Paper presented at the SPE Eastern Regional Meeting, October 8–10, 2024
Paper Number: SPE-221370-MS
... polymers can maintain viscosity and stability at temperatures exceeding 350°F (177°C), and new drilling fluids have been successfully tested in geothermal wells with bottom hole temperatures up to 400°F (204°C). Moreover, hydraulic fracturing techniques, widely used in the oil and gas industry, are being...

... in the evaluation of which completion technique is most effective for large volume fluid injection. Hall Plots were generated to compare openhole and cased hole SWIWs, but will not be the focus of this paper. A review of physical reservoir properties and fracture modeling were used to estimate three-dimensional...

Paper Number: SPE-215913-MS
... Abstract Economic optimal recovery of hydrocarbons from unconventional reservoirs requires consistent and sufficient stimulation energy across an entire drill spacing unit (DSU), both along laterals and between them. This necessitates an understanding of how and why fractures propagate away...

... The in-house pseudo-3-dimension fracture simulator is based on the PKN (Perkins-Kern-Nordgren) model. The detailed numerical workflow is similar to that of the 2D numerical fracture model discussed in the previously published papers ( Gu and Mohanty 2013 ). In this study, the 2D model is extended...

... such that the induced hydraulic fractures grow parallel to the maximum horizontal stress during completion ( Zinn et al., 2011 ). As such, collection and interpretation of image logs from a representative set of pilot holes for determination of horizontal stress orientation are now a typical procedure in the early...

... Abstract Low injected fracturing fluid recovery has been an issue during flowback period that is highly impacted by the fracture closure behavior. Although existing flowback models consider fracture closure volumetrically, they do not represent the true situation of non-uniform fracture closure...

... dimensional formulation is considered here for the application of matrix-fracture cross mass transfer. Note that the rock matrix can also consist of different regions with different average pore sizes. Both convection and molecular diffusion terms are included in the mass balance equations, while different...
