Frac crews have arrived this morning on the EOG Eagles Ranch 14H-1. It's very likely that it will be many weeks before an initial potential is posted on SONRIS. Be sure to "filter" through what you hear. Remember, rumors of 2200 bopd started BEFORE the frac job even started. Also, it will take six months to get comfort on the initial decline curve.  The presence of natural fractures in the Austin Chalk can create some chaos and unpredictability.

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.

Sentry (EOG) Eagles Ranch 14H-1 - Drilling Update

Sentry Energy Services (EOG) has completed the drilling process on the Eagles Ranch 14H-1. Note that a pilot hole was drilled before kicking out horizontally.  The drill times compare with the Louisiana Austin Chalk drilling phase that occurred in 2011.  A permit has been filed for the frac job. It sounds like 4288' will be the perf range.

Finally the rumors have started and the mineral buying speculators have shown up.  As always, they range from gusher to dry hole.  Always entertaining.

The first significant data point will appear 30-60 days after the frac job completes. Until then, we'll all have to be patient.  Note that this new Austin Chalk approach is different from the historical "naturally fractured" play. Review the prior posts regarding the Karnes Trough.
