Abstract Although gas-lift is an established technology for improving the performances of oil production wells, simplicity, robustness and accuracy models remain to be fully resolved. As improvement on traditional practice, this paper proposes a new approach modelling performance gas-lifted wells at steady-state conditions. The conceptual framework splits wellbore into two segments. segments ar...

Oil and gas well delivery involves the execution of projects, with attention to safety, design specification, desired objectives, planned time, agreed budget. These projects involve drilling, completion, work-over, decommissioning/restoration (also known as abandonment) activities.
 Performance, respect oil process, is result comparing actual versus plan above-mentioned indicators. This me...

Glycerol solutions were vaporized and reacted over ceria catalysts with different morphologies to investigate the relationship of product distribution surface facets exposed, particularly, yield bio-renewable methanol. Ceria was prepared cubic, rodlike, polyhedral via hydrothermal synthesis by altering concentration precipitating agent or temperature. conversion found be low a cubic morphology,...

Orphaned oil and gas wells are abandoned for which the cost of environmental impacts usually falls on governments general public. Government agencies responsible well plugging often face funding shortfalls many orphaned remain unplugged. To address this support natural industry, federal already spending, or considering billions dollars to plug wells. Here, we analyze data United States Canada i...

One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...

in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...

The mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. A gas-induced External Airlift Loop Bioreactor (EALB), a forced-liquid Vertical Tubular Loop Bioreactor (VTLB) and a forced-liquid Horizontal Tubular Loop Bioreactor (HTLB) were used for mixing studies as well as biomass production from natural gas. The effect of design parameters, riser to downcomer cro...

The effect of poroelastic properties the shale matrix on gas storage and transport mechanisms has gained significant attention, especially during history-matching hydrocarbon production forecasting in unconventional reservoirs. common oil industry practice reservoir simulation is extension conventional that ignores dynamic behavior porosity permeability as a function effective net stress.
