Paper Number: URTEC-3860644-MS
... 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...

.../month/ft) and plotted them against payzone depths and the initial GOR. These parameters were selected to understand 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...

... 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...

... 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...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3870070-MS
... 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...

Paper Number: URTEC-3718999-MS
... 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...

... 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...
