n: see paraffin.

n: The method that can measure drilling fluid filtration regulated by API. Refered to the filtrated volume of drilling fluid in the condition of routine pressure of 690kpa(+ or -35kpa),filter area of 4580mm2(+ or - 60mm2) and 30min.

a large, load supporting formation that may serve to reduce the total overburden load on a pay zone. These formations may cover hundreds of square miles over a basin. A second use is as a semi-stable structure of sand grains around a perforation or other

a steep sided gulley in arid areas that carries runoff, usually at high velocities, for very short times after a rain.

n: a device that, when installed in a pipe or flow channel and actuated by automatic control equipment. enables a representative sample to be obtained of the fluid flowing therein. systematic basis, which can be tested to determine the quality of the liquid flowing in the line. An automatic sampling device consists of a probe inserted into the line, an extractor, a timer or other device that controls the sampling rate, and a small tank (sample receiver) that holds the samples.

cycling coiled tubing from a yielded position, through a transition region, and back again. Running coiled tubing from the reel into a well and back to the reel involves six bends or three cycles.

n: the threaded portion of the top of the bit that is screwed into the drill collar. Also called the pin.

n: Refers to the drilling fluid gun whose nozzle is installed in the bottom of drilling fluid tin.

v: to move with a slight, irregular rhythm. Breathing occurs in tanks of vessels when vapours are expelled and air is taken in. For example, a tank of crude oil expands because of the rise in temperature during the day and contracts as it cools at night, expelling vapours as it expands and taking in air as it contracts. Tubing breathes when it moves up and down in sequence with a sucker rod pump.

secure the well or close in.
