KEN BOEDEKER
Executive vice president, exploration & production
EOG Resources
Ken Boedeker joined EOG Resources in 1994, and has held technical and managerial
positions of increasing responsibility across multiple offices and functional areas within
the company. He was named EOG Resources' executive vice president, exploration & production, in December 2018 after serving as vice president and general manager in Denver
from 2016 to 2018, and vice president of engineering and acquisitions in 2015-16.
Boedeker holds a B.S. in petroleum engineering from the University of Wyoming.

EOG Adds Dorado Dry Gas
To Premium Play Portfolio

Q:

Let's begin with an overview of the Dorado
discovery. Please synopsize the sub-basin's

geographical location, geology and production characteristics, and EOG's acreage position. How many
Dorado wells have been drilled to date, and how
many drilling locations have been identified targeting
the Austin Chalk and Eagle Ford (or other prospective
intervals)? What are the total estimated potential recoverable reserves?
BOEDEKER: We are excited about this major new natural
gas discovery in the western Gulf Coast Basin. It is the latest
example of EOG's sustainable business model of organic exploration-driven resource expansion.
The Austin Chalk is what we call a hybrid play. That is, it
shares characteristics of unconventional and conventional reservoirs. We have found that hybrid plays react very well to our
horizontal completions technology.
Our current 163,000-net acre position in Webb County, Tx.,
is a combination of legacy acreage and new acreage captured
through low-cost, organic leasing, trades, and a bolt-on property
acquisition. We believe our position covers the majority of the
sweet spot of the play.
We completed our first two wells in Dorado in January
2019, targeting the Austin Chalk and the Eagle Ford. To further
delineate the play and collect more data, we completed 15 more
wells over the remainder of 2019.
We have identified an initial resource potential of 21 trillion
cubic feet net to EOG in the Austin Chalk and lower and upper
Eagle Ford formations: 9.5 Tcf in the Austin Chalk and 11.5
Tcf in the Eagle Ford. Dorado adds 1,250 net locations on fee

acreage to our premium inventory with 530 of those from the
Austin Chalk and 720 from the Eagle Ford.

Q:

Dorado is located in an area with a 100-year
production history. As EOG has described it,

Dorado was " generated from the bottom up " as an
outcome of its regional technical analysis of the
Austin Chalk trend. Looking at the genesis of the
play, how was the Dorado sub-basin identified? Walk
us through its evolution from an exploration concept
to ultimately getting the green light for development.
BOEDEKER: We first identified the potential of the Austin
Chalk formation as an oil play on top of our Eagle Ford
footprint back in 2016. We have since completed about 100
gross Austin Chalk oil wells in that area, capturing 59 million
barrels of oil equivalent of reserve potential net to EOG.
Shortly following that discovery, we began evaluating the
Austin Chalk formation in the Gulf Coast basin and identified
its potential as a dry natural gas play in Webb County. We
drilled 17 wells in 2019. We paused our drilling activity during
2020 to evaluate both the production results and the significant
amount of technical data we collected from cores, petrophysical
logs and 3-D seismic surveys. This data, including a year's
worth of production history from our drilled wells, has generated
a robust reservoir model, giving us confidence in our resource
estimates and projections for well performance.

Q:

What are the production profiles and estimated
EURs of the wells completed thus far? What
