n: a form of electric submersible pumping for artificial lift, in which the pump can be run or pulled on the power cable. This type of pump installation is made possible by power cables designed for tensile loads in excess of 100,000 pounds (45,360 kilo- grams).

n: a drilling fluid made up mainly of chemical salts, such as sodium chloride, calcium chloride, or potassium chloride. Clear brine contains little or no clay or other solid material and is virtually transparent. It is often used when drilling into a producing formation because clear brine minimises formation damage. See completion fluid formation damage.

a brine without suspended solids.

n: a combination of a demulsifier and solvent that is used during testing for the suspended S& W content of oil and during other operations.

n: a porous medium through which a fluid is passed to separate particles of suspended solids from it.

n: refer tofilteration

n: the process of filtering a fluid.

n: The process of separation of suspended solids from liquid by forcing the liquid through a porous medium while screening back the solids. Two types of fluid filtration occur in a well: dynamic filtration while circulating, and static filtration when the fl

mud with a low suspended solids quantity. It may be formulated with a brine with high density created by dissolved salt.

n: an arrangement for producing a well in which one wellbore penetrates two or more petroleum- bearing formations. In one type, multiple tubing strings are suspended side by side in the production casing string. each a different length and each packed to prevent the commingling of different reservoir fluids. Each reservoir is then produced through its own tubing string. Alternatively. a smalldiameter production casing string may be provided for each reservoir, as in multiple miniaturised or multiple tubing- less completions. See dual completion.

n: an arrangement for producing a well in which one wellbore pentrates two or more petrolum-bearing formations that lie one over the other.the tubing strings are suspended side-by-side in the production casing, each a different length and each packed off to

having multiple and often separate completions into different producing pays but in the same wellbore. The completions may be concentric or side-by-side where the pays are not to be commingled or stacked where the flow is to be commingled.

n: a heater used to warm the sample before and during centrifuging to determine suspended S & W content.

n: determination of the relative percentages of substances, e.g., the suspended solids in a drilling fluid that pass through or are retained on a sequence of screens of decreasing mesh size. Also called sieve analysis.

n: The solid phase grains in the drilling fluid pass different sizes screen for knowing the distribution of sizes .


particle size distribution of a sand sample made by running the sample through a set of screens.

n: a circular steel device that holds slips supporting a suspended string of drill pipe, casing, or tubing. A spider may be split or solid.

n: A round steel unit where has a cone shaped hole in the middle,which can suspend drill pipe,casing and oil tube .

a round device that holds the slips when supporting a string of drill pipe on a rig.
