n: a liner that has had holes shot in it by a perforating gun. See liner.

n: the liner in which the hole have been made before it assembled and run in the wellbore, it provides the channel for the oil flow.

a liner with holes drilled for fluid entry. Not usually for sand control but may be useful for increasing hole stability or access.

n: sections of pipe (such as casing, liner, and tail pipe) in which holes or slots have been cut before it is set.

n: A wellbore tubular in which slots or holes have been made before the string is assembled and run into the wellbore. Perforated tubes typically are used in small-diameter wellbores or in sidetracks within the reservoir where there is no need for the liner
لوله ی مشبک

n: A specially prepared fluid placed in the wellbore over the interval to be perforated. The ideal fluid is clean and solids-free (filtered),and will not react to cause damaging by-products on contact with the reservoir formation. Perforating in a dirty flu

n: lowed the level of liquidin the wellbore, which made the pressure of hydrostatic column below the pressure of shoting layer, under that condition, shoting is perforated that can lower the degree of pollution.

n: a hole made in the casing, cement, and formation through which formation fluids enter a wellbore. Usually several perforations are made at a time.

n: the hole that the bullete passes through the casing and cement rock , then enters into layer.

a hole made through the casing and cement and into the formation. It has a characteristic entrance hole and penetration. It is the flow path from the formation to the wellbore in a cased and cemented completion.
مشبک کاری

n: a well completion in which production, workover, and recompletion operations can be performed without removing the wellhead.

n: lowering the bottom of oil tube to the top of production layer, fixed completely the assly of well mouth and the oil tube fastened, all the working in wellbore must use string through oil tube performed.

a petal basket that reroutes all the fluid over the diameter of the wellbore into a single flow stream near the middle so an accurate measurement with a flowmeter can be made.

n: (P.I.T.S) (Canada) an industry-controlled and industry-operated training organisation maintained specifically to assist Canadian companies with their training. Address: Bay 13,2115 27thAvenueNE;Calgary, Alberta T2E 7E4, Canada;(403) 250-9606.

n: a device used to determine the angle and direction by which a wellbore deviates from the vertical. After the instrument is run into the hole, it takes a photograph that is then brought to the surface, developed, and analysed. Photographic survey instruments can be single-shot or multishot and magnetic or gyroscopic.

n: a gelled viscous fluid placed at a specific depth in the well. usually to overcome or minimise a problem at that depth. For example. a special bentonite pill may be spotted (placed) at or near a formation to which drilling fluid is being lost. The pill may seal the formation and reduce or stop the lost circulation problem.

n: a relatively small volumn of specially prepared fluid placed or circulated in the wellbore. Fluid pills are commonly preparedfora variety of special functions, such as a sweep pill prepared at high viscosity to circulate around the wellbore lost-circulati

a volume of gelled fluid mixed for a specific purpose. A fluid loss pill for example.
