50707256, Dec 10, 1991

Filed:

Sep 12, 1989

Appl. No.:

7/405996

Inventors:

Percy T. Cox - Houston TX
Theodore W. Nussbaum - Houston TX
Charles L. Gray - Houston TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

G01N 2722

US Classification:

73 611R

Abstract:

Oil well production is often measured by using a settling tank, pump, flowmeter and a water-cut meter. Fluid from a well being tested is allowed to accumulate in the settling tank and, after a predetermined settling time, is pumped through the flowmeter and water-cut meter for gauging. The present invention is an improved water-cut meter which first determines the impedance of the free water pumped from the tank and later determines the impedance of the oil/water emulsion emerging from the tank. The ratio of the emulsion impedance to the free water impedance is proportional to percent water-cut of the fluid during the water-continuous phase. When the emulsion switches to oil-continuous phase, the system utilizes probe impedance for the water-cut determination. Using standard techniques, the water-cut and flow rate signals are then combined to calculate the total oil and water content of the settling tank fluid.

International Classification:

G01F 174
G01R 2722

US Classification:

7386104

Abstract:

The present invention is a water cut monitor which includes a settling tank in which a quantity of fluid from a producing well is accumulated. The fluid is removed as a stream of fluid after a predetermined interval from the accumulation of the fluid by the settling tank so as to allow the accumulated fluid to separate into three phases: free water, water-continuous and oil-continuous. The flow rate of the stream of fluid is measured and a corresponding flow rate signal is provided as well as a temperature signal corresponding to a sensed temperature of the stream of fluid. The water cut monitor includes a plurality of electrodes in contact with the fluid. Injection electronics connected to at least one of the electrodes provides an injection voltage and injection current to the fluid stream and also provides signals corresponding to the injection voltage and injection current. A voltage in the fluid stream is measured and a measurement signal provided. A computer determines the water cut of the petroleum stream in accordance with the temperature signal, the injection voltage and injection current signals, the electrical phase angle signal and the measured voltage signal.

Appl. No.:

7/192640

Inventors:

Charles H. Gray - Deer Park TX

International Classification:

F16K 3164

US Classification:

137 75

Abstract:

A fire control valve and more particularly a valve installed in the flow line of a flammable or other hazardous flowable material which is normally open but will be automatically closed to interrupt the flow of flammable or hazardous material to a discharge point in the event of a hazardous condition occurring. The valve is held in an open position by a fusible link which retains a spring biased pin in engagement with a spring biased valve stem to retain the valve in open position. The fusible link will melt when subjected to predetermined conditions such as a high temperature condition which occurs in the event of a fire thereby releasing the pin and valve for movement to a closed position for stopping flow of flammable material in order to control the fire or other hazardous condition.

US Classification:

Abstract:

A method and system for detecting and identifying abnormal drilling conditions. It determines the normal pump speed-pressure ratio over the range of usual working conditions. It measures the output pressure from the pump. And it measures the speed of the pump. Then it detects a change from the normal pump speed-pressure ratio which indicates abnormal conditions. Identification of the abnormal condition depends upon whether the pump speed increased above normal or the output pressure decreased below normal. If the former, the volume of drilling fluid returning is observed in order to identify one of three conditions. If the latter, the number of decreases greater than a predetermined extent are counted over a predetermined interval of time which may indicate malfunctioning pump valve or valves.
