Plan the well from the ones already drilled.
Ingest the offset wells around your location, ranked by how well they match, and carry their outcomes and lessons into the program: ROP, ECD and dysfunction expectation bands calibrated to measured results, not assumptions.
The offsets around your well.
Every offset within the search radius, placed by direction and distance and colored by outcome (clean runs, trouble zones and major-loss wells), each with its Offset Match Index against the planned well.
Ranked by how well they match.
Candidate offsets scored on a match index and weighted by formation, section, basin, trajectory, field and hole size, with TD days, ROP, NPT, cost per foot and the outcome for each, so expectation bands are built from comparable wells.
The lessons, carried into the plan.
Hazards logged on nearby wells (losses, stuck pipe, drag, stability, hole cleaning), with the depth zone, priority, approved mitigation and the offset each came from. Pin any lesson to the program so it travels with the well.
Hydraulics, hole cleaning and torque & drag.
One shared model from the accepted mud program, BHA and trajectory, with the operating window and the limiting point named on every chart.
ECD against the pore–frac window, with the guard band and casing shoe marked.
Required flow versus ROP, capacity by depth and the cuttings-bed profile.
Hookload and surface-torque broomsticks against equipment limits, WOB × RPM operating window.
