Gas-lift is one of the artificial methods in which gas is injected down the production casing–tubing annulus and enters the production tubing through a number of gas-lift valves. During the production of a gas-lift well, the injected compressed gas might

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

PHASE BEHAVIOR OF GAS-CONDENSATE FLUIDS DURING WELL TESTING
Hydrodynamic studies in gas-condensate wells allow determining the features of fluids flow in the gas condensate reservoir by build-up curves. A variation in the shape of the build-up curve may reflect a behavior of fluids in the reservoir, that is the ...

Influence of Hydrate Formation and Concentration of Salts on the Corrosion of Steel 20 Pipelines
One of the ways to increase natural gas production is to conserve and/or intensify existing wells with their subsequent development. They are characterized by a high content of highly mineralized water, which leads to an increased risk of hydrate ...

Propane from the North Slope: Could It Reduce Energy Costs in the Interior? [PDF]
Could propane from the North Slope cut energy costs in Fairbanks and other Interior communities that heat buildings or generate electricity with fuel oil or naphtha? The Alaska Natural Gas Development Authority (ANGDA) thinks it could. That’s because

This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

CHANGES OF THE NATURAL ELECTRICAL POTENTIAL OF STEEL IN THE STRESS-STRAIN STATE
The experimental investigations of steel samples under the influence of the bending load were conducted. It is demonstrated that in the event of the steel stress-strain state occurrence, its natural electric potential changes.
