Net oil meter

Claim 1

A METER SYSTEM WITH WHICH THE NET OIL OF WELL PRODUCTION HAVING HIGH WATER-OIL RATIO IS MANIFESTED, INCLUDING A CONDUIT THROUGH WHICH THE PRODUCTION IS PASSED; A CONSTANT DISPLACEMENT PUMP IN THE CONDUIT AND MOVING THE PRODUCTION THROUGH THE CONDUIT AT A CONSTANT RATE; A POSITIVE DISPLACEMENT METER IN THE CONDUIT RECORDING THE TOTAL VOLUME OF LIQUIDS OF THE PRODUCTION; A CAPACITANCE UNIT MOUNTED IN THE CONDUIT TO RESPOND TO THE DIELECTRIC CONSTANT OF THE LIQUIDS OF THE PRODUCTION AS A PRIMARY ELEMENT; AN ELECTRO-MECHANICAL SYSTEM RESPONSIVE TO THE PRIMARY ELEMENT, AND INCLUDING, (A) A CRYSTAL-CONTROLLED VACUUM-TUBE OSCILLATOR CIRCUIT HAVING A PLATE CIRCUIT TUNED AT A PREDETERMINED MINIMUM LOAD RESONANCE OF THE CRYSTAL, (B) AN INPUT CIRCUIT INCLUDING THE PRIMARY ELEMENT CAPACITANCE UNIT, (C) A COUPLING TRANSFORMER LINKING THE PLATE CIRCUIT AND INPUT CIRCUIT TOGETHER AND TUNED TO PERMIT MAXIMUM CURRENT TO PASS IN THE PLATE CIRCUIT AT A PREDETERMINED HIGH VALUE OF DIELECTRIC CONSTANT OF THE LIQUIDS THROUGH THE PRIMARY ELEMENT, (D) A MECHANICALLY ADJUSTABLE CAPACITANCE UNIT INCLUDED IN THE INPUT CIRCUIT WHICH IS ADJUSTED TO RETURN THE PLATE CURRENT TO A PREDETERMINED VALUE, (E) AND A MOTOR RESPONSIVE TO THE PLATE CURRENT AND MECHANICALLY LINKED TO THE ADJUSTABLE CAPACITOR TO RETURN THE PLATE CURRENT TO THE PREDETERMINED VALUE; A LINKAGE-CAM-ELECTRIC CIRCUIT SYSTEM FOR TRANSDUCING THE MOTOR POSITIONS INTO ELECTRIC PULSES WHOSE CUMULATIVE LENGTH HAVE A RATIO TO THE TOTAL TIME THE POSITIVE DISPLACEMENT METER IS ACTUATED WHICH IS EQUAL TO THE RATIO OF THE WATER TO OIL IN THE LIQUIDS TO WHICH THE CAPACITANCE UNIT PRIMARY ELEMENT RESPONDS; AND A WATER REGISTER COUPLED TO THE POSITIVE DISPLACEMENT METER BY THE TRANSDUCING CIRCUIT ELECTRIC PULSES SO AS TO CUMULATE THE TOTAL WATER PASSED THROUGH THE METER, WHEREBY THE WATER REGISTER READING MAY BE SUBTRACTED FROM THE TOTAL VOLUME REGISTER OF THE POSITIVE DISPLACEMENT METER TO ASCERTAIN THE NET OIL PASSED THROUGH THE CONDUIT DURING A PREDETERMINED PERIOD.
