... and their reliability (failures due to flutter, plate impact). Abstract Gas lift is the preferred method of artificial lift of many operators in the Delaware Basin due to high gas/oil ratio's (GOR). The volumes of produced gas have a high liquid yield creating challenges for gas lift compression and surface...

... separation and treating overboard discharge liquid bin accumulator Facilities Sand Management All oil and gas wells produce sand, and therefore, all production facilities must be capable of managing sand in flow streams. Sand Control attempts to exclude solid particles from the well flow via...

... Abstract In the implementation of gas lift, understanding flow behavior in highly-deviated well is critical in avoiding production loss due to liquid fallback and blockage, even in highly-productive reservoir. In this work, we utilize Computational Fluid Dynamics (CFD) to optimize gas lift...

... Abstract Experiments were performed to investigate the physics behind intermittent production and liquid loading, using a setup containing a reservoir model coupled to a vertical production tubing. In the experiments both gas and liquid are injected into the reservoir, which is a container...

... Abstract As the reservoir pressure drops in the vicinities of horizontal gas wells drilled in tight reservoirs, the produced gas loses its ability to drag liquids to surface. This results in the accumulation of liquid in the bottom of the well. Since conventional artificial lift methods fail...

Two liquid columns with a large viscosity contrast and separated by an interface are circulated in the annulus at a constant wellhead...

... Abstract This paper presents a systematic study of the performance of a family of "dry liquid" emulsifiers prepared via a novel "liquid-to-powder" process based on absorption of liquid by special types of synthetic amorphous silicas. The ability to use chemicals in solid form improves safety...

... (sulfonate series) as well as new generation chemicals (nanofluids, ionic liquids) were tested for this purpose. After testing and screening effective chemicals without pre-solvent injection, the same chemicals were used to retrieve the solvent and recovery additional oil for pre-solvent injected systems...

... Abstract The industry push towards compact, subsea gas-liquid separators has been pronounced in recent years. There are, however, associated risks in decreasing the size of separators. In particular, if the hydrocarbon liquid is supersaturated with gas and requires significant time to evolve...

.... The observed laboratory variations in trapped gas saturation represent one of the main uncertainties in the recoverable reserves of the field. Two laboratory methods for estimating this quantity are compared: one is the classic test in which core samples are immersed in a liquid and undergo a spontaneous...

...-liquid separation is performed. Relatively simple in design, this tank consists of only one element of internal diameter 500 millimetres and a height of 3 meters. The lower base is conical so as to be representative of an actual tank, in particular to avoid the possible build-up of sand. The tank...

The second, using recombined Well-G fluid, was designed to understand the effect of different separator temperature and pressure conditions. Work was carried out on a recombined sample of separator liquid and gas from...

This phenomenon is called liquid banking and can result in moderate to severe productivity declines 2 - 3 . To simulate the effect of banking in numerical...

...Global Energy Market Model (GEM) The model presented in this paper leads to what we are calling the "2030 1/3 forecast". It indicates that global energy needs will be met by approximately 1/3 of liquids, 1/3 of solids and 1/3 of gases by 2030. Although the model can be used for forecasting far...

It demonstrates clearly that the maximum recovery will be obtained using a pump rather than gas lift, everything else being equal. Separating the gas and liquid downhole gives a lower...
