..., azimuth) considering the uncertainties at survey stations using the RSS Model developed by the University of Stavanger. The TCO autonomously creates the well plan, controls the bit's deviation, and corrects the trajectory when it has diverged from the planned trajectory. The simulator can drill either 2D...

... seconds. This paper presents results of projections for four horizontal unconventional wells drilled in West Texas. Nearly 75,000 projections were generated on the four wells, validated with 839 survey stations, with median divergence of the projections from the nearest survey stations being less than one...

.... With the advanced spline curve method established, the uncertainty ellipsoid is calculated for each survey station for a set of wells on a multi-well pad. A Monte Carlo simulation using an industry standard error model for the survey measurements generated the uncertainty ellipsoids. The confidence interval...

Current three-dimensional well trajectory models represented by the minimum curvature method (MCM) tends to mathematically smoothen the wellpath between survey-stations creating an artificially low tortuosity expressed as dogleg severity (DLS). This can lead...
