System and method for detection of slide and rotation modes
First Claim
1. An apparatus, comprising:
- a slide estimator of a surface steerable system of a drilling rig for generating information relating to slides responsive to externally monitored data;
wherein the slide estimator can detect whether a borehole assembly (BHA) connected to the drilling rig is in a slide mode of operation or a rotary mode of operation responsive to the externally monitored data;
wherein the slide estimator detects a slide mode responsive to detection of a flow rate of drilling mud, a stationary BHA and an on bottom condition of the BHA; and
wherein the detection of the flow rate of drilling mud is determined by detection of a standpipe pressure exceeding a standpipe pressure circulation threshold.

Abstract
A system and method for surface steerable drilling are provided. In one example, the method includes monitoring operating parameters for drilling rig equipment and bottom hole assembly (BHA) equipment for a BHA, where the operating parameters control the drilling rig equipment and BHA equipment. The method includes receiving current inputs corresponding to performance data of the drilling rig equipment and BHA equipment during a drilling operation and determining that an amount of change between the current inputs and corresponding previously received inputs exceeds a defined threshold. The method further includes determining whether a modification to the operating parameters has occurred that would result in the amount of change exceeding the defined threshold and identifying that a problem exists in at least one of the drilling rig equipment and BA equipment if no modification has occurred to the operating parameters. The method includes performing a defined action if a problem exists.

11. A method for detecting slide modes and rotary modes of a borehole assembly connected to a drilling rig, comprising:
-
monitoring at least one well sensor parameter associated with the drilling rig; detecting within a slide estimator associated with a surface steerable system for the drilling rig whether a borehole assembly (BHA) connected to the drilling rig is in a slide mode of operation or a rotary mode of operation responsive to the monitored at least one well sensor parameter; controlling the operation of the drilling rig responsive to the detected slide mode or rotary mode of operation; wherein the step of detecting further comprises detecting a flow rate of a drilling mud, a stationary BHA and an on bottom condition of the BHA; and wherein the step of detecting the flow rate further comprises determining whether a standpipe pressure exceeds a standpipe pressure circulation threshold. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for detecting slide modes and rotary modes of a borehole assembly connected to a drilling rig, comprising:
-
monitoring a plurality of well sensor parameters associated with the drilling rig; detecting within a slide estimator associated with a surface steerable system for the drilling rig whether a borehole assembly (BHA) connected to the drilling rig is in a slide mode of operation or a rotary mode of operation responsive to the monitored plurality of well sensor parameters, wherein the step of detecting further comprises; detecting a flow rate of drilling mud, a stationary BHA and an on bottom condition of the BHA to determine whether the BHA is in the slide mode or the rotary mode of operation; and determining the slide mode of operation or the rotary mode of operation; and based upon occurrence of one or more of these conditions; controlling the operation of the drilling rig responsive to the detected slide mode or rotary mode of operation; wherein the step of detecting the flow rate of drilling mud further comprises determining if the flow rate of the drilling mud exceeds a predetermined flow circulation threshold; and wherein the step of detecting the stationary BHA further comprises the step of detecting a surface rotary speed less than a rocking threshold value. - View Dependent Claims (22)
