An independent corporation that buys natural gas from many producers, re-sells it to buyers, and obtains the necessary pipeline transportation capacity and removal/export permits and licenses. Marketers usually sell to buyers that individually require large amounts of natural gas, such as local distribution companies and large industrial customers. In principle the משווק is a shipper in …
Term used for the possible routes or movement of pressurized gas along a preferential path. The movement of hydrocarbons from their source into reservoir rocks. Primary migration is the movement of newly generated hydrocarbons out of their source rock. The further movement of the hydrocarbons into reservoir rock in a hydrocarbon trap or other area …
General terms and conditions entered into between a natural gas supplier and a consumer. A GSA or a GSPA can be a supply contract or a depletion contract. It can be short, medium or long term. Some of the main clauses in a GSA agreement include: identity of buyer, identity of seller, Securities provided by …
GTL is a generic term for a process that converts hydrocarbon gasses into liquid synthetic fuels that can then be processed into fuels or other types of hydrocarbon products such as gasoil, benzene, naphtha, kerosene (from which one can produce jet fuel), wax and other liquid fuel products. The products obtained in the process depend …
Derived annually by dividing gross natural gas withdrawals from gas wells by the number of producing gas wells on December 31 and then dividing the quotient by the number of days in the year.
Drilling fluid whose bulk, unpressurized density is reduced as a small volume of gas displaces an equivalent volume of liquid. A mud that has gas (air or natural gas) bubbles in it
Such as to drive the hydrocarbons to the surface. A reservoir is completely or partially isolated from the pressure regime in the surrounding rock. As oil is produced the gas cap above it expands. As it expands it loses energy. The temperature and pressure in the reservoir drop until eventually there is not enough energy …
Gasification is a thermo-chemical process that breaks down coal – or virtually any carbon-based feedstock – into its basic chemical constituents. In a modern gasifier, coal is typically exposed to steam and carefully controlled amounts of air or oxygen under high temperatures and pressures. Under these conditions, molecules in coal break apart, initiating chemical reactions that typically …
Gasoline which is obtained directly from crude oil by fractional distillation. Straight-run gasoline generally must be upgraded to meet current motor fuel specifications. Its important characteristics include its octane number (Ron, Mon), oxygenated/non-oxygenated, vapor pressure (RVP) – summer and winter, its sulfur content, aromates, olefines, etc.
Gasunie is a Dutch gas infrastructure company that owns one of the largest high pressure gas pipeline grids in Europe, consisting of 12,000 kilometers of pipeline, dozens of installations and approximately 1,100 gas receiving stations. In 2005, gas throughput totaled more than 95 billion cubic meters.
