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 ...

Note on Gas Chromatographic Injection
Nature, 1964IN the course of investigations of the accurate determination of gas chromatographic retention times, several causes of errors in these measurements have been examined; this communication is concerned with the errors which may be due to the finite concentration of any one component observed, even when the isotherms are practically linear for that ...

Simulation studies of Gas-Injection into Gas-Condensate Reservoirs
Proceedings of SPE Latin America Petroleum Engineering Conference, 1990ABSTRACT 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, 1978A 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.

Intraocular Gas Injection in the Pseudophakic Patient
American Journal of Ophthalmology, 1980Two 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.

A Investigation of Fuzzy Control for Gas-injection Pressure in Gas-Assisted Injection Molding
2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007A 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.

Gas Gangrene from Parenteral Injection
JAMA, 1961THE 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

Actively controlled transverse gas injection
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002In 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
