Internal tamponade of the retina by means of intravitreal gas injection antedates the basics of retinal detachment repair established by Jules Gonin in the 1930s. The first use of intravitreal air injection in retinal detachment management was reported by Ohm in 1911.1 The following year Rohmer2 reported 8 cases of retinal detachment in which ...

Injection of a gas equilibrated with a liquid into the gas chromatograph
Chromatographia, 1975Applicability limits of the existing methods for the introduction of a gas equilibrated with a liquid into a gas chromatograph are discussed. A new device as well as the method of its application are described. This new device permits gas sampling from an equilibrium system without changing the concentration of the substance distributed between the two

Cryogenic Cooling by Noncondensible-Gas Injection
Science, 1965Temperature control of various cryogenic liquids in the range from their boiling points to near or below their freezing points has been achieved by injecting a noncondensing gas, helium. The process is more easily accomplished than the usual vapor-pumping technique and is applicable in the range from 15° to 300°K.

Gas Injection In The Safah Field, Oman
Proceedings of Middle East Oil Show, 1995Abstract The Safah field contains 640 million barrels of oil-in-place and 62 billion cubic feet of gas cap. The field is divided into East and West lobes. The East lobe is subdivided into Northeast and Southeast lobes based on PVT properties. The Northeast lobe contains saturated oil with gas cap and the Southeast lobe has undersaturated

Gas Return From Gas Injection Projects
Canadian International Petroleum Conference, 2008Abstract During gas injection projects (CO2 or hydrocarbon miscible/ immiscible flooding, CO2 huff 'n puff or Vapex), only a portion of the injected gases are produced back during injection periods, with additional amounts thereafter.

Rapid response gas injection technique
Review of Scientific Instruments, 1978A unique gas injection technique has been developed which has rapid response and is capable of supplying gas flowrates up to 5 kg/s at pressures of 3.45×106 N/m2. Rise times to equilibrium pressure varied from 7 to 15 ms over the operating range. The reliability, excellent repeatibility, and uniform pressure have shown the system to be superior to ...

Intermittent Injection of Gas in Gas-lift Installations
Transactions of the AIME, 1929Intermittent injection of gas in gas-lift pumping is a variation of thecommon practice in that the gas is delivered to the well for ashortperiod, called the "on time," followed by a period during which none isadmitted, called the "off time," instead of being admitted continuouslyat a constant rate or by intermittent flowing in which it is ...

Dry Gas Injection or Underground Gas Storage
2003In almost depleted oil reservoir the high gas injection can help to produce additional oil, if the process is in immiscibility or miscibility conditions. By using this reservoir for underground storage of natural gas the substantial quantities of oil can be recover.
