INTEGRATED WELL SURVEY MANAGEMENT AND PLANNING TOOL Russian patent published in 2018 - IPC E21B44/00 E21B47/22 G06F19/00 

FIELD: mining.

SUBSTANCE: invention relates to an integrated well survey management and planning tool. Tool can receive a trajectory of a proposed well from a surface to a subterranean geological target, to be reached by drilling the well, and a survey plan indicating the number, position and survey type of surveys, to be performed on the well while drilling the well. Tool can apply multiple error models based on the survey types for drilling the well. Each error model defines a respective uncertainty in reaching the subterranean geological target by drilling the well along the received trajectory. Tool can display, in a user interface, the received trajectory of the well and an uncertainty indicator determined by applying the multiple error models. Uncertainty indicator represents a combination of respective uncertainties defined by the multiple error models and indicates an uncertainty in drilling the well on the received trajectory.

EFFECT: complex integrated well survey management and planning tool is proposed, which is implemented using a computer system.
