EOG in the Eagle Ford Oil Window?


It is no secret that EOG is drilling in the Eagle Ford, despite Mark Papa stating in the fourth quarter earnings call that “we have got a policy of not commenting on any of our horizontal oil activities where we are still leasing acreage.”  With that being said, lets dive into the Drilling Info database to see what EOG is doing out there.

Below is a map of the EOG well locations in the Eagle Ford area that have spud since 2009.  There are 32 wells spud spread across 6 counties from Webb to Gonzales.  The clusters appear to be in the same relative structural zone in the more downdip portion of the play.

The map below is a zoomed shot of the cluster in NE Karnes county labeled with well type and spud date.  EOG has repeated this pattern in each of their clusters so far.  They have a series of parallel NW SE trending horizontal wells with one or two offset vertical wells.

The next step in sifting through this data might be to look what completion and production data is available.  On the production front, there is currently only one producing lease.  Below is the production chart . The cumulative oil production is 48,407 bbls and 49,254 Mcf as of 12/09.  There are two wells on this lease, which may explain the spike in production after it resumed production.

As far as completions go, only well record oil completions have been filed which omit all the juicy information such as volume/day, oil gravity, and frac stage info.

So is there anything else we can infer based on the available data? Well it is just speculation, but it looks like EOG may be setting up for simulfrac operations.  Drilling Info has done some simulfrac studies in the Fort Worth basin and EOG is a technological leader in this field.  A simulfrac is when two or more somewhat parallel wellbores are frac’ed at relatively the same time.  Sometimes operators use vertical offset wells to monitor the interaction between wells which may explain the vertical offsets within these clusters. In fact, 3 of the 8 vertical EOG wells here say monitor well in the completion form.  The relative cost difference of simulfrac operations is minor and the production efficiency is greater.

However, until more data is available, this is just speculation.  Regardless, we here at Drilling Info – Energy Strategy Partners will be keeping a close eye on all Eagle Ford industry activity.
