Continuous hydrocarbon gas monitoring, real-time data transmission, and expert remote oversight designed to improve safety, reduce field staffing demands, and support faster drilling decisions.
Reliable gas monitoring is essential for understanding hydrocarbon response, recognizing formation changes, and identifying conditions that may affect drilling safety or well performance.
Selman Geo Services provides professional Remotely Monitored Gas Logging Services that combine advanced wellsite instrumentation with secure, real-time data transmission and experienced geological oversight.
This approach allows operators to maintain continuous visibility into gas levels and drilling conditions while reducing the number of personnel required at the wellsite. Your field and office teams receive timely updates that support faster decisions, better communication, and more efficient operations.
Remote gas logging is the continuous measurement and transmission of hydrocarbon gas data from the wellsite to qualified professionals working from another location. Gas detection equipment remains at the rig, while incoming readings are reviewed and interpreted in real time.
Unlike a basic automated system, professional Remote Gas Logging includes human oversight. Experienced personnel evaluate gas trends alongside available drilling information so operators receive useful interpretation rather than a stream of isolated numbers.
Traditional gas logging can require additional personnel and accommodations at the wellsite. Remote monitoring gives operators another option when project conditions, staffing goals, or cost controls make a reduced on-site footprint desirable.
Remote Gas Logging Services may help operators:
The result is a more flexible operating model without giving up access to critical wellsite information.
Accurate Hydrocarbon Gas Detection helps drilling teams identify gas-bearing formations, evaluate hydrocarbon response, and recognize unusual well conditions.
Depending on project requirements, gas monitoring may include:
Our remote team reviews how readings change over time and how those changes relate to formation, drilling activity, and other available well data.
Gas readings become more valuable when they are interpreted with other operational information. Selman Geo Services can evaluate Real-Time Drilling Data alongside gas response to help distinguish geological changes from routine drilling events.
Relevant information may include:
This broader context supports more reliable interpretation and gives the project team a clearer understanding of what is occurring downhole.
Unexpected gas behavior can be an important indicator of changing well conditions. Continuous monitoring helps identify abnormal trends early enough for the appropriate personnel to evaluate the situation.
Remote gas logging can help draw attention to:
Remote monitoring does not replace well-control procedures or the responsibilities of the drilling team. It provides an additional stream of timely information that can support safer operational awareness.
Reducing the on-site personnel requirement can lower costs associated with travel, housing, transportation, and field logistics. It can also simplify operations in locations where space or accommodations are limited.
Because data can be reviewed from a centralized location, remote personnel may also support multiple operations more efficiently while maintaining consistent monitoring practices.
Automated alarms can identify when a reading crosses a predetermined threshold, but they do not always explain why the change occurred or whether it is geologically meaningful.
Selman Geo Services combines technology with experienced oversight. Our professionals review gas trends, drilling activity, and available geological information to determine when a change deserves attention.
This human interpretation helps reduce unnecessary alarm fatigue while improving the likelihood that meaningful changes are communicated promptly and clearly.
Remote reporting helps engineers, geologists, drilling supervisors, and management access the same current information. When meaningful changes occur, our team communicates the relevant observation and context so the appropriate decision-makers can evaluate the next step.
Remote gas monitoring can be adapted to different project types, operating models, and reporting requirements.
Monitoring frequency, reporting procedures, communication protocols, and data requirements can be customized around the operator’s needs.
Selman Geo Services combines advanced gas-monitoring technology with practical geological and drilling experience. Our remote services are designed to provide dependable information, clear communication, and responsive support throughout the operation.
Our team understands that remote monitoring must be dependable, responsive, and connected to the realities of drilling operations. We provide more than software access—we provide experienced oversight and practical support.
They combine wellsite gas-detection equipment, real-time data transmission, and remote professional oversight to monitor hydrocarbon gas levels during drilling.
No. Required rig and safety personnel remain on site. Remote gas logging can reduce the need for dedicated gas-monitoring personnel to be physically present at the well.
Monitoring may include total gas, background gas, connection gas, trip gas, gas chromatography, hydrocarbon composition, and gas trends by depth.
Gas readings are transmitted from wellsite equipment to authorized remote personnel and may also be made available to designated field and office team members.
Yes. Depending on project requirements and system capacity, centralized remote monitoring can support multiple drilling operations.

Posted on Google heather grigsby Posted on Google Kristie Ferguson We recently used Selman Mudlogging on two wells in the Texas Panhandle, and they absolutely exceeded expectations. Their team was consistently on time, professional, and extremely reliable. With their Starlink setup, communication was seamless—no downtime, no delays, and always reachable when needed. Their daily reports were clear, timely, and dependable. Our mudlogger was highly knowledgeable and did an excellent job analyzing samples and identifying shows in new zones, which added real value to the project. The accuracy and attention to detail were outstanding. Selman’s online portal and mobile app make accessing sample analysis, uploads, and reports incredibly convenient. Everything is organized, easy to navigate, and available in real time. Overall, they were very easy to work with, extremely competent, and clearly dedicated to delivering a top-tier service. We’ll definitely be using Selman Mudlogging on future jobs. Highly recommended.Posted on Google Ross Evans I’d like to take a minute and provide a review of this awesome company a Permian/North Texas operator’s view point due to how happy we’ve been with working with this company. This company deserved a detailed review post! I personally have to say, that this has been my favorite logging company that has logged for us at Joint Resources and that I’ve worked with to date. I’ve been managing the mud logging operations for over 12 years at my company and have worked with numerous companies in the Permian and North Texas regions, and this company has been on point all across the board from, all the way from customer support to operations in the field as well as giving the best performing gas detection system and post well logs I have worked with. They have the most competitive pricing on the market and offer a simple pricing structure. Tom Selman does not believe in charging operators a million different fees like most other logging companies do (logger travel mileage, fees for printing post well logs, daily logger per diem/lodging fees, etc) and the base logging package is very fairly priced and beats any other operator’s pricing that we’ve used. They offer premium gas detection services as well as a first of it's kind service that I personally have never come across before. Two different things that Selman offers that I have not found another logging outfit to offer: (1) A photo log that includes BOTH high quality images of the samples AND images of the florescence shows for each of the samples recorded! This was an extremely valuable log to have post well when planning the completions! I can't even begin to tell you how cool it was to have images of the fluorescence and shows after the well, normally this is only recorded as descriptions from the Mud Logger's and having the images completely takes out the human error component/chance loggers may miss recording a good show. (2) A patented gas detection manifold that Selman offers to be welded in place at the flow line that reads the gas before it gets circulated through the possum belly. Selman included this service for free and provided the manifold set up/bull plugs and coordinated with the welder in person before the well. We tested this set up alongside the normal gas agitator set up and found it to read much higher gas readings than the agitator post-circulation readings! We’ll most definitely be using this set up on all of our future wells. This company also is equipped with Starlink services and live stream every sample live through the drilling process to its own in-house app which was really nice for the team and management to view both in the field and remotely back at the office. You get to see actual images live streamed into the app plus the mud log and gas readings which is huge. It keeps everybody in the loop. An added bonus was being able to speak firsthand with the owner Tom Selman at any time he is an extremely talented and motivated owner of this company and has instilled great standards and how his company has ran in his team goes by. Tom’s leadership at this company has really brought this team to a high standard of logging and we really appreciate that when we use them.
