Open Hole Wireline

Open Hole Wireline tools are used to determine commercial viability of a well

Open Hole formation evaluation helps define the properties of a well after the initial drilling process has been completed. Collecting formation information is the corner stone of GEs Open Hole Ultrawire™ Formation Logging Tools (U-FLT), and is vital in determining the feasibility and commercial viability of the well. GE's Open Hole Wireline tools provide crucial information about a well that cannot be obtained through other means.

The Sondex Wireline Open Hole Formation Evaluation tools provide definitive data concerning formation porosity, resistivity and gas determination. They also enable enhanced and accurate Sw and lithology calculations. Utilizing the basic U-FLT allows operators to fully comprehend the parameters of their well and confidently plan the next stage in its development.

Formation Evaluation tools are used to obtain formation and reservoir properties using an array of tools designed to measure varying aspects of the formation adjacent to the borehole wall. This information is then used by oil companies to:
  • Determine the presence of hydrocarbons
  • Determine the quality of reservoirs
  • Determine the porosity and permeability of reservoirs
  • Determine water saturation of reservoirs
  • Determine mechanical properties of the formation

The Open Hole Formation Evaluation Tools include:
