n pi: 1. the well cuttings obtained at designated footage intervals during drilling. From an examination of these cuttings, the geologist determines the type of rock and formations being drilled and estimates oil and gas content. 2. small quantities of well fluids obtained for analysis.

n: cuttings obtained for geological information from the drilling fluid as it emerges from the hole. They are washed, dried and labelled as to the depth. Also, a portion of well fluid recovered on a DST.

a sand restraining device that is a mesh or wire wrapped screen wound over a base pipe with holes.

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: 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.

laying a sand plug over the lower perfs to cover and protect them form another operation.

prediction of where in the wellbore that scale minerals are oversaturated in solution and could form scale. Not necessarily where scale will form.

n: the NEPA process of identifying the scope and significance of important issues associated with a proposed federal action and identifying alternatives to that action through coordination and consultation with government (federal, state, and local),the public, and any interested individuals or organizations.

a graph or the production performance of wells against the cost of operations to achieve that production – particularly useful for comparing the effectiveness of workovers.

a reusable, reloadable perforating gun with port plugs over the perforating charges.

n: 1. a vessel through which fluids are passed to remove dirt, other foreign matter, or an undesired component of the fluid. 2. a vessel with or without internal devices used to separate en- trained liquids or solids from gas. It may be used to protect downstream rotating equipment or to recover valuable liquids from a gas or vapor originating upstream. 3. a unit that removes carbon dioxide from the divers breathing medium by chemical absorption.

a reactor that removes various components from produced gas.
