SpecialReport: Drilling Technology
tools to determine where and how to drill
one-run Eagle Ford wells in Karnes and
DeWitt counties. After isolating the areas
in which one-runs should be attempted
and following prescribed parameters, the
one-run success rate more than tripled,
saving a substantial amount of time and
money across the drilling operation.
Running one BHA from surface casing
to TD provides a low-risk, high-reward
design option, since a failed one-run attempt requires a BHA trip at or near the
kickoff point before drilling the curve
and lateral, which is almost identical to a
two-BHA design.
Predictions based on BHA, parameters,
location and well length enable a high
success rate. Based on this study, using
these recommendations leads to a 91 percent accuracy rate in predicting one-run
success. Similar methods should be followed to determine precise recommendations for one-run success in other geographic areas.
