Abstract: Methods and apparatus are provided for continuously powering tools downhole for extended periods of time, such as for the life of the producing well. Batteries may power the downhole tools, but traditionally, the batteries may last up to 2 years, and in some cases, up to 5 years may be reached with an optimized data sampling rate and power management scheme. After that time, operations may be halted temporarily for replacing the batteries. According to embodiments of the present invention, in contrast, rechargeable batteries 204 may be utilized downhole to provide power to operate the tools, and rather than halting operations and retrieving the rechargeable batteries 204 to the surface for recharging, reserve batteries 208/210 may be used for recharging the rechargeable batteries 204. In many cases, these well tools may be designed to operate for a long period of time (e.g., around 10-20 years), depending on the life of the producing well.

Abstract: A method of conducting a gravel pack operation comprising lowering a fluid control assembly into a wellbore and supplying a fluid mixture comprising gravel into an annulus between the fluid control assembly and the wellbore to form a gravel pack. A washout assembly surrounds a pre-determined length of the fluid control assembly to remove gravel pack from around the predetermined length. A tattle-tale sub provides an indication of the location of the washout assembly relative to the fluid control assembly. The placement of a cement or inflatable packer is controlled relative to the pre-determined length of the fluid control assembly.

Abstract: Methods and systems are provided for performing acoustic sensing by utilizing distributed acoustic sensing (DAS) along a length of a conduit, such that the sensing is performed with the functional equivalent of tens, hundreds, or thousands of sensors. Utilizing DAS in this manner may cut down the time in performing acoustic sensing, which, therefore, may make acoustic sensing more practical and cost effective and may enable applications that were previously cost prohibitive with discrete acoustic sensors.
