free grains of sand pulled loose by flow, brittle failure or formation disaggregation and produced with the hydrocarbon production.

n: a metal drum on a drilling rig or a workover unit around which the sand line is wound. On a drilling rig, it may be attached to the drawworks catshaft and may be used for coring or other wire line operations. When used on a drilling rig, it is some- times called a coring reel.

n: The reel be used to draw the bailer in the work of bailing.

n: see wire-wrapped screen.

a downhole screen designed to stop sand production before the flow enters the pump or tubing.

n: a steel tank placed under the shale shaker into which mud falls after passing through the shale shaker. The shaker re- moves mainly cuttings from the mud so solids such as sand and other fine particles fall with the mud into the sand trap. Many of the solids fall out of the mud in the sand trap: those that do not settle out are removed with other specialized solids control mud treatment equipment such as desanders and desilters.

n: A small pit, typically located immediately after the shaker screens, which is used as a settling pit to separate coarser solids that accidentally bypass the shakers. Mud enters the pit at one side and exits via an overflow at the other. Sand traps are dum

a surface vessel in the production line with the specific task or capturing sand before the production goes through a point where the sand may damage equipment.

a map that uses contours to show the ratio of sand to shale in a formation. Useful for determining clean sand trends and permeability channels.

adj: 1. of a well, under restricted production because of sand accumulation in the wellbore. 2. impeded or hindered, especially because of sand accumulation.
