... Abstract Currently, the most effective way to extract resources from shale reservoirs is through the use of multi-stage fracturing of horizontal wells. However, the process of flowback after fracturing can affect the extent of damage done by the fracturing fluid to the formation and fracture...

... in the cased hole has been shown to precisely replicate open hole THG, unless reservoir conditions have changed. Over a period of hours, variations in THG buildup and decay rates characterize fluid properties and formation permeability as condensate forms and vaporizes. Flow unit boundaries appear...

... Abstract Gas injection performance may vary significantly depending on the reservoir fluid, rock, and natural-fracture characteristics. Hence, well design and injection strategy optimization is essential to maximize the recovery. While the reliability of the optimization results is contingent...

... Abstract Hydrogen storage is a step forward to achieving low-carbon energy goals due to its potential to help with the intermittency problems of the renewable energy sources. Ample capacity of geologic reservoirs, such as aquifers, depleted reservoirs, and salt caverns, provide an attractive...

... Abstract Carbon capture and storage in depleted shale gas reservoirs offer an opportunity to utilize CO 2 for enhanced gas recovery while providing access to fossil fuels. To evaluate CO 2 sequestration coupled with enhanced gas recovery (CO 2 -EGR-CCUS), we have developed a model...

... Abstract Natural fractures are important for oil and gas production in tight reservoirs that are usually characterized by ultralow matrix porosity and permeability. Natural fractures can be characterized by core sample analysis, image logs, production data, and other data sets; however, some...

... the production performance of the shale oil plays in relation to geologic and reservoir conditions. Overall, oil production per depth follows a bell-shaped profile that can be divided into three zones. The upper tail at depths of 400-6000 ft is too shallow for oil generation, and we interpret oil accumulations...

... closely tied to the business scale and success. One first order driver of financial results is the tradeoff between well density and completions intensity which involves assumptions about producing reservoir volume and completed reservoir volume. The complexity of unconventional reservoirs prevents...

... Abstract Nowadays, the unconventional shale-oil and shale-gas reservoirs are developed by fracking technology, using sand as proppant particles in order to improve the hydraulic fractures conductivity. The use of sand as proppant particles has been conceived for a conventional sandstone...

... into the depleted formation in Avalon shale. A pilot project was executed, determining the injectivity of the well, allocation method verification and operability. A dual-tank model was built with a stimulated reservoir volume (SRV) and matrix volume based on rate transient analysis (RTA). The transmissibility...

... Abstract Marked by complex physics in fluid flow through fractured porous media, reservoir modeling for unconventional reservoirs is often deemed a challenging task for production forecast and optimization at field scale. Traditional methods such as decline curve analysis (DCA), rate transient...

... Abstract Estimation of original hydrocarbons in place is a fundamental responsibility of a practicing reservoir engineer and is essential for constraining production forecasts and reserves estimates within physically reasonable bounds. In traditional reservoir engineering, most non-empirical...

... Abstract The objective of this study was to investigate the trend of increasing water cuts in Permian Basin unconventional reservoirs and understand its relationship with development and production strategies, which have evolved greatly in the past 10 years. In many Permian Basin...

... are compared with conventional methods such as decline curve analysis (DCA) and reservoir simulation through error analysis techniques. Introduction The estimated ultimate recovery (EUR) has crucial relevance in unconventional reservoirs, as it incorporates the cash inflow used for net present value (NPV...

... Abstract Water disposal is a critical component of daily operations in unconventional and some conventional oil and gas fields. Holistic management of disposal reservoirs requires assessment of the fillup volume to drive reservoir management. Traditional material balance, pressure transient...

... in the primary huff ‘n’ puff (HnP) well using gas injection rates of 17 MMscfd. The production performance of offset wells strongly depended on the stimulated reservoir volume (SRV) around these wells. An offset well with a large SRV close to the HnP well could also have a maximum of 58% incremental oil recovery...

... Abstract Gas injection is one of the most widely used processes in the oil industry and is considered a promising enhanced oil recovery (EOR) method. Factors such as the injected gas type, minimum miscibility pressure (MMP) of injected gas, reservoir and fluid characterization can all...
