Downhole Shut In Tool technology...A down hole shut-in tool's purpose is to enable the well-bore to be shut in down hole rather than at surface. The process of shutting in a well down hole eliminates the “well bore storage effects”. Well bore storage effects are the result of long lengths of production tubing that need to be pressurized before the buildup can be recorded. The benefit of using a down hole shut in tool, is to allow for a quicker well build up and better pressure data quality. This saves operators money on down time, and gives reservoir engineers better data for their calculations.
There are two common sizes of valves, a 1.75” OD valve used for 2-3/8” and 2-7/8” tubing and a 2.5” OD valve for 3-1/2” and larger tubing.
DataCan has a unique valve design that closes instantaneously giving the production engineer the best available pressure build up data.
DataCan’s valve has the ability to re-open and close multiple times, this is necessary when reservoir engineers are performing three or four point isochronal pressure tests. DataCan’s production and injection valve designs are currently patented in the United Stated and Canada.
High Temperature Use
Our motor and controls circuit has recently operated in a production 151°C gas condensate well. This well is the highest field temperature we've seen and is a milestone for shut in tool operations. Through labratory testing, DataCan can confidently rate its drive section to 150°C. Further engineering is in progress to raise the operating temperature of the down hole shut in tool to 165°C and higher.
The DataCan instant close / multi-cycle down hole shut in tool is highly durable. Shut in tools are often mounted below locks or plugs. As such, it is neccessary that our valve and drive section are capable of withstanding the most physical of down hole conditions.
