PRESSURE-WATER HOLD UP TOOL USED TO MEASURE BOTH WELLBORE PRESSURE AND A WATER HOLD UP. THE TOOL INCORPORATES A COMBINED, COMPACT DUAL SENSOR. THE PRESSURE SENSOR IS FITTED WITH A HIGH PRECISION QUARTZ GAUGE AND AVAILABLE IN DIFFERENT PRESSURE RATINGS ENSURING IT IS ACCURATE FOR LONG TERM PRESSURE BUILD UP SURVEYSAND FLUID LEVEL IDENTIFICATION. THE CAPACITANCE WATER HOLD UP SENSOR IS IT CYLINDRICAL CAPACITOR, THE PLATES OF WHICH ARE FORMED BY A CENTRAL AXIAL ELECTRODE AND THE SLOTTED HOUSING OF THE MAIN TOOL BODY. THESE ARE INSULATED FROM EACH OTHER BY AN INSULATING SLEEVE. THE CAPACITANCE OF THE SENSOR VARIES DEPENDING ON THE DIELECTRIC CONSTANT OF THE FLUID BETWEEN TWO PLATES. USED BOTH AS A CORE PRODUCTION LOGGING TOOL AND SIMPLE PRESSURE SURVEYS. LENGTH: 721 MM DIAMETER: 823MM WEIGHT: 6.2KG VOLTAGE: 12 V DC CURRENT: 23MA
