CoreXL 4.5 CoreXL 4.5

4-1/2" OD Core

Natural rock characteristics such as unconsolidated, fractures, and lack of cementation create a unique challenge to the mechanics of whole core acquisition, often creating a negative impact on recovery and efficiency.

CoreXL 4.5 - 4 1/2” OD Core technology addresses these challenges by increasing column strength and reducing drilling dynamics dysfunction.

Tool Applications

  • Fissile/friable/fragile formations susceptible to induced fracturing (ex. shale)
  • Jam prone applications
  • Natural fracture analysis
  • Long or short barrel configurations
  • Offshore or land
  • Deviated or horizontal wellbores
  • Oriented coring

Features and Benefits

12.5 increase of core surface area

  • Improved column strength
  • Greater volume of rock to sample
  • Improved drilling fluid invasion exclusion from fluid saturation plugging process
  • Allows larger plugs to be cut from core
  • Better “average” representative value for analyzing fluid flow capabilities

Reduced Bit Kerf Area

  • Less formation removal
  • Decreased energy required to shear the rock
  • Increased ROP
  • Less torque generated
  • Lower vibration
