Abstract
System and method for determining an updated location of a bottom hole assembly (BHA) during drilling of a well are provided. During drilling, a computer system may receive tool face updates and may determine build rate estimates and a borehole depth increase during a toolface update period. The computer system may also calculate an updated estimate of the borehole position.
Claims20
A method for drilling a borehole from an updated borehole position, comprising:
- receiving, by a computer system, a first toolface update from a bottom hole assembly (BHA) located in a borehole during drilling of the borehole, wherein the first toolface update comprises a first toolface orientation of the BHA;
- estimating, by the computer system, based at least in part on the first toolface update, an estimate of a borehole position for the borehole;
- receiving, by the computer system, a second toolface update from the BHA located in the borehole during the drilling of the borehole, wherein the second toolface update comprises second toolface orientation of the BHA;
- calculating, by the computer system, an instantaneous build rate estimate;
- calculating, by the computer system, a borehole depth increase during a toolface update period that is a time period between the first toolface update and the second toolface update;
- calculating, by the computer system and responsive to one or more drill string compression, tension, and buckling, deviations in an overall drill string length;
- calculating, by the computer system, a plane of arc for a borehole curvature projection responsive to the second toolface update;
- calculating, by the computer system, a radius of arc for the borehole curvature projection responsive to the instantaneous build rate estimate;
- calculating, by the computer system, an updated estimate of the borehole position responsive to at least two of the second toolface update, the instantaneous build rate estimate, the borehole depth increase, and deviations in the overall drill string length;
- responsive to the updated estimate of the borehole position, adjusting, by the computer system, one or more drilling parameters for drilling the borehole;
- and
- drilling the borehole using the one or more adjusted drilling parameters.
