Paper: Liquid Level Recorder for Oil Production Measurement

The liquid level recorder saves time and labor and insures more accurate data. A general utility recorder, it is simple to operate, inexpensive, yet extremely sensitive and accurate. It is used in the oil field for the primary purpose of recording the production of oil and/or water into the test tank or stock tank. During the life of an oil well it may be called upon to do the following: detect loss of circulating mud during drilling; measure load oil and formation oil during swabbing and initial testing; record the potential test; record fluids produced on a productivity index test and; determine the producing cycle of a gas lift or pumping operation.
