1. a sandstone that yields oil. 2. (by extension) any reservoir that yields oil, whether or not it is sandstone.
Industry:Oil & gas
the hole made by the drilling bit, which can be open, cased, or both. Also called borehole, hole, or wellbore.
Industry:Oil & gas
an internal-combustion engine used to power a drilling rig. These engines are used on a rotary rig and are usually fueled by diesel fuel, although liquefied petroleum gas, natural gas, and, very rarely, gasoline can also be used.
Industry:Oil & gas
a gland arrangement that mechanically or hydraulically seals by pressure. It is used to prevent leakage and waste of gas, oil, or water around a wireline (as when swabbing a well).
Industry:Oil & gas
a borehole; the hole drilled by the bit. A wellbore may have casing in it or it may be open (uncased); or part of it may be cased, and part of it may be open. Also called a borehole or hole.
Industry:Oil & gas
an engineer who specializes in the technical aspects of drilling.
Industry:Oil & gas
pumping oil, or a mixture of oil and chemicals, to a specific depth in the well to lubricate stuck drill collars.
Industry:Oil & gas
an acidizing treatment in which the acid is placed in the wellbore and allowed to react by merely soaking. It is a relatively slow process, because very little of the acid actually comes in contact with the formation. Also called wellbore cleanup. Compare acid fracture.
Industry:Oil & gas
circulating fluid, one function of which is to lift cuttings out of the wellbore and to the surface. It also serves to cool the bit and to counteract downhole formation pressure.
Industry:Oil & gas
the final string of casing set in a well after the productive capacity of the formation has been determined to be sufficient. Also called the long string or production casing.
