PVT of Gas Injection

2021
This chapter introduces the PVT challenges of gas injection. First, the phase diagram of various gases, oil samples and mixtures of oil and gas are investigated. In the next part, the important PVT experiments are discussed in details. These experiments consist of CCE (constant composition expansion), DL (differential liberation), CVD (constant volume ...

Simulation studies of Gas-Injection into Gas-Condensate Reservoirs

Proceedings of SPE Latin America Petroleum Engineering Conference, 1990
ABSTRACT The effects of gas injection into two gas condensate reservoirs in eastern Venezuela were analyzed in order to establish optimum exploitation schemes. One of the reservoirs, the M3U sand, MVR-52, in the Zapatos field, is actually subjected to a pressure maintenance process. The other reservoir, the S3M sand, SG-44, in the Mapiri

Fast valve for gas injection into vacuum

Review of Scientific Instruments, 1978
A simple, fast, reliable magnetically driven gas valve for use in plasma experiments is described. The pressure rise time has been measured to be ∼1 Torr/μs at the valve opening.

Gas Gangrene from Parenteral Injection

JAMA, 1961
THE POSSIBILITY of gas gangrene is always thought of in connection with extensive contaminated wounds of the battlefield or in connection with injuries with extensive areas of devitalized tissue resulting from civil accidents. Every surgeon is acquainted with the potential dangers of these injuries, and intensive therapy is instituted at the first sign

Intraocular Gas Injection in the Pseudophakic Patient

American Journal of Ophthalmology, 1980
Two patients underwent vitrectomy with the use of intraocular gas. In one patient the cornea decompensated because of lens-cornea contact and in the second patient a surgical technique devised to protect the cornea from lens contact was used successfully.

Gas Injectivity Logging

SPE Permian Basin Oil Recovery Conference, 1959
Permian Basin Oil Recovery Conference, 7–8 May, Midland, Texas Introduction Along with the rapid development and application of re-energizing techniques designed to recover a greater percentage of the oil in place than can be produced under primary recovery methods, tools and techniques have been ...

Gas Injection for Underground Gas Storage (UGS)

2021
In this chapter, some of the key aspects of UGS as a sustainable energy supply infrastructure were reviewed. This type of gas injection is associated with the reuse of depleted oil and gas formations as a natural underground storage volumes with proved reservoir characteristics and cap rock integrity, as well as available surface facilities and wells ...

A Investigation of Fuzzy Control for Gas-injection Pressure in Gas-Assisted Injection Molding

2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007
A fuzzy control system has been developed for gas injection pressure precise control in gas-assisted injection molding. The control model was derived theoretically and its performance is improved. A fuzzy controller and its control algorithm are established.

Mechanism of Toxicity of Injected CS Gas

Nature, 1970
IN 1928 Corson and Stoughton1 prepared a number of benzylidene malononitriles, including 2-chlorobenzylidene malononitrile (CS). Although these authors were primarily concerned with the isolation and chemistry of the condensation products of malononitrile and various aldehydes, sternutatory and irritant properties on the part of some of the compounds ...

Actively controlled transverse gas injection

Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
In general the problem of feedback control for an unsteady fluid flow is nonlinear. Especially challenging is the control of mixing processes in a hot, potentially reactive environment. Because of the high temperatures present, realistic sensors can only operate mainly in cool regions, e.g., away from flames and hot exhaust regions. Consequently, there
