Predicting Temperature and Pressure in High-Temperature–High-Pressure Gas Wells

Petroleum Science and Technology, 2011
Abstract In this article, we give a coupled system model of differential equations concerning pressure and temperature in high-temperature–high-pressure wells according to mass, momentum, and energy balances. We present an algorithm solution model, along with the fourth-order Runge-Kutta method.

NANOMATERIALS UNDER HIGH TEMPERATURE AND HIGH PRESSURE

Modern Physics Letters B, 2010
Two different approaches to study thermal expansion and compression of nanosystems are unified, which have been treated quite independently by earlier workers. We provide the simple theoretical analysis, which demonstrates that these two approaches may be unified into a single theory, viz. one can be derived from other.

Diamond Pressure and Temperature Sensors for High-Pressure High-Temperature Applications

physica status solidi (a), 2001
A high-pressure high-temperature diamond based sensor has been developed for the use in diamond anvil cells. The electronic structure of the sensor is that of p-i-p unipolar diode with boron doped p-type regions separated by an i-region containing compensated boron acceptors.

Stability of Coronene at High Temperature and Pressure

The Journal of Physical Chemistry B, 2010
The infrared response of coronene (C(24)H(12)) under pressure and temperature conditions up to 10 GPa and 300 °C is examined in situ using a diamond anvil cell and synchrotron-source Fourier transform infrared (FTIR) spectroscopy. Coronene is a polycyclic aromatic hydrocarbon that is present in the interstellar medium and meteorites which may have ...

Evaluation of high temperature pressure sensors

Review of Scientific Instruments, 2011
It is becoming more important to measure the pressure in high temperature environments in many industrial fields. However, there is no appropriate evaluation system and compensation method for high temperature pressure sensors since most pressure standards have been established at room temperature.

High-pressure spectrometry at subzero temperatures

Analytical Biochemistry, 1982
A reliable, high-pressure bomb is described. The bomb has been designed such that it easily permits absorption and fluorescence measurements; operates between 1 bar and 8 kbar; can be used at temperatures between 30 and −40°C; can be rapidly opened and closed, thus permitting kinetic measurements; and can be easily interfaced with many commercially ...
