Wellsite Core Handling

Contact

Weatherford Laboratories employs several options for industry-leading methods in core stabilization. Whether it is a tight shale or an unconsolidated sand, we have the answer to your needs. 

We will work with you to understand your analytical goals and apply those needs to your reservoir, whether it is a vuggy carbonate or an unconsolidated sand. Working with these variables, we will ensure your core is stabilized to yield pristine lab results.

RocKlaw

RocKlaw was designed with one purpose in mind: handling your investment safely. The RocKlaw is a pneumatic lifting arm. It is intrinsically safe, portable, and fully functional. Musculoskeletal injuries are one of the most prevalent cause of lost time incidents. Weatherford Labs developed this product to ensure that when core sections are moved, risk to personnel, and by extension the core, is eliminated.


Stabilization Techniques:

Teflon Shims 

This method of stabilization ensures the core is locked into the tube during transport to the lab. No chemicals are involved, and shims allow the core to be easily extruded from the inner tube for a full suite of analysis. 

Epoxy 

Stabilizing the core with epoxy is the most common approach for securing the core to the inner tube, primarily for deepwater projects. We offer a full-length stabilization service in addition to  the traditional "cut and pour" method.

Foam 

Foam stabilization utilizes a two-part reactive foam chemical that is injected into the annulus of the core barrel. This protects the core from both shocks and vibrations during transport. Compared to epoxy, this technique yields the option of allowing the core to be removed from the inner tube, lending to a more comprehensive suite of analysis.

Dry ice

Freezing core samples is a practice used if the core is highly unconsolidated or has inadequate annular space to accommodate a chemical or mechanical stabilization technique. In instances like this, dry ice is utilized to freeze the core, using the in situ fluids to maintain the structural integrity of the core. This method can be done before of after the core is segmented.

Proper stabilization of your core is critical to achieving accurate analytical results once the core reaches the lab, and is a key to protecting your investment in core sampling.
