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.
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
PRRC's Industry Services and Outreach Group will be
working on the “Petrophysical Analysis and Geographic
Information System for San Juan Basin Tight Gas Reservoirs”,
a project recently funded by the U.S. DOE to build a
database of well and core information for the San Juan
Basin. This 2-year project seeks to increase the availability
and ease of access to critical data on the Mesaverde
and Dakota tight gas reservoirs of the San Juan Basin.
Upon completion, the data will be available as a simple
intuitive user interface as a standalone version or
on the internet via this website, enabling users to
query, view, export/import data in various data formats.
