Hydraulic fracturing is widely accepted and applied to improve the gas recovery in
unconventional reservoirs. Unconventional reservoirs to be addressed here are with very …

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 …

One of the challenges of hydraulic fracturing operations is the determination of the fluid-
driven vertical fracture extent. Fracture breakout into overlaying or underlying formations …

Permanent downhole gauges (PDG) are massively installed in injection and production
wells operated in different industries such as oil and gas, geological CO2 storage, and the …

This work presents a new coupled transient wellbore/reservoir thermal analytical model,
consisting of a combined reservoir/casing/tubing system. The analytical model considers …

Hydraulic fracturing has been applied to extract gas from shale-gas reservoirs. Complicated
geological settings, such as spatial variability of the rock mass properties, local …

Downhole temperature data obtained by either temperature logging or fiber-optic cables
have been used to evaluate stimulation treatments and post-stimulation performance of …

A reliable kick simulator is a valuable tool in improving forward-looking predictions and
making correct decisions during well control operations. In this study, a transient coupled …

Hydraulic fracturing is a widely employed technique in geoengineering. It is the most
common stimulation technique to enhance reservoir permeability. Mathematical modeling of …

This work investigates the impact of temperature effect on pressure-transient measurements
made at any gauge location along a slanted wellbore completed with a production tubing …
