Ultrasonic Pulse Transmission

This paper contains laboratory measurements of the temperature dependence of velocities, determined by ultrasonic pulse transmission methods, in hydrocarbon liquids and rock samples saturated by the liquids. The samples discussed include 26 hydrocarbons of varying molecular weight, nine mixtures of these hydrocarbons, four heavy oils (tar), three saturated sandstones, and a saturated sand. The data provide encouragement that high‐frequency, high‐resolution seismic techniques may infer formation temperature changes, thereby detecting the progress of thermal enhanced oil recovery processes.

CoxZn1-xFe2O4 nanoparticles were prepared by chemical citrate precursor synthesis method. The Young’s modulus ‘E’ and the rigidity modulus ‘n’ of mixed cobalt-zinc ferrites have been determined by the ultrasonic pulse transmission technique at 1 MHz. The elastic modules of the ferrites were corrected to zero porosity using the formulae of Harselman and Fulrath. The observed variation of the elastic module with composition has been interpreted on the basis of binding forces between the atoms of the spinal lattice. A linear relationship between Debye temperature ØD and average sound velocity Vm has also been observed.

Abstract Oil Industry is going green and there is no solid and comprehensive publication that outlines the use of green energies and methods in oil recovery. Thus, this paper is going to close that gap. As there are more environmental restrictions especially in developed countries, inclusion of green energy methods in petroleum recovery processes is very important for the future of these reserves. We will focus on extra/heavy oil as conventional oil is simpler to produce and doesn't need EOR processes that may come with environmental footprints. The objective of this study is to investigate and outline the ‘green’ production and recovery processes of heavy oil recovery in environmentally-sensitive locations where greenhouse gas emissions, type of energy used to extract oil and gas (e.g., generation of steam using natural gas vs solar), environmental impact of surface facilities, transportation of produced oil and gas and other associated materials/chemica ls required for recovery (e.g. solvents for steam injection process) are critical for the operations as well as economics.
