Wellsite Services - Wellsite Core Stabilization Services


Core stabilization is required to protect and stabilize the core within the liner in which they recovered. Without stabilization core can be damaged during routine handling and transportation from the field to the laboratory facilities. We offer a full range of services to stabilize conventional cores within the core barrel liner that are collected in. The type of stabilization method is designed to match the formation type and the core conditions.


Wellsite Services - Wellsite Core Stabilization Services includes:

CoreFreeze

The process involves full barrel freezing of core from unconsolidated or friable formations when received at the well site. The cores internal temperature is monitored to insure a hard freeze occurs and then the liners are segmented into manageable length for safe handling and transportation. The core is kept frozen through the transportation and sample preparation process.


CoreSta™

CoreSta™ is a unique superior preservation technique for friable and unconsolidated formations. This is patented process is used as an alternative to Core Freezing. It is often used on friable or unconsolidated formations where freezing is impractical. The process involves low pressure injection of epoxy into the annular space between the core and the liner to stabilize the core before segmenting occurs. This insures that the core is stabilized in the liner before segmenting and handling to minimize the chance of core damage.


Tilt & Pour

This process is an older version of epoxy stabilization that involves segmenting friable or unconsolidated core into 3 foot sections. Epoxy is "poured" into the annular space to immobilize the core within the sectioned liner. It may be used when CoreSta is not available and or injection pressure is of concern.


Mechanical Shim

This process is designed to stabilize consolidated formations in the liner to movement and breakage during transportation. Shims are inserted in the annular space between the core and the liner. The shims are designed to wedge between the core and are non-reactive with the formation or the fluids present.
