X2500 36M Configuration

Extended Barrel Coring

 

A unique feature to the X2500 series conventional coring system is the Surface Adjustable Long Lead capabilites incorporated into the design.

 

Utilizing conventional steel, disposable fiberglass or aluminum inner tubes the length of core cut in a single run is only limited by the lithology of the formation to be explored.

 

Extended Barrel Coring has in some cases replaced wireline coring and greatly reduces rig time when compared to conventional coring. Most commonly used is the 27 and 36 Meter configuration in sandstones and shales while retaining 100% of the core column.

 

Leads and expasnions are quickly and easily calculated by Foothills' coring engineers when making up the core barrel during the run in hole. Once the desired length has been assembled the coring engineer can quickly and easily set and adjust the lead within 1mm from surface without the need to open the core barrel or pick up to verify. 

 

The lead and lock are set through the API connection on the top of the core barrel with a few simple turns of a wrench.
