... Abstract In past studies, changes in fluid pressure in natural fractures (planes of weakness) have been ignored for the interaction of hydraulic and natural fractures. To overcome these limitations, in this paper we develop a method to simulate the growth of hydraulic fractures...

... 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...

... Abstract Numerical simulation of hydraulic fracture propagation is increasingly used to evaluate the effect of various mechanistic aspects (e.g., inclusion of poroelastic effects, proppant transport, etc.), and of several variables, on the result of a stimulation operation at varying scales...

... 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...

... operators to tailor enhanced oil recovery (EOR) methods for UR (e.g., Thakur 2019). These can be summarized into three broad categories (e.g., Alfarge et al., 2017): 1. Mixing chemical surfactants with hydraulic fracturing fluids to induce wettability alterations of intermediate- to oil-wet reservoirs...

... Abstract The Triassic Chang 8 tight sand reservoir in Xifeng block of the Ordos Basin has low permeability, therefore hydraulic fracturing and subsequently water flooding were performed during the development phase. Water breakthrough was encountered for many wells after a short period of oil...

... This paper will first give an overview of the DJ basin and of the subsurface properties of the area of interest. After presenting the 3D earth modeling workflow, we will show the single well hydraulic fracture modeling exercise before covering the multi-well fracture model and production history matching...

... the injection and/or shut-in phases of a mini-frac test. However, S 3 interpreted from different methods is often inconsistent with each other and could result in large uncertainty in determining net pressure. This paper presents a series of small-scale laboratory hydraulic fracturing experiments conducted...

... Abstract To optimize hydrocarbon production from unconventional reservoirs, operators have been improving completion designs and well spacing for decades. Well spacing and completion design optimization is a challenging task due to the unknown hydraulic fracture geometry and the uncertainty...

... away from well-control is challenging, particularly their influence on the growth of hydraulic fractures. The key objectives of this paper are the following: (a) How to include a population of natural fractures in hydraulic fracture models (b) What are the fundamental controls governing the interaction...

... Abstract Unconventional well frac hits, also known as Frac Driven Interactions (FDI), are well-to-well communication events initiated by hydraulic fracturing of an offset well. While some wells show production uplifts after a frac hit, many wells experience production degradation or complete...

... horizontal wells that were drilled and produced from 2011 through 2022, with two (2) of them being recently refractured in 2022. The calibration effort consisted of matching the daily rates (oil, gas, and water) and bottomhole pressure values of all the wells, during the hydraulic fracturing, flow back...

... Abstract Hydraulic fracturing in unconventionals ascribes to "fractures should be perpendicular to the axis of least stress". First published in 1957 by, this theory stands the test of time. They determined this by injecting a plaster slurry into "ordinary gelatine" (homogeneous medium) under...

... Abstract Hydraulic fracture stimulation is generally designed and analyzed on the assumption that stimulation produces a single planar tension fracture. Microseismic monitoring and breakthroughs to offset wells have long provided evidence of the existence of reactivated natural fractures...

... Abstract Three single-cluster hydraulic fracture stages were pumped at the Frontier Observatory for Research in Geothermal Energy (FORGE) site in Milford, Utah. Our goal was to develop a robust model to accurately represent the formation of fracture networks in this naturally fractured...

The model enables users to characterize different properties in multiple regions (matrix, propped hydraulic fracture, unpropped hydraulic fracture...

... with extremely low permeability is attributed to horizontal drilling and hydraulic fracturing. Successful applications in the shale gas proved the feasible value of the multistage hydraulically fractured well. The well productivity is driven by the stimulation effectiveness to create a large matrix/fracture...

... Abstract Fracture extension replications from commercially available software can provide granular hydraulic fracture properties resulting from material and energy balances in a grid-based environment. The results from purely physics-based platforms are largely accepted as the most accurate...
