n: 1. an accumulation of sediment on the inside of a river bend, usually consisting of sand, silt, and clay. 2. a stratigraphic trap for petroleum formed by the burial and lithification of such a sedimentary deposit.

n: (PAC) a chernical cornpound used to reduce water loss in rnuds that are affected by salt contamination.

n: a device that indicates the variation in load on the polished rod as the rod string reciprocates. A continuous record of the result of forces acting along the axis of the polished rod is provided 00 a dynamometer card, from which the perfor- mance of the well-pumping equipment is analyzed.

n: a kinds of non-ion surface active agent, mainly used as emulsifier of salt water emulsion drilling fluid.

n: several alternating emfs of the same frequency and sine wave form. A polyphase generator has two or more circuits in the field windings.

n: a kinds of non-ion surface active agent, mainly used as salt resisting fluid loss agent.

n: an opening or space within a rock or mass of rocks, usually small and often filled with some fluid (water, oil, gas, or all three). Compare vug.

n: an opening within a rock;is often filled with formation fluids.

the opening within the rock. Interconnected porosity is linked together and results in permeability.

n: the difficulty degree of transfering drilling rig.

n: a mobile submersible drilling structure consisting of a barge hull that rests on bottom. steel posts that rise from the top of the barge hull. and a deck that is built on top of the posts. well above the waterline. It is used to drill wells in water no deeper than about 30 to 35 feet (9 to 10.7 metres). Most posted barge submersibles work in inland gulfs and bays. See submersible drilling rig.

n: KCL a kinds of dissoluble inorganic salt. It usually preparation for the kalium based drilling fluid.



a salt commonly used in brines to reduce or prevent clay swelling in the formation.
