Abstract The present work deals with an interpretation of well log data (gamma ray (GR), resistivity, density, and neutron) from four wells, namely P-1, P-2, P-3 P-4 in the study area Rio Del Rey basin. logs analysis indicates five potential sandstone reservoirs at two six P-4. neutron–density-GR highlight gas reservoir characterized by high resistivity crossover between neutron density. cross-...

Abstract Estimation of water saturation, S w , in shaly sandstone is an intricate process. The surface conduction clay minerals adds up to the electrolyte pore spaces, thus generating high formation conductivity that overshadows hydrocarbon effect. In each resistivity-based saturation model, key parameter factor, F which typically derived from Archie’s Law. Referring a log–log plot between fact...

The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

This paper evaluated the oil and gas potential of Cretaceous Yageliemu clastic reservoir within Yakela condensed field lying in Kuqa Depression, Tarim Basin, China. The petrophysical properties interest zones area were characterized using geophysical logs from five wells. results reveal that gas-bearing are by high resistivity, good permeability (K) effective porosity (?eff), low water saturati...

Dibenzo(a,n)pyrene, [DB(a,n)P], dibenzo(a,/)pyrene [DB(a,/)P], and seven of their benzo-ring derivatives were tested for tumorigenic activity on mouse skin and in newborn mice. In the tumor studies on mouse skin, a single topical application of 50, 200, or 600 nmol of compound was followed 7 days later by twice-weekly applications of the tumor promoter 12-O-tetradecanoylphorbol-13-acetate for 1...

At the conclusion of flooding in an oilor gas-bearing reservoir, a significant fraction of the original hydrocarbon in place remains in the swept region as trapped residual phase. In addition to the amount of trapped phase, its microscopic distribution within the pore space of a reservoir rock is important to gain a better understanding of recovery mechanisms and for the design and implementati...

An effective method of identifying and discriminating undersaturated gas accumulations remains unresolved, resulting in uncertainty hydrocarbon exploration. To address this problem, an unsupervised machine learning multi-attribute analysis is performed on 3D post-stack seismic data over several blocks within the deepwater Gulf Mexico Carnarvon Basin, offshore Australia. Results reveal that low-...

The adsorption of benzene on Co(0 0 0 1) was studied by X-ray photoelectron spectroscopy, temperature programmed desorption, low energy electron diffraction (LEED) and work function measurements. The adsorption was found to be molecular at room temperature and to saturate at a fractional coverage of 0.125 ML. With LEED a c(2 ffiffiffi 3 p 4) overlayer structure was seen. Below 220 K at high exp...

A field's hydrocarbon evaluation takes into account the productivity of reservoir bearing unit. It basically includes a thorough examination geological interpretation petrophysical parameter indices deduced from well logs. This study uses MHI and proven integrated methodologies including logs analysis, computing, to evaluate Sapele-field with objective establishing its fluid types saturations. ...

Phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of unsaturated neutral lipid, dioleoylphosphatidylcholine (DOPC), saturated neutral lipid, dipalmitoylphosphatidylcholine (DPPC), unsaturated charged lipid, d...
