Ultralow-temperature fluids (such as liquid nitrogen, liquid CO2) are novel waterless
fracturing technologies designed for dry, water-sensitive reservoirs. Due to their ultralow …

Productions from oil and gas reservoirs can induce significant pressure and temperature
changes at the wellbore. The temperature signal is sensitive to reservoir properties and …

Significant fluid-property variation can be induced with pressure and temperature dynamics
in the reservoir associated with oil production. The existing analytical solutions for …

Multilayer systems are widely encountered in underground hydrocarbon reservoirs. To
obtain accurate multilayer properties and understand the flow behavior in a multilayer …

Grade of oil shale and reaction parameters of in-situ pyrolysis must be identified for the
prediction of productivity before actual heating and production. Identification of oil shale …

Multistage hydraulic fracturing of horizontal wells is one of the most effective techniques for
developing unconventional reservoirs. Understanding the amount and location of hydraulic …

Waterflooding is a widely used technique for developing unconventional reservoirs. Long-
term waterflooding can lead to the formation of multiple induced fractures. Accurately …

Temperature can be used to detect the leakage of fluids from the CO2 storage zone. CO2
leakage is accompanied by temperature cooling due to the Joule‐Thomson effect. We …

The significant pressure and temperature signals at wellbores associated with hydrocarbon
production can be very useful for reservoir characterization and production analysis …

Combined perforation and well test system is commonly used in oil and gas fields,
especially in reservoirs with low energy and transmissibility. For the conventional inversion …
