History of San Juan Gas

The San Juan Basin is one of the most prolific gas producing regions in the country, located in northwestern New Mexico and southwestern Colorado. It is roughly a circular area of about 15-20 thousand cubic miles of sedimentary rock. San Juan Basin produces approximately 70% of gas in New Mexico. In the year 2003 alone around 1.1 mmcf of gas was produced from about 29,000 wells. These wells range in depth from 2,000 feet to over 7,500 feet.

The major producing formations in this basin are the Dakota, Mesa Verde, Pictured Cliffs and the Fruitland coal. Current remaining recoverable reserve estimates for northwestern New Mexico are 12.9 Tcf. The development of the Fruitland coal seam resource starting in 1988 dramatically changed this basin. Currently, almost 65% of the total production from this basin is from this one resource.
Project Outline

The PRRC's Industry Services and Outreach Group was funded for the DOE project DE-PS26-04NT42072-1 (Round 2) ³Petrophysical Analysis and Geographic Information System for San Juan Basin Tight Gas Reservoirs², to build a database of well and core information for the San Juan Basin. The project, originally funded for two years but extended for a third year, will increase the availability and ease of access to data concerning the Dakota and Mesa Verde tight gas reservoirs of the San Juan Basin.
