Reservoir stimulation and artificial lift are the two main activities of the production engineer
in the petroleum and related industries. The main purpose of stimulation is to enhance the …

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 …

A comprehensive analysis of all publicly available data and reports was conducted to
evaluate impact to Underground Sources of Drinking Water (USDWs) as a result of acid …

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 …

Testing unconventional reservoirs, particularly hydrocarbon-bearing shale formations,
presents considerable challenges. This paper reviews those challenges and their effects on …

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) …

This paper provides a framework for adding after-closure fracturing-pressure analysis to the
pre-treatment calibration-testing sequence that defines fracture geometry and fluid loss …

Fluid loss into reservoir rocks during hydraulic fracturing is modelled via a poro-elastoplastic
pressure diffusion equation in which the total compressibility is a sum of fluid, rock and pore …

Over the past two decades, Diagnostic Fracture Injection Tests (DFIT) or Injection-Fall-off
Fracture Calibration Tests have evolved into a commonly used and reliable technique to …

As an important part in the process of hydraulic fracturing, fracturing fluid flowback after
fracturing will directly affect the productivity of the fractured wells. It is of great significance to …
