Approach Provides Early Warning of Stuck Pipe

Stuck pipe caused by borehole uncleaning and wellbore geometry is a major issue in oil and gas drilling engineering. Existing research mainly focuses on machine learning and friction calculation for analyzing stuck-pipe trends. However, these methods often overlook key mechanism parameters contributing to stuck pipe, resulting in low accuracy. To solve these problems, a prediction method for drillstring-friction coefficient in tripping operations has been developed that can be used for early warning of stuck pipe.

Introduction

Currently, two primary categories of stuck-pipe-prediction approaches are used widely: knowledge-driven and data-driven methods.
