Abstract: Liquid flow detection is described herein. One method for liquid flow detection includes heating a zone of liquid in a closed system, measuring changes in liquid temperature of the zone, and detecting a liquid flow pattern based on the measured changes in liquid temperature of the zone.

Abstract: A frac plug system for use at the end of well drill string in a fractured underground formation, including an elongated mandrel body, a nose cone, a mandrel head, and a sealing assembly; at least one sensor positioned on the nose cone, the sensor being optionally a temperature sensor, pressure sensor, pH sensor, or fluid composition sensor; a battery operated microcontroller located in the mandrel body, the microcontroller constructed and arranged to periodically read the data output of the sensor and store the data from the sensor; a transmitter constructed and arranged to transmit the stored data from the set of sensors to a receiver on a pup joint when the receiver is in receiving range of said transmitter, the receiver constructed and arranged to write the transmitted stored data to an electronic memory; and whereby the data may be retrieved from the electronic memory.

Abstract: A computer operations center that has a number of computing systems, where each computing system issues system messages regarding such computing system. Each issued system message from each computing system is stored in a message logging database. The system messages stored in the message logging database are monitored for predetermined patterns, and upon detecting a particular pattern in the system messages, a predetermined action corresponding to the detected pattern is taken. The detected pattern anticipates an occurrence of an unwanted system event, and the corresponding action is intended to prevent or at least minimize the unwanted system event.

Abstract: A frac plug system for use at the end of well drill string in a fractured underground formation, includes an elongated mandrel body, wherein the front portion of said elongated mandrel body includes a nose cone, the rear of said elongated mandrel body includes a mandrel head and the mid-portion of said elongated mandrel body includes a sealing assembly; a set of sensors positioned on said nose cone, said set of sensors being selected from a group including: temperature sensors, pressure sensors, pH sensors and fluid composition sensors; a battery operated microcontroller located within said mandrel body, said battery operated microcontroller constructed and arranged to periodically read the data output of said set of sensors and store said data from said set of sensors; a transmitter electrically connected to said battery operated microcontroller, said transmitter constructed and arranged to transmit said stored data from said set of sensors to a receiver when said receiver is in receiving range of said trans

Abstract: An interactive electronic method for selecting and ordering subsections of a form has a user aspect that includes accessing a database housing a record containing at least one form that includes a plurality of subsections and indicia relating to the form and the subsections. At least a portion of the indicia are viewed, from which at least one of the subsections are chosen, if desired, by selecting the related indicia. When the selections are complete, the chosen subsection is ordered, and the user receives an electronic file containing an automatically assembled, unitary document incorporating the ordered subsection. The provider's aspect includes electronically offering and delivering the form subsections to the user by providing an electronic interface between a user and the database, permitting the user to choose and order a subsection, assembling the ordered subsection into a unitary document, and delivering the unitary document electronically to the user.
