The main parameters of interest derived from a diagnostic fracture injection test (DFIT) are minimum in-situ stress, reservoir pressure, and permeability. The latter two can only be obtained uniquely from the transient reservoir responses, often
The problem of a plane strain hydraulic fracture propagating in a layered formation is considered. Fracture toughness, in-situ stress, and leak-off coefficient are assumed to vary by layer, while the elastic properties are kept constant
Well spacing and hydraulic fracture design optimization are among the most important challenges confronting companies operating in unconventional reservoirs. Field trials are time-consuming and expensive. Reservoir simulation and/or rate transient analysis can help guide development
This paper demonstrates how geochemical production allocations can be used to calibrate reservoir simulation models and improve the optimization of well spacing and hydraulic fracture design in unconventional assets. Geochemical analyses provide quantitative assessments of

This study describes an automated history matching and optimization workflow using an integrated hydraulic fracturing reservoir simulator and applies the workflow in four cases. The automated workflow solves a formal mathematical optimization problem to minimize
Multistage hydraulic stimulation has the potential to greatly expand the production of geothermal in the United States and worldwide. Zonal isolation and limited-entry completion overcome the problem of flow localization and generate hundreds or thousands
Parent/child interactions pose a critical challenge for oil and gas shale producers. The industry has progressed significantly in its understanding of causes and mitigation. However, important uncertainties remain. Fracture-driven interactions or more commonly, “frac hits”,
The stimulation design of hydraulically fractured wells has always pitted the engineer’s capability to maximize the fracture extent (or fracture half-length within the formation) versus the conductivity of the fracture pack generated by the deposited
We performed a modeling study calibrating a coupled “true” hydraulic fracturing and reservoir simulator to a complex set of observations from a parent-child well pad in the STACK play located in the Anadarko Basin area
In URTeC-123-2019, a group of operators and service companies presented a step-by-step procedure for interpretation of diagnostic fracture injection tests (DFITs). The procedure has now been applied on a wide variety of data across North
We performed a modeling study to compare the feasibility of three geothermal designs: a closed- loop heat exchanger, a closed-loop heat exchanger with hydraulic fractures engineered to contain thermally conductive material, and an open-loop two-well
Dr. Egor Dontsov, Chief Scientist at ResFrac gave a presentation to the ARMA HFC Warm-Up Series entitled “Morphology of Simultaneously Propagating Hydraulic Fractures.” Current hydraulic fracture designs rely heavily on inducing multiple cracks within each
