Underground gas

The intelligent magnetic pig KOD-4M-1420 was developed and passed trials. This system is designed to provide corrosion and cracks detection in the operating underground gas pipelines at the distances up to 150 km. 

Most of the liquid fuels in use today are obtained from crude oil, also called petroleum, a brownish-green to black colored viscous oil found under the crust of the Earth either on shore or off shore. This oil either flows out by itself due to underground gas or hydrostatic pressure, or it is mechanically pumped out. Petroleum almost always occurs along with gas called natural gas. When the oil well contains both oil and gas it is called a wet well, and when it contains only gas it is called a dry well. 

At present there is still excess electrical capacity in the U.S.. In addition, the low price of gas permits the economic construction of new gas turbine electrical plants. But new gas plants, and methane leaking from underground gas production facilities and... 

Another group of surveys has focused on the direct modeling of some effective transport phenomena which are essential for predicting parameters that have an important role in underground gas sequestration process such as diffusivity and convection. Azin et al., in 2013, have conducted study regarding correct measurement of diffusivity coefficient [114]. 

Diverter - The part of the bell nipple at the top of a marine riser, that controls the flow of gas or other fluids that may enter the wellbore under pressure, before the BOP stack has be set in place. It is used when drilling through shallow underground gas zones for diverting gas kicks in deep high pressure zones.

Natural gas is a hydrocarbon of low molecular weight consisting of about 85% methane (CH ), which is recovered as an underground gas in areas where petroleum is found. It is also economically produced by conversion of crude oil to gas. Possible future sources of a hydro-gen-based fuel are large frozen methane deposits recently found on ocean bottoms. 

Four states—Michigan, Pennsylvania, Illinois, and Ohio—have half of the total underground gas storage pools in the United States, with a total... 

In order to avoid expected interruptions and obstacles special precautions are made for a) underground gas storage capacity, b) modem small scale technologies for LNG production and utilization, c) strategic planning of water reservoirs and liquid fuels reserves. 

The Underground gas storage facilities at Karadagh and Kalmas in summer. 

In winter, gas is supplied to the Baku and Absheron consumers and to the Ali Bayramli power plant from the underground gas storage facilities. Some of the gas supplied from storage in winter period is imported gas, which is put into storage in summer.

Theses developments require the creation of an infrastructure capable of dealing with the problem of fluctuating demand versus rather constant supply flows while still guaranteeing supply security. Among the solutions which can be considered, underground gas storage (UGS) facilities seem to be one of the most reliable and cheapest additional facilities. 

UGS, which is a relatively recent technique, has been developing rapidly and is now an essential part of the gas chain. Stimulated by the changes taking place on the gas market, underground gas storage will continue to be developed in the next years.

Based on the reservoir simulation the overall conclusion is that the Ninotsminda oil field can technically be used as an underground gas storage facility. The developed reservoir simulation model is able to match reasonably well with the historically observed oil and gas production, and with average reservoir pressure for the Ninotsminda oil field.
