Glossary
annual contract quantity (ACQ). Yearly total delivery quantity as specified in a gas sale agreement or an LNG sale and purcha agreement.
associated gas. Natural gas that occurs with crude oil rervoirs, either as free gas or dissolved in solution. It is usually produced with crude oil.
barrel of oil equivalent (boe). A unit ud to equate natural gas and other nonliquid fuels to crude oil bad on the amount of heat relead when combusted. In general, 1 boe ? 5.8 Mcf to 6.0 Mcf natural gas, depending on the heat content and composition of the gas.
ba load. The minimum amount of steady electric power generated over a given period of time, operated to rve around-the-clock demand.
bcf. An abbreviation for billion (109) cubic feet. Unit ud to measure large quantities of gas, approximately equal to 1 trillion (1012) Btu.
bcfd. An abbreviation for billion cubic feet per day. Unit ud to measure the daily volume of gas produced, stored, transported, or consumed.
bcm. An abbreviation for billion cubic meters. Unit ud to measure large quantities of gas, approximately equal to 35.3 bcf.
bcmd. An abbreviation for billion cubic meters per day. Unit ud to measure the daily volume of gas produced, stored, transported, or consumed.
British thermal unit (Btu). An energy unit equivalent to the amount of energy needed to rai the temperature of 1 pound of water 1°F from 58.5°F to 59.5°F under standard pressure of 30 in. of mercury. Commonly ud for measuring gas and other energy sales quantities.
butane (C4H10). A normally gaous LPG hydrocarbon extracted from natural gas or refinery gas streams.
cascade process. A natural gas liquefaction process that us a ries of refrigerants to obtain successively lower temperatures. This process is mainly promoted by ConocoPhillips and Bechtel.
ceiling price. The maximum contracted price that may be charged for gas, LNG, and other commodities as specified in the sales contract. Contrast with floor price, which is the lowest or minimum price that can be charged, as specified in the sales contract.无人生还2012
coal bed methane (CBM). Natural gas, primarily methane, generated during coal formation and recovered by pumping water from coal ams, allowing gas to escape through shallow wells.
combined cycle. An electric generating technology in which conventional gas combustion turbines are combined with heat recovery steam-powered generation units, increasing the overall efficiency of the generating facility. Electricity is produced from both the feed gas as well as from otherwi lost waste heat exiting gas turbines. In a conventional steam power generating facility, electricity is generated only from the feed gas.
compresd natural gas (CNG). Highly compresd natural gas stored and transported in high-pressure containers, typically greater than 3,000 psi (200 bar). Commonly ud for transport fuel.古装三级电视剧
强龙不压地头蛇condensates. Light hydrocarbon compounds that conden into liquid at surface temperatures and pressures. They are generally produced with natural gas.
conventional gas resources. General term ud to describe associated and nonassociated gas found within sandstone and limestone rervoirs.
cost-insurance-freight (CIF). LNG sales contract in which the buyer takes ownership of the LNG carg快乐王子思维导图
o at the loading port or during the ship's voyage to the receiving facility. The LNG ller is responsible for the delivery of the cargo, and the contracted sales price includes transportation and insurance costs.
cubic feet (cf). Common unit of measurement of gas volume equivalent to the amount of gas
required to fill a volume of 1 cubic foot under given temperature and pressure conditions.
劳动协议书范本daily contract quantity (DCQ). Average daily quantity of natural gas contracted by the gas ller to the gas buyer.
朋友圈个性签名delivered ex-ship (DES). LNG sales contract in which the buyer takes ownership of the LNG cargo at the receiving port. The LNG ller is responsible for the delivery of the cargo, and the contracted sales price includes transportation and insurance costs.
dry gas (lean gas). Natural gas, mainly methane, which remains after liquid hydrocarbon components have been removed, making it suitable for pipeline shipping, LNG processing, or industrial usage.
engineering, procurement, construction (EPC) contract. Contract, typically on a lump-sum basis, awa
rded to an engineering company during the project execution pha for detailed design, procurement of all the equipment, and construction of the project. The engineering company is responsible for directly contracting with subcontractors and suppliers.
ethane (C2H6). A normally gaous NGL hydrocarbon extracted from natural gas or refinery gas streams.
flaring. The process of disposing uncommercial or otherwi unwanted gas by burning. Operators often flare associated gas in regions with limited gas
markets.
floor price. The minimum contracted price that may be charged for gas, LNG, or other commodities as specified in the sales contract. Contrast with ceiling price, the maximum price that may be charged for the commodity as specified in the sales contract.
标准差是什么fractionation. The step process that parates NGL hydrocarbons into distinct components, such as ethane, propane, and butane.新生儿祝福
free-on-board (FOB). LNG sales contract in which the buyer takes ownership of LNG as it is loaded
on ships at the LNG export facility. The buyer is responsible for LNG delivery, either on its own ships or ships chartered by the buyer. The contracted sales price does not include transportation costs or insurance.
front-end engineering design (FEED) study. Project design study typically conducted by an engineering company during the project definition pha.
gas cap. Natural gas prent in upper portions of a rervoir, typically above the oil and water layers.
gas initially in place (GIIP). The total gas volume prent in a rervoir or field. Rerve estimates include the proportion of GIIP volumes that can actually be produced.
