EOG - Austin Chalk - Colorado County, TX

EOG has taken a similar "stealth" approach in Colorado County, Texas as they have recently in Louisiana. On March 27, the company spud an Austin Chalk well, the Pallas Energy Services LLC Tonkawa Unit #1. It has a permitted total depth of 16500'.  In Avoyelles Parish, their well was permitted under Sentry Energy Services LLC.

The Tonkawa well is located in the southern deep part of the very prolific Giddings Field. The maps below illustrate that EOG's well is on trend with some of the most prolific gas producers in the play. In contrast to the Karnes Trough, they appear to be targeting a much higher GOR in Colorado County.  Their well is in the "bullseye" of the most active leasing over the past 90 days.  Everyone likes to chase EOG.

Most importantly, the log signature is very similar in all three of their project areas: Karnes, Colorado, and Avoyelles/St.Landry/Pt. Coupee Parishes, Louisiana.  The cross section below illustrates two wells from Colorado County and Avoyelles Parish.  While 293 miles apart, the Passey log display presents very similar log signature with very comparable Passey values.  The high TOC thicknesses (DLogR > 1.0) of 174' and 180' represent a very attractive target for a high proppant frac job. The mean DlogR values are also very similar. Results from these two "Energy Services" wells will be very important for both areas.
