AI-Assisted Geosteering

In one sentence

Keeps the horizontal well inside the target layer by continuously re-matching the measured logs to the geological model.

The problem

Geosteering is a continuous interpretation task performed under fatigue on a twelve-hour shift. Interpretations diverge between shifts, and the well pays for the disagreement in reservoir contact.

Manual correlation with the type log is slow enough that by the time the picture is clear, the bit has already drilled past the decision point.

How it works

Measured gamma and resistivity are matched against a stratigraphic type log by elastic correlation, solving continuously for structural dip and relative stratigraphic position. Multiple hypotheses are carried forward with probabilities rather than collapsing to one interpretation early.

Directional recommendations are advisory; the steering decision stays with the geosteerer and the directional driller.

Data required

  • LWD gamma, resistivity and where available azimuthal density/image
  • Offset type log and the structural model
  • Continuous inclination and azimuth, survey and projection to bit
  • Reservoir target envelope from the well plan

What you get

  • Live stratigraphic position with alternative interpretations and probabilities
  • Suggested inclination adjustment with the expected reservoir-contact gain
  • Post-well geosteering report with the final interpreted well path in the model

What it cannot do

This is frontier. In a layer-cake reservoir with distinctive markers it works well; in a heterogeneous or faulted target with a weak gamma contrast it produces ambiguous interpretations, and it will say so rather than choosing confidently. It does not replace the geosteerer and is not deployed in closed loop with the rotary steerable system.

Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
