Steel pipe placed in an oil or gas well to prevent the wall of the hole from caving in, to prevent movement of fluids from one formation to another and to aid in well control. The large diameter pipe is lowered into an openhole and cemented in place. The well designer must design casing to withstand a variety of forces, such as collapse, burst, and tensile failure, as well as chemically aggressive brines.
The cost of storing natural gas for a period of time
State owned China national offshore oil corporation. The China National Offshore Oil Corporation (CNOOC), founded in 1982, is one of the largest state-owned oil giants in China, as well as the largest offshore oil and gas producer authorized to cooperate with foreign partners for oil and gas exploitation in China ‘s offshore areas. CNOOC has maintained a momentum of rapid growth and developed from an upstream oil company exclusively engaged in oil and gas exploitation into an integrated corporation with a competitive core business and synergetic business portfolio along the value chain. It has established six business sectors, namely, oil and gas exploitation, technical services, chemical and fertilizer production and refining, natural gas and power generation, financial services, and logistic service and new energies development.
The top of the casing set in the well; the part of the casing that protrudes above the surface and to which the control valves and flow pipes are attached.
Centrica was formed in February 1997 following a demerger from British Gas plc. The new company comprised the gas supply, services and retail businesses of British Gas, together with the gas production business of the North and South Morecambe gas fields.

Centrica generated gas and power from its own resources and sells energy to end customers. Centrica no longer has any direct involvement in the transportation of natural gas, or the construction of distribution networks
The residue deposited on a permeable medium when a drilling fluid is forced against the medium under pressure. The cake that forms on the walls of the wellbore can cause stuck pipe and other drilling problems so the properties of the cake such as its thickness, toughness and slickness and permeability are important
Types of DHI. Brightness can often (but not exclusively) be caused by gas in the section. With stacked reservoirs you can get a series of stacked bright spots with other characteristics such as frequency decay and velocity sag
Expression that a company controls the entire gas chain is often known as “from the wellhead to the burner tip”. Burner tip is the use of natural gas in the home
