Mud Logging

The hydrocarbon log is one of the most important sources of subsurface information, requiring accurate and experienced gathering of data. For that reason, it is important to use a company whose major emphasis has been to acquire qualified, professional personnel and to maintain modern, dependable equipment.

  • Continuous gas monitoring on mud or air system.
  • Chromatograph analysis of total gas (C1 to C5).
  • Lithology identification and complete description including show characteristics such as visual porosity, stain, fluorescence, and cut. Lithology is plotted on log using two columns, interpretive and percentage.
  • Connection and Trip Gas.
  • New and old bit information, including type, footage, and total hours run.
  • Rig mechanics such as Weight on Bit, RPM, Pump Pressure, and Strokes per Minute.
  • Mud data will be recorded each day at the depth checked by mud engineer.
  • Directional survey test data.
  • Lag calculation and correction, gas readings and samples lagged to correct depth.
  • Penetration rate, plotted in minutes per foot or feet per hour.
  • Log of all data listed above sent to client and partners on a daily basis. Detailed log to be plotted on a 5" = 100' scale and strip log to be plotted on a 1" = 100' scale as requested.
  • Complete morning reports communicated to the client immediately containing all pertinent well conditions and evaluations of each hydrocarbon show.
  • Show analysis reports called to the operator at a time specified by the client.
  • Show analysis reports communicated to the client immediately containing all pertinent well conditions and evaluations of each hydrocarbon show.
  • Our computer service uses the WellSight software. Data from our equipment is directly downloaded into the log. The daily log and strip log can be emailed directly to the customer and partners. The morning report and show reports can also be emailed at the customer's convenience.
  • We are able to email and receive email at the well site.

standard service

Wildcat's one man unit utilizes the same equipment and offers a logging engineer on duty as the hole dictates (an average of eight hours / day), adjusting to customer convenience and drilling operation. Rig crews will furnish samples unless previous arrangements have been made.

full service

Provides a logging engineer to live on location while drilling operations proceed. Multiple reports and updates will be sent out during the day as requested. Logger will be available throughout to answer and questions and maintain the gas detection equipment. Rig crews will furnish samples.

Two-man service

Two-man service offers continuous sample and hydrocarbon analysis by two experienced logging engineers. Multiple reports and updates will be sent out during the day and night as requested. A logger will be on duty 24 / 7 to answer any questions and continuously monitor the gas detection equipment. Samples will be collected by the mud logging crew.
