PathFinder Analysis of Logs Software (PALS™)

Advanced Resistivity Analysis

Advanced Resistivity Analysis produces a more accurate Rt when anomalous formation effects, such as high dielectric constants and resistivity anisotropy increase uncertainty. Inversion modeling can resolve invasion and thin-bed effects while horizontal modeling can be used to evaluate the resistivity log response in highly deviated wellbores.

Advanced Resistivity Analysis Services include:

• Dielectric Independent Resistivity
• Thin Bed Response
• Anisotropy
• Shaly Sand Analysis
• Inversion Modeling
• Borehole Corrections

PathFinder Pore Pressure Service

PathFinder offers a real-time pore pressure service utilizing LWD resistivity and/or sonic measurements. Pre-well modeling and planning is accomplished with close teamwork of the PathFinder Pore Pressure Specialists and the operating company. The pore pressure model is continuously updated while drilling incorporating real-time LWD data to optimize the mud weight so drilling can continue with confi dence. Any combination of seismic, wireline, LWD, mud log, reservoir, and geologic input can be used to analyze formation pore pressure. In addition, the Drilling Formation Tester can minimize risk with real-time calibration points for the pore pressure model. Casing point selection can be improved with a better understanding of the formation pressure around the planned casing point.

Sonic Log Analysis

Applications for the Sonic Log Analysis Service include:

• Shear Slowness Porosity
  • Critical Porosity model
  • Shear Porosity
• Natural Fracture Identification
• Synthetic Seismogram
• Rock Mechanical and Wellbore Stability

Gamma Ray Enhancement

Gamma Ray Enhancement Services corrects for borehole size, mud weight and KCl mud for a more accurate gamma value.
