Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3866156-MS
... Abstract The paper presents 3D modeling and analysis of a series of hydraulic stimulations conducted at the DOE Utah FORGE EGS site. We have simulated Stage-1 and Stage-3 field stimulations and examined the pressure history, produced fracture geometry, and potential complexity. We use...

...-phase techniques. Introduction Devon Energy have performed 46 so-called ‘refracs’ in the Eagle Ford. A ‘refrac’, or refracturing, refers to the process of performing hydraulic fracturing again on a well that has already undergone the process in the past. It involves pumping a fluid at high pressure...

... is obtained, this model can be used to design a fracturing sequence strategy that would help replicate these results in field applications. This model could also serve as a guide for the completion design needed to recreate the positive production effect. The learnings from this study have the potential...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3864846-MS
... Abstract Proppant transport is critical in hydraulic fracturing treatments because it directly affects the effective/propped fracture geometries. While much research has been devoted to proppant transport simulation, the popularity of Eulerian-Lagrangian (E-L) models in proppant transport only...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3869278-MS
... Abstract Rock properties are assumed constant or to vary only slightly along a horizontal well placed within a correlative target. However, in the presence of folds, faults and/or fractures, the geomechanical properties can change along the well leading to skewed hydraulic fracture development...

Paper Number: URTEC-3864861-MS
... Abstract Rayleigh Frequency Shift Distributed Strain Sensing (RFS-DSS) has been demonstrated as a potential technology for characterizing fracture geometries and optimizing the completion design in unconventional reservoirs. The combination of RFS-DSS strain and pressure gauge measurements has...

... utilized the geomechanics of the infill well, a depletion analysis, limited entry modeling, and hydraulic fracture modeling to optimize the child well’s completion approach. The optimization workflow applied to the infill lateral was as follows: 1. Derive a high resolution geomechanical and pore pressure...

Paper Number: URTEC-3862595-MS
... Abstract Hydraulic fracture conductivity ( w f k f ) is a critical parameter in completion design of horizontal shale wells. Field evidence and laboratory investigations suggest that these fractures could have finite conductivity values that are influenced by the fracture closure stresses...
