US Patent:

44135114, Nov 8, 1983

Filed:

Mar 12, 1982

Appl. No.:

6/357516

Inventors:

John K. Godbey - Dallas TX

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

E21B 4908

US Classification:

73155

Abstract:

This invention discloses a method and system for continuously measuring the amount of solid cuttings picked up by a drilling mud being circulated in a well being drilled into subterranean formations and the amount of drilling mud carried over with the cuttings when the cuttings are separated from the drilling mud by a shale shaker. The cuttings and carryover mud discharged from the shale shaker are introduced into a vessel wherein the weight and volume of the solid cuttings and carryover mud are continuously measured and the volume fraction of solid cuttings. phi. sub. c is determined in accordance with the following equation: ##EQU1## wherein W is the weight of a fixed volume of solid cuttings and carryover mud discharged from the shale shaker, V is the volume of solid cuttings and carryover mud discharged from the shale shaker, P. sub. m is the density of the drilling mud, and P. sub. c is the density of the solid cuttings.

Appl. No.:

5/822506

Inventors:

Billy G. Ballard - Garland TX

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

F04B 4900

US Classification:

417 36

Abstract:

A source of acoustic pressure pulses is coupled to the surface casing of a well so that they are transmitted down the well and reflected by the gas-liquid interface. A transducer is also coupled to the well to produce an electrical signal in response to direct and reflected acoustic pulses occurring in the well. Gating circuitry responds to the transducer for starting and stopping the counting of clock pulses by a digital counter. The digital count controls a pump so that the liquid level in the well is precisely controlled between desired levels.

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

G01S 966

US Classification:

73155

Abstract:

Apparatus for determining the location of the liquid level in a well or borehole. A source of acoustic pressure pulses is coupled to the surface casing so that they are transmitted down the well and reflected by the gas-liquid interface. A transducer is also coupled to the well to produce an electrical signal in response to direct and reflected acoustic pulses occurring in the well. Gating circuitry responds to the transducer for starting and stopping the counting of clock pulses by a digital counter. A digital readout device is used to indicate the depth to the liquid level in the well. The acoustic pulse source is automatically actuated at predetermined times, and the depth to the liquid level and the time are automatically recorded. This produces a record of time and liquid depth which can extend over a period of several days.
