n: see spinner survey.

a technique in which the entry points and the amount of fluid entering the wellbore are identified.

n: any packer designed to make a seal between the tubing and the casing during production.

n: A device used to isolate the annulus and anchor or secure the bottom of the production tubing string. A range of production packer designs is available to suit the wellbore geometry and production characteristics of the reservoir fluids.

any packer that forms a seal between tubing and annulus during production.

n: a string of tubing used to produce the well, providing well control and energy conservation.

n: A wellbore tubular used to produce reservoir fluids. Production tubing is assembled with other completion components to make up the production string. The production tubing selected for any completion should be compatible with the wellbore geometry, reser

n: a fishing tool having two or more prongs with inward-facing barbs used to snag and retrieve broken wireline from the wellbore.

v: to raise the drill stem or tubing string in the wellbore.

n: a hydraulically operated tool that is run in above the fishing tool and anchored to the casing by slips. It exerts a strong upward pull on the fish by hydraulic power derived from fluid that is pumped down the fishing string.

n: A slickline or coiled tubing tool used to retrieve temporary devices, such as plugs and flow-control equipment, from the wellbore. Pulling tools are available in a range of sizes and profiles and must be compatible with the equipment to be retrieved. A co

v: to pump (a well) so that the fluid level drops below the standing valve of the pump and the pump stops working.

pumping all the fluid out of the wellbore to the point where free gas enters the pump.

adj: descriptive of any tool or device that can be pumped down a wellbore. Pump-down tools are not lowered into the well on wireline;instead, they are pumped down the well with the drilling fluid.

n: the flow pattern of fluids flowing into a wellbore from the surrounding drainage area.

n: In this method,the wellbore axis between two adjacent test points is considered to a space curve and the horizontal projection of this curve is considered to a section of arc with unchanged curvature
