With the increasingly wide use of hydraulic fracturing in the petroleum industry, it is essential
to accurately predict the behavior of fracture propagations based on the understanding of …

In this paper, we present the fracture-compliance method, a technique for estimating the
closure pressure from diagnostic fracture-injection tests (DFITs). The method is based on the …

This paper summarizes findings from a one-year study sponsored by seven operators and
service companies to investigate interpretation of diagnostic fracture injection tests (DFIT's) …

Abstract 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 …

The prevailing approach for hydraulic-fracture modeling relies on linear-elastic fracture
mechanics (LEFM). Generally, LEFM that uses stress-intensity factor at the fracture tip gives …

Fracture injection/shut-in tests are commonly used to measure the state of stress in the
subsurface. Injection creates a hydraulic fracture (or in some cases, opens a preexisting …

The fracture injection fall-off test is a common technique for determining rock properties and
fracture closure pressure. Conventional methods for analyzing DFIT are formulated based …

Estimation of in-situ stresses has significant applications in earth sciences and subsurface
engineering, such as fault zone studies, underground CO 2 sequestration, nuclear waste …

Estimating reservoir-flow capacity is crucial for production estimation, hydraulic-fracturing
design, and field development. Laboratory experiments can be used to measure the …

Since the injection-falloff fracture calibration test is generally accepted as a reliable way to
obtain several key formation parameters, it is one of the essential parts of hydraulic …
