Abstract: A method of servicing a wellbore is provided. The method comprises establishing a communication link between a wellsite and a central control site, wherein the communication link carries sensor, audio, and video data to the central control site and carries command parameters to the wellsite to command wellbore servicing equipment on the wellsite. The data transmitted by the wellsite is analyzed at the central control site, stored in a data store at the central control site, and the results of analysis displayed on a display at the central control site.

Abstract: A method of servicing a wellbore, comprising establishing a pumping profile having a performance plan, determining a remaining life estimate for a first wellbore servicing device, wherein the first wellbore servicing device is suitable for impacting conformance to the performance plan, and selecting a second wellbore servicing device in response to the remaining life value for the first wellbore servicing device, wherein the second wellbore servicing device is suitable for impacting conformance to the performance plan. A wellbore servicing system, comprising a first device suitable for impacting conformance to a performance plan, a first sensor configured to monitor an operational characteristic of the first device, and a controller in communication with the first sensor, the controller being configured to calculate at least one of a remaining life estimate of the first device and a probability of survival estimate of the first device.

Abstract: A method of unsticking a material delivery apparatus comprises automatically generating and applying to the material delivery apparatus a cyclical drive signal that causes at least two levels of torque to be applied to the material delivery apparatus.

Abstract: A self-contained downhole apparatus for being lowered into an oil or gas well to internally record samples of at least one environmental condition comprises three body sections linearly and releasably interconnected. One of the body sections is a selected one of a plurality of transducer housing sections. The selected transducer housing section is mechanically and electrically connected to a second body section containing microcomputer-operated signal processing circuitry. The third body section contains a power supply.

Abstract: Fluid level in a container is determined using a single pressure transducer connected to a portable body. The body contains a computer having a memory in which fluid level-to-fluid volume conversion data are stored for different shapes of containers so that fluid volume can be readily obtained for the shape of the respective container once fluid level is determined. These features allow a single monitoring apparatus to be used for monitoring different types of containers. The apparatus preferably includes a radio so that multiple apparatus can communicate in a system with a central remote operator interface device. Fluid level is determined by dividing a pressure reading from the bottom of the fluid by a fluid density determined from two prior pressure reading taken across a known distance (density equals the difference between the two readings divided by the distance).

Abstract: A system and method for mixing cement slurries at an oil or gas well site and for pumping such slurries into the well provide automatic combined and interrelated density and pumping control and selectable sequential control of predetermined mixing and pumping stages. Specific conditions automatically controlled include water rate, water pressure, slurry density, recirculating slurry pressure and downhole pump rate. Each of these conditions is the subject of a respective control loop that operates independently, but under control from a central controller. The central controller generates interrelated inlet water, inlet dry cement and outlet downhole pumping control signals responsive to operated-entered desired operating characteristics.

Abstract: A self-contained memory gauge includes either semiconductor or magnetic core memory for retaining downhole information related to sampled parameters, such as borehole temperature and pressure. A microprocessor-based computer manages the power utilization by independently and selectably energizing and de-energizing different sections of the gauge. The magnetic core memory is tested for operability, and the addressing of the magnetic core memory is adjusted in accordance with any inoperable memory locations. Samples of the monitored environmental conditions can be taken at variable rates dependent upon software monitoring of the condition, the remaining battery life and the remaining memory capacity and in response to hardware monitored pressure changes. Each sample can be taken to a selectable resolution. A watchdog circuit monitors the microprocessor to insure that it is operating within a preselected time limit.

Abstract: In an oil well instrumentation system, the downhole sensor system is controlled by a computer which is powered-on only during sampling movement. An independent circuit, continuously powered, detects significant sensor rate-of-change values whereby the computer-sampling equipment is powered-on. A self-contained memory gauge includes either semiconductor or magnetic core memory for retaining downhole information related to sampled parameters, such as borehole temperature and pressure. A microprocessor-based computer manages the power utilization by independently and selectably energizing and deenergizing different sections of the gauge. The magnetic core memory is tested for operability, and the addressing of the magnetic core memory is adjusted in accordance with any inoperable memory locations.
