n: anyone of several methods by which the loose, unconsolidated grains of a producing formation are made to adhere to prevent a well from producing sand but pemlit it to produce oil and gas.

one of various methods of consolidating the grains of an unconsolidated or weakly consolidated formation. Typically resin consolidation (epoxy, furan or phenol-formaldehyde),but may also include sodium silicate, coking, and mineral or metal precipitates.

n: the insoluble abrasive solids contents of a drilling fluid rejected by a 200-mesh screen. Usually expressed as the percentage bulk volume of sand in a drilling fluid. This test is an elementary type in that the retained solids are not necessarily silica and may not be altogether abrasive. For additional information concerning the kinds of solids retained on the 200-mesh screen, more specific tests would be required. See mesh.

n: The percentage of sand that cannt through the screen of 200 eye in the drilling fluid.

n: any method by which large amounts of sand in a sandy formation are prevented from entering the wellbore. Sand in the wellbore can cause plugging and premature wear of well equipment. See gravel pack, sand consolidation, screen liner:

one of various mechanisms for controlling formation sand movement during fluid production from a weakly consolidated sandstone.

n: a device that ejects sand at a very high velocity to cut casing being salvaged from a plugged and abandoned well.

v: to plug a well inadvertently with proppants during formation fracturing. Sanding out is usually the result of a slowed fracture-fluid velocity, or screening effect, which allows the proppants to become separated from the fluid instead of being carried away from the wellbore. Also called screening out.

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.

n: a measure of heating value for natural gas that is fully saturated with water vapor under standard temperature, pressure, and gravity conditions. This is typically a laboratory condition to standardize the amount of water vapor in the gas at a convenient, albeit arbitrary, level. This standard of measure usually has little or nothing to do with the state in which the gas is actually delivered for first sales.

n pI: hydrocarbon compounds, e.g., in natural gas and natural gas liquids, in which all carbon valence bonds are filled with hydrogen atoms.

n: liquid that is at its boiling point or is in equilibrium with a vapor phase in its containing vessel.
