Solution Overview

Problem

Existing wellbore drilling systems lack efficient and automated methods for analyzing and classifying drill cuttings and non-drilled solids, relying on manual visual inspection which is time-consuming and prone to errors, and do not provide real-time insights into drilling conditions.

Innovation Solution

A system comprising a digital imaging device mounted on a non-vibrating member of a shale shaker, coupled with a computer system, uses image processing and deep learning techniques to classify drill cuttings and non-drilled solids based on geometric attributes and drilling parameters, providing real-time monitoring and condition assessment.

AI summary

Analysis of drilling slurry solids by image processing includes receiving images of a solid slurry including a mixture of wellbore drilling mud and solid objects found in the wellbore while drilling the wellbore through a subterranean zone. The solid objects include drill cuttings and non-drilled solids. By implementing image processing techniques on the images, the solids in the solid slurry are classified a drill cutting or as a non-drilled solid.
