Many wells produce salt water while producing oil. The disposal of this water is a problem to an operator because of pollution. The best solution to the problem is to pump the waste back into a form [..]

 Natural gas occurring alone, not in solution or as free gas with oil or condensate.

  A well no longer in use; a dry hole that, in most states, must be properly plugged.

  A technique for increasing the flow of oil from a well. Hydrochloric acid is pumped into the well under high pressure to reopen and enlarge the pores in the oil-bearing limestone formations.

  A display of traveltime of acoustic waves depth in a well.  The term is commonly used as a synonym for a sonic log.  Some acoustic logs display velocity.

  Organic base used in refining operations to absorb acidic gases (H2S, COS, CO2) occurring in process streams. Two common amines are monoethanolamine (MEA) and diethanolamine (DEA).

  A natural gas treatment unit for removing contaminants (H2S, COS, CO2) by the use of amines. Amine units are often skid-mounted so they can be moved to the site of new gas production. Gas containing [..]

  Wells drilled in the vicinity of a discovery or wildcat well in order to evaluate the extent and the importance of the find.

  The area immediately surrounding a successful well in which the investors (in the good well) have an implied right to participate in any future wells drilled by the same operator.
