Products and Services

The core product offered at Columbine Logging is the standard one and two man mud logging.  This service is continuously being upgraded and perfected, starting with a uniform training program for newly hired loggers, then followed up by an ongoing quality assurance and quality control program which includes client feedback.  All services may be customized for client specific situations.

Columbine Logging offers both on-site and remote geosteering services.  On-site steering is performed on the rig by our trained and experienced mudloggers.  Remote geosteering is delivered from our command center in Denver, Colorado, by experienced geologists, all of whom have previously mudlogged.  Our staff of professionals have a resume of wells which include most basins from Ohio to Nevada, and North Dakota to Southern Texas.  There are also customized schedules that may be negotiated for night, weekend, and vacation fill-in.

Well-site Geosteering Services Includes:
  • Communicate and direct time critical changes to wellbore inclination
  • Plot and monitor gamma and/ or resistivity to calculate and anticipate dip
  • End of Well (EOW) geosteering report with entire well bore path, ROP, TG, GR, in zone stats, structure, tops and lithology
  • Pick formation tops, and distinguishing members
  • Discuss variation in in lithology to enhance well placement
  • Make available knowledge of basin drilling difficulties
  • Discuss known solutions for geology related drilling issues
Remote Geosteering Services includes:
  • 24/7 two-man geosteering guidance from Columbine’s command center
  • Use of WellDirect software (or SES software as requested) to assist in saying in-zone, and on-plan
  • Monitor time critical changes to wellbore inclination and communicate with the operations geologist
  • 24/7 geosteering communications and availability to company geologists, directional drillers, and company man
  • Well to be correlated after every survey and lateral correlation shall be cross checked against formation after every survey
  • WellDirect (or SES) report to company geology team every six hours (or as requested) to include: standard data, geosteering geologist’s opinion of quality of current target, target adjustment suggestions, recommended direction changes (as necessary), and snapshot of the current interpretation.
  • Additional communication plan- calls to operations geologist from geosteering geologists
    • At least once per shift to discuss correlations
    • To alert possible problems such as change in Gamma or resistivity, significant formation dips, changes, or faults, day or night
    • With ANY questions or problems
  • Geosteering End of Well (EOW) report with entire well bore path, ROP, TG, GR, in Zone stats, structure, tops and lithology


Columbine Logging offers a wide variety of technology choices to keep our clients on the cutting edge of drilling science.  We are also continuously evaluating new instruments to add to our list of services.

Mass Spectrometry (Mass Spec)

Mass Spectrometry is an analytical instrument we use to provide advanced data beyond the C1–C5, CO2, and H2S provided from our Bloodhound.  The Mass Spec provides:

  • C1-C10 petroleum species; standard gas ratios
  • BTEX compounds and organic acids
  • Inorganics including N2, Ar, O2, H2O, CO2, He, and H2
  • Sulfur bearing compounds including SO2, COS, and CS2
  • Formation gas vs. drilling mud and additives
  • Bit generated gas
  • 90 second cycle time; 10 ppb sensitivity
  • Depth-based and time-based data
Calcimetry –

Experimental method used in many carbonate lithologies to determine the percent of limestone, dolomite, and non-carbonate rocks in the formation.


XRF = X-ray fluorescence for elemental analysis by on-site hand held instrument or laboratory testing.

XRD = X-ray diffraction elemental and mineral identification, including clay species, by laboratory testing.

Isotube/Isojar –

Isotube = In line gas sample collection method for advanced analysis of gases off-site.

Isojar = Method of cutting sample preservation for future testing off-site.

**Coming Soon – Chip gas analysis – On-site or laboratory method of extracting formation gases from chip samples.  This is used to more accurately identify the location of gas shows without interference from other sources.  **
