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.

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. Thanks to everyone at Selman and Associates – keep up the great work guys, Ross Evans, Geologist - Joint Resources
