Solution Overview

Problem

Existing wellbore drilling methods require adjustments to the drillstring trajectory between stands, limiting the ability to correct deviations in real-time and leading to inefficiencies in wellbore drilling.

Innovation Solution

A system and method for detecting and correcting out-of-tolerance deviations in drill parameters during a stand using drill state data, including RSS, MWD, and LWD data, with real-time adjustments and alerts to optimize drill trajectory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If drillstring trajectory adjustments are made only between stands, then operational simplicity is maintained, but real-time deviation correction capability is limited and drilling efficiency decreases

Engineering Contradiction:
Improvedrilling efficiencyVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system continuously monitors drill parameters (azimuth, inclination, dogleg severity) and compares them against the planned trajectory, providing real-time feedback on deviations. This enables operators to detect out-of-tolerance conditions immediately and make corrective adjustments during the stand, rather than waiting for the next stand change, thereby improving drilling efficiency while maintaining operational simplicity through automated monitoring and alerting.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If real-time drill parameter monitoring and correction is implemented during a stand, then deviation correction capability is improved, but system complexity increases

Engineering Contradiction:
Improvetrajectory accuracyVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs self-monitoring and self-diagnosis by automatically comparing actual drill parameters against the planned trajectory and generating alerts for out-of-tolerance conditions. This self-service capability enables real-time trajectory accuracy improvement without requiring complex external monitoring systems, as the equipment monitors and reports its own performance status.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical trajectory adjustment mechanisms with electronic sensing and computational analysis. Instead of relying on mechanical systems to detect and correct deviations, the invention uses electronic sensors to monitor drill parameters and computational algorithms to compare actual vs. planned trajectories, reducing mechanical complexity while improving trajectory accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If continuous monitoring of drill parameters is performed during a stand, then deviation detection capability is improved, but data processing requirements and time consumption increase

Engineering Contradiction:
Improvedeviation detection accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system focuses monitoring efforts on critical parameters and out-of-tolerance conditions rather than continuously analyzing all parameters at full detail. When deviations are detected, the system rapidly processes the specific problematic areas while skipping routine parameter checks, thereby maintaining high deviation detection accuracy while minimizing overall data processing time consumption.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

A system for, and method of, drill deviation handling within a stand while drilling a wellbore are presented. The techniques include: receiving, by an electronic processor and during a stand, drill state data; comparing, by the electronic processor and during the stand, the drill state data to an active drill plan; detecting, by the electronic processor and based on the comparing, an out-of-tolerance deviation of a drill parameter; and providing, by the electronic processor, an alert of the out-of-tolerance deviation.
