n: a federal entity such as a department, a bureau, a corporation, a commission, or a division under the US government that is charged by Congress to administer, implement, and enforce US law. agglomerate n: the groups of larger individual particles usually originating in sieving or drying operations.

n: a roller cone bit that is specially designed for air or gas drilling. It is very similar to a regular bit, but features screens over the bearings to protect them from clogging with cuttings and thicker hardfacing on the shirttail to protect them from abrasive, high-velocity air or gas drilling fluid.

n: Used compressive air which replaces flushing fluid as circulation media to cool the bit and carry over cuttings.

n: a body of air that remains for an extended period of time over a large land or sea area with uniform heating and cooling properties. The air mass will acquire characteristics (such as temperature and moisture content) of the underlying region.

n: an area over which an air mass rests and develops temperature and moisture characteristics typical of that location.

basic or pH over 7.

n: a method of improved recovery in which alkaline chemicals such as sodium hydroxide are injected during a water flood or combined with polymer flooding. The chemicals react with the natural acid present in certain crude oils to form surfactants within the reservoir. The surfactants enable the water to move additional quantities of oil from the depleted reservoir. Compare chemical flooding, polymer flooding, water flooding.

n: Affiliated to a kind of parbighite that can combine with alkylene, usually used as diluent and calcium remover which can resist certain temperature.

n: the amount of oil or gas that can be produced legally from a well. In a state using proration, this figure is established monthly by its conservation agency. See proration.

the production limit set on a specific well by a government regulatory body. Rarely seen.

n: a large, sloping sedimentary deposit at the mouth of a canyon, laid down by intermittently flowing water, especially in arid climates, and composed of gravel and sand. The deposit tends to be coarse and unworked, with angular, poorly sorted grains in thin, overlapping sheets. A line of fans may eventually coalesce into an apron that grows broader and higher as the slopes above are eroded away.

land counterpart of a river delta. Characteristic of sediments that have been transported by a fast moving stream then dropped out of the flow as the stream velocity drops as it spreads out. Typical of zones of heavy water runoff such as found at the base
