Guardian Oil & Gas, Inc. retains mineral rights leases throughout the continental United States. However, most of our drilling and production projects are in Texas and Louisiana. Guardian is very active in the East Texas Austin Chalk play and has pursued oil and gas there since 2003 when we joined Anadarko in their 34,000 acre play in Tyler County. Since then, we have participated in more than 50 Chalk wells in Tyler, Polk, Grimes, and Burleson Counties of Texas and in Rapides and Evangeline Parishes in Louisiana. Greatly improved technology has allowed exploration companies to exploit and develop underexplored plays in the Austin Chalk. Most Chalk wells have one or more laterals that extend out horizontally into the Chalk reservoir. The laterals may be as short as a thousand feet or may extend more than five thousand feet from the vertical part of the well. Because the Chalk is a tight reservoir with low permeability, hydrocarbon production from the Chalk relies on natural fractures. The horizontal parts of the well bore intersect more fractures than a vertical hole through the Chalk, increasing the productivity of these wells. Guardian has partnered with several operators to drill a series of horizontal wells targeting the James Lime. This Lower Cretaceous transgressive limestone is part of the Glen Rose Formation. The James Lime lacks the natural fractures of the Austin Chalk and must be artificially fractured in order for the wells to be productive. Most of this activity is centered in Nacogdoches, Shelby, and northern San Augustine counties. Guardian has interests in a number of wells in East Texas that produce from the Cotton Valley and Travis Peak formations. Guardian participates in drilling projects in the Mississippian and Pennsylvanian reservoirs in north central Texas. |
