A portable oilfield fluid management system and method provides display information concerning fluid status and includes a plurality of local sensing units which can be selectively attached in any order to a plurality of different storage tanks having different sizes, shapes and capacities located in different oilfields. A plurality of cable segments each of equal predetermined length are used to interconnect the attached local sensing units to each other in a serial connection and a central touch activated monitor located away from the local sensing units is interconnected to the first attached local sensing unit by means of an elongated cable. Because the local storage units which function to measure the level of fluid in the storage tanks can be attached to the storage tanks in any order, the central touch-activated monitor autoconfigures the local sensing units by assigning binary addresses to each attached local sensing unit. The first attached local sensing unit when it receives its binary address from the central touch activated monitor, stores that binary address in its random access memory and interconnects an upstream data transmission path to enable the central monitor to assign the next binary address to the next attached local sensing unit. This process is repeated for each attached and interconnected local sensing unit until all local sensing units have a binary address. The system autoconfigures the local sensing units for each different oilfield location.

Portable oilfield fluid management system and method

The oil field lease management and security system and method of the present invention for monitoring oil field equipment and for communicating with authorized operators. The system of the present invention includes a plurality of transducers connected to the equipment for sensing operational parameters of the equipment such as fluid levels in oil field storage tanks, a plurality of controllers connected to the equipment for controlling operational components of the equipment such as determining when an oil tank is filled and activating a shut-off valve to prevent further filling of the tank, a communication access panel for allowing an authorized operator to interface with the system, and a monitoring system interconnected with the transducers, the controllers, and the communication access panel for periodically monitoring each of the transducers and the communication access panel wherein the monitoring system is capable of storing transducer information corresponding to the operational parameters from the transducers such as the levels of oil in the storage tanks and operator information from the communication access panel such as the operator's password and access code.

Oil field lease management and security system and method therefor

A storage tank level monitoring apparatus and method for determining fluid levels in a storage tank. The apparatus of the present invention includes a magnet coated with rubber for holding a pivotally mounted housing to the interior of the storage tank and an ultrasonic transducer contained within the housing for generating acoustic pulses and for receiving reflections of the acoustic pulses for producing an analog signal proportional to the reflections, a string carrying a number of reference disks vertically oriented below the housing for producing a series of reflected acoustic signals from each reference disk, and a processor connected to the ultrasonic transducer for activating the transducer and for analyzing the reflected pulses for calibrating the apparatus for environmental changes in the atmosphere above the stored fluid and for determining the level of the stored fluid in the tank. The method of the present invention includes the steps of receiving reflected pulses from each reference disk only during certain window time intervals and to calibrate the system by adjusting for environmental conditions between the transducer and the fluid level.
