n: a method of killing a well that has kicked, in which the choke size is adjusted to maintain a constant casing pressure. This method does not work unless the kick is all or nearly all salt water. If the kick is gas, this method pressure, because gas expands as it rises in the annulus. In any case, it is not a recommended well-control procedure.

n: a person who contracts with an oil company to supervise the operations at a drilling site or well site and to coordinate the hiring of logging, testing, service, and workover companies

n: a type of metamorphism that occurs when an intruded body of molten igneous rock changes the rocks immediately around it, primarily ny heating and by chemical alteration.

n: Control three aspects of drilling fluid: 1) density controlling;2) viscosity and shearing force controlling;3) filter loss controlling.

n: an electric log in which current flow in the logging tool was dispersed through the mud in the wellbore prior to entering the formation. As a result, formation resistivity measurements were often inaccurate. These logs are no longer used.

oil, gas, coal. The source of the energy may also have bearing on the definition. Unconventional hydrocarbon energy sources include shale oil (both mature and immature),shale gas, and tight gas (ultra low permeability, usually less than 0.001 millidarcy)

n: a device for changing alternating current to direct current or vice versa;usually, if the device changes AC to DC, it is called a rectifier.

n: a substance formed when two or more substances polymerise at the same time to yield a product which is not a mixture of separate polymers but a complex having properties different from either polymer alone. See polymer. Examples are polyvinyl acetatemaleic anhydride copolymer (clay extender and selective and selective flocculant),acrylamide-carboxylic and copolymer (total flocculant).

n: The product manufactured by the copolyreaction of two or more element.

a mixture of two or more polymers which polymerize at the same time and with some degree to linking to yield results unlike either polymer used alone.

n: a tropical cyclone in Mexico. core n: 1. a cylindrical sample taken from a formation for geological analysis. 2. the metallic, partly solid, and partly molten interior of the earth, about 4,400 miles (7,084 kilometres) in diameter. 3. the central, axial member of a wire rope around which the strands are laid. v: to obtain a solid, cylindrical formation sample for analysis. See radiator core.
