n: a series of open-chained hydrocarbons. The two major classes are d1e series with saturated bonds and the series with unsaturated bonds.

n: rock layers folded in the shape of an arch. Anticlines sometimes trap oil and gas. Compare syncline.

n: A configuration of folded and stratified rock layers in the shape of an arch. Often associated with a trap.

a convex-upward formation of rock layers (a fold with the strata sloping down on the sides from a common crest. In association with a sealing rock, an anticline may form a trap for hydrocarbons. Anticlines may be faulted or unfaulted. The majority of the

n: a colloidal clay, composed primarily of montmorillonite, that swells when wet. Because of its gel-forming properties, bentonite is a major component of waterbase drilling muds. See gel, mud.

a reference to colloidal clay (generally montmorillinite or smectite),generates plastic viscosity due to clay behavior, size and electrostatic layer. A slurry of which used for P&A Purposes will weigh no less than 9 ppg.

v: to empty or depressure a vessel. Also called depressure.

to release gas pressure. In a reservoir, blow down is often after the oil recovery phase has been complete and the majority of the gas from the gas cap needs to be recovered.

n: a major area of oil production in the British sector of the North Sea.

a North Sea field with a light crude oil used for cost comparisons.

n: (CAODC) a trade association that represents virtually 100% of the rotary drilling contractors and the majority of well service rig operators in western Canada. The relations, and other matters of interest to members. Address: 540 5th Avenue SW, Suite 800;Calgary, Alberta, Canada T2P OM2;(403) 264-4311;fax (403) 263-3796.

a geologic epoch from today to 65 million years ago. Few major hydrocarbon bearing strata unless fluids have migrated to a trap from older source rocks.

n: The process that different material points attract each other and become major object.

n: a circular paper or lightweight plastic chart on which circular graduations are printed and on which a pen or stylus draws a recording indicating the quantities being measured. Conventional charts have a uniform scale in that minor graduations are spaced an equal distance between major graduations.

n: the process of breaking down large chemical compounds into smaller compounds under the influence of heat or catalysts. In petroleum refining, the two major types of cracking are thermal cracking and
