Reserve Pit	Pit used to collect spent drilling fluids, cutting and wash water during drilling operations.

Reserves	Oil or gas contained in underground rock formations called reservoirs. Proved reserves are the estimated quantities that geologic and engineering data demonstrate can be produced with reasonable certainty from known reservoirs under existing economic and operating conditions. Recoverable reserves are those that can be produced using all known primary and enhanced recovery methods
