Formation Evaluation

Comprehensive, accurate data helps get the most out of your well during every phase of wellsite operations

The more information you know about the surrounding formation, the better prepared you are for critical well decisions. The Renegade suite of formation evaluation tools provides data that helps plan drilling, completion and production operations.  

  • Determine overall formation porosity 
  • Identify shale or gas behind the casing 
  • Identify zones of interest and perforating depths 
  • Provide depth correlation between logging runs and between wells 
  • Provide information about the mineralogy of formations 

    The Renegade Difference 

    Renegade crews have years of experience to help plan and execute your next formation evaluation job. We have a full suite of nuclear, sonic, caliper and other tools for any formation. Plus, our experts can analyze the results and help plan the next steps to complete the well, maintain or increase production or plan P&A. Our crews are trained to safely store, handle and transport the nuclear sources needed in these operations.    


    RASP™ Reservoir Analysis Sonde Prospector 

    The Renegade Reservoir Analysis Sonde Prospector (RASP™) pulse neutron tool helps characterize the formation and provide information the operator needs to make timely decisions on well performance and well planning.

    Compensated Neutron Log

    A compensated neutron log is useful for identifying zones of interest and determining perforating depths, tracking gas cap movement and gas encroachment under shale layers, as a correlation between open and cased hole where a gamma ray is not indicative, and to measure overall porosity of the well. At Renegade we primarily use the compensated neutron log (CNL) to identify pay zones in a well. Once the zones of interest are identified and logged, the engineer can make an informed decision on perforation placement.

    Gamma Ray Log

    The Gamma Ray Log measures total natural radioactivity and is displayed in American Petroleum Institute (API) units. The measurement can be made in both openhole and through casing. Shales and clay are responsible for most natural radioactivity, so the gamma ray log is often a good indicator of such rock. The log is also used for correlation between wells, for depth correlation between open and cased hole, and for depth correlation between logging runs.

    SWAT Spectral Well Analysis Tool

    A successful well completion is a critical part of your well’s production plan. Renegade Tracer Technologies monitors the frac job to optimally place proppant and fluid and verify job performance. SWAT Spectral Well Analysis Technology is Renegade’s line of post-frac logging tools used to identify and define radioactive isotopes. These tools offer real-time or memory data in a 1-11/16-in. OD tool configuration. 

    • Locates radioactive tracers 
    • Identifies fractures 
    • Helps optimally place proppant and fluid 
    • Verify performance of the frac job

    Spectral Gamma Ray Tool

    Spectral Gamma Ray Tool provides information about the mineralogy of formations, specifically the source of a particular gamma ray by measuring the amplitude or energy level. Since the most frequent sources of natural radiation in the formation are thorium, uranium and potassium, the tool can measure the amount of each in shale and sand formations.  

    • Provides detailed stratigraphic correlation 
    • Identifies depositional environments 
    • Determines clay type analysis and volume 
    • Heavy mineral identification 

    The tool utilizes a large, ruggedized scintillation detector to measure the quantity of naturally occurring potassium, uranium and thorium. The total gamma spectrum is resolved into 256 channels internally and used to determine the components of naturally occurring radiation in sands and shales. This data is used to distinguish important features of the clay or sand around the wellbore formation such as clay volume, clay type, heavy minerals and is also used for fracture detection.

    The detector package is designed to maximize the energy spectra sensitivity over the entire range of energy levels and logging speeds encountered in various formations. The tool uses an automatic internal stabilization circuit to stabilize the detector and electronics for temperature drift errors over the entire operating temperature range.
