Colorado's Premiere Geologic Consulting Firm

With our thoughtful approach to operations geology, and our cutting-edge geosteering services, we remain focused on one simple ideal: how can we help our clients streamline their operations and improve their bottom line? From our central location we are able to serve clients in Colorado, New Mexico, North Dakota, Oklahoma, Kansas, Texas, Utah, and Wyoming; and our skilled consultants have experience in all of the major oil and gas basins in this region (Permian, DJ, Eagle Ford, Powder River, Williston, Arkoma, Anadarko, Ft Worth, San Juan, Piceance, Paradox, Uinta, and Green River). With all of our services we provide accurate, timely interpretations through our secure online reporting system so our clients can access their data anywhere, anytime using a computer or smartphone. We use Kingdom, StarSteer, and ZoneVu for mapping and geosteering.

ESA Analytics - Geologic Data and Analysis

ESA Analytics is a comprehensive data, visualization, and analysis package. We deliver clean, normalized, and QC'd well data, process it with Kingdom mapping software and Python scripts, and compile it into SQL databases, where it feeds into Spotfire visualizations and is ready for analysis. This cutting-edge system lets you skip the labor intensive and time consuming steps of data management and automates common workflows like generating gun barrel displays, making spacing measurements, and quantifying parent child relationships, so your technical teams can jump straight into other tasks like operations and development planning, competitor analysis, and evaluating acreage.
