In-situ analysis of drilling fluid solids during wellbore drilling

A non-transitory computer-readable medium storing instructions executable by one or more processors to perform operations comprising:

• receiving, by one or more processors, at least one of images or measurement data captured by a digital imaging system coupled to a shale shaker of a wellbore drilling assembly, the shale shaker positioned at a surface of the Earth adjacent a wellbore and configured to receive a drilling fluid comprising a mixture of wellbore drilling mud and solid objects found in the wellbore while drilling the wellbore through a subterranean zone, the digital imaging system configured to capture at least one of images or measurement data of the solid objects when the drilling fluid is received by the shale shaker;
• classifying a type of the solid objects selected from a group including drill solids and non-drilled solids;
• determining one or more properties of a target solid object of the solid objects, the one or more properties comprising at least one of specific gravity or composition of the target drill solid;
• storing pre-determined properties of the solid objects;
• and
• comparing the one or more properties of the target solid object with the pre-determined properties of the solid objects.
