Used in both depletion and supply contracts of a gas sales agreement. It is the maximum daily amount that the buyer can nominate and which the seller is obliged to deliver. It is generally set at a fixed amount of the DCQ, such as 150% thereof.

A microscopic single-celled algae with a silica-rich cell wall. Diatoms can be so abundant that they can form thick layers of sediment from the organisms that died and sank to the bottom of the sea and have become an important component of deep-sea deposits since cretaceous time

Refers to low temperature and low temperature technology. There is no precise temperature for an upper boundary but -100 degrees C is often used

Many services in the oil and gas industry are quoted on a daily rate, such as rigs. The day rate usually includes the rental of the rig, the personnel on board and basic supplies, but does not include such items as mob/demob, capital goods such as casings or special services such as logging and cementing. Thus the day rate of the rig is approximately half of the total cost of drilling a well

An LNG plant is highly energy-intensive and refrigeration section is the main consumer of energy. The operational flexibility and efficiency of the refrigeration section are critical to the overall efficiency of the LNG plant. Main cryogenic heat exchanger or MCHE is the heart of the refrigeration section and is the most important heat-transfer equipment in a base-load LNG plant. It cools and liquefies natural gas to –162 C. For process optimization, we need to look from an integrated point of view and MCHE is one of the most critical equipment in LNG process.

Natural gas that is found at depths greater than the average for a particular area
