Problems solved by technology

A poor estimation leading to the pumping of a lesser volume than accurately needed or the pumping of a greater volume than accurately needed tends to be costly and therefore undesirable.
An insufficient volume of cement may, for example, cause portions of casings or liners to be inadequately cemented while excess volumes of cement may cause cementing of downhole tools that were never intended to be cemented.
Actions to correct the effects of over and under cementing inevitably cause delay and as noted are generally costly.

Embodiment Construction

[0008]A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0009]Referring to FIG. 1, an embodiment of a downhole well completion operation monitoring system 10 disclosed herein is illustrated. The monitoring system 10, among other things includes, a wired pipe 14, a monitoring device 18, shown herein as a computer, and one or more transducer(s) 22, for monitoring a downhole operation associated with completion of the well or initiating actuation of a completion operation. The wired pipe 14 has a wire 26 capable of carrying electrical signals and power therethrough. The wire 26, at a minimum, electrically connects the monitoring device 18 with the transducer(s) 22 to permit at least one-way, and often two-way, electrical communication between the monitoring device 18 and the transducer(s) 22. Such electrical communication allows the monitoring device 18 ...

Abstract

A method of monitoring axial or radial displacement of a member during a downhole completion operation includes, sensing axial or radial displacement of the member during the downhole completion operation with the at least one transducer, and communicating the sensing of the axial or the radial displacement to surface via the wired pipe.

Description

BACKGROUND[0001]Operators in the hydrocarbon recovery industry typically rely on estimations to determine when a particular well completion operation is finished. One example of a well completion operation where estimation is employed is a cementing operation. An operator may estimate a volume of cement needed based upon his best information of the length and annular area that is to be cemented. A poor estimation leading to the pumping of a lesser volume than accurately needed or the pumping of a greater volume than accurately needed tends to be costly and therefore undesirable. An insufficient volume of cement may, for example, cause portions of casings or liners to be inadequately cemented while excess volumes of cement may cause cementing of downhole tools that were never intended to be cemented. Actions to correct the effects of over and under cementing inevitably cause delay and as noted are generally costly. Operators will likely look positively on systems and methods that rem...
