance control strategy in reservoirs that experience poor sweep efficiency due to heterogeneity. These two chemical agents react to precipitate solid calcium carbonate, potentially blocking already-swept pores and directing injected fluids to unswept regions of the reservoir...

..., it is time-consuming, inconvenient, and complicated. This work aims to enhance the prediction efficiency and accuracy of MMP between CO 2 and crude oil under reservoir conditions by improved and integrated machine-learning approaches. A novel method is proposed to improve the forecasting accuracy...

... Abstract Most oil and gas wells are stimulated. In unconventional reservoirs, proppant fracturing is the preferred stimulation technique. However, in higher permeability conventional carbonate reservoirs, matrix acidizing and acid fracturing can also result in stimulated wells, usually...

... Abstract Depleted gas reservoirs are suggested as a suitable choice for the seasonal storage and utilization of hydrogen (H 2 ) with the presence of surface infrastructure, large storage capacity, and available history data. However, hydrogen mixing with in-situ natural gas and cushion gas...

... Abstract Deepwater developments in the Gulf of Mexico have historically focused on high kH (∼10,000 – 100,000 md-ft) Miocene reservoirs. Production from a single sand in these prolific reservoirs has been sufficient to justify the high costs of a deepwater well. In the last decade, there have...
