A method of drilling a wellbore to a target includes measuring attitudes at two adjacent survey stations along a wellbore using a downhole surveying tool. An actual change in wellbore position over a survey leg linking the two survey stations is determined. Corrections are applied to the measured attitude at one or both of the survey stations such that a modeled well path joining the survey stations reflects the determined actual change in wellbore positon between the two survey stations.

A system and method of drilling a wellbore to a target may include measuring attitudes at two adjacent survey stations along a wellbore using a downhole surveying tool. An actual change in wellbore position over a survey leg linking the two survey stations may be determined. Corrections may be applied to the measured attitude at one or both of the survey stations such that an estimated well path joining the survey stations indicates the determined actual change in wellbore position between the two survey stations.

A method and system for geosteering may generate a misfit function using a spline function. The misfit function may be used to accurately map errors or differences between TVD-based measurement data for one or more reference wells and MD-based measurement data collected during drilling of a subject well, in order to accurately determine a stratigraphic location of the subject well.

Analysis and control of drilling mud and additives is disclosed using a mud analysis system and a mud additive system that may automatically monitor and control the drilling mud during drilling of a well. The mud analysis system may acquire measurements on a sample of the drilling mud during drilling, and may send signals indicative of the drilling mud to a steering control system enabled to control the drilling. The steering control system may receive user input or may make decisions regarding additives to be added to the drilling mud and the timing thereof. The mud additive system may be enabled to receive commands from the steering control system and mix and add additives to the drilling mud.

A method and system for simulating reservoir recovery include taking into account inaccuracies in well spacing due to wellbore positional uncertainty.
