investment in oil and gas upstream activities is very important for the exploration and development of oil and gas fields. different and various laws and regulations deal with the investment in upstream operations. by reviewing these various laws and regulations, this research paper tries to discuss to what extent these laws and regulations have created legal confident for foreign investment up...

This work presents characterization data and viscosity of 34 secondary vacuum gas oils (H-Oil oils, visbreaker fluid catalytic cracking slurry oils) with aromatic content reaching up to 100 wt.%. Inter-criteria analysis was employed define the VGO characteristic parameters which have an effect on viscosity. Seven published empirical models predict were examined for their prediction ability. The...

Turquoise hydrogen refers to produced through a fossil-fuel-based process in which carbon is separated into solid and no dioxide produced. In this study, dodecane was selected as simulated oil for waste plastic pyrolysis recovery oil, the turquoise production characteristics thermal cracking reaction using an arc plasma torch were investigated. The stably discharged at 2 4 kW. Hydrogen gas anal...

For the modeling and simulation of oil recovery from naturally fractured reservoirs during the gas injection process, an accurate value of the molecular diffusion coefficient (MDC) of gases from a gas filled fracture into the oil matrix is essential. During the injection of miscible fluids with oil, transport of the injectant and oil are controlled by fracture and matrix properties. Diffusion i...

China-Myanmar oil & gas pipeline project covers 7,676 miles in all. The project met with complex geological conditions, construction types along the line, and long-distance oil & gas parallel laying pipeline. Because the pipeline layout and the construction are more complicated, it is necessary to make the stress analysis of oil & gas parallel laying pipeline traversing tunnels. Software CAESAR...

The processes of nucleation, bubble growth and finally the creation of connected gas during the pressure draw-down in an oil reservoir are discussed. From these mechanisms, possible descriptions of foamy oil production appear. One of these mechanisms is the creation of bubbles, small compared to pore sizes, which move with the oil phase and which push the oil out of the reservoir. If this mecha...

The coexistence of numerous Mississippi Valley-type (MVT) Pb-Zn deposits and oil/gas reservoirs in the world demonstrates that a close genetic link between them. northern Yunnan–Guizhou depression (NYGD) is tectonic unit containing Pb–Zn deposits, paleo-oil shale gas. However, previous studies on relationship hydrocarbon accumulation mineralization have been ignored. Maoping deposit large-sized...

Comprehensive two-dimensional gas chromatography (GC×GC)was used to investigate theBouchard 120 oil spill. The latter occurred on April 25, 2003, when the barge Bouchard 120 spilled ∼375,000 liters of No. 6 fuel oil into Buzzards Bay, Massachusetts. In order to gain a better understanding of the natural processes affecting the fate of the spilled product, we collected and analyzed oil-covered r...

Foam mobility control and novel oil displacement mechanisms were observed in a microfluidic device representing a porous media system with layered permeability. Foam was pre-generated using a flow-focusing microfluidic device and injected into an oil-wet, oil-saturated 2-D PDMS microfluidic device. The device is designed with a central fracture flanked by high-permeability and low-permeability ...
