Shale Cuttings Analysis Pete 493 Project #3 Date Conducted 10/08/09 Date Submitted 10/15/09 Objective To analyze the properties of cuttings for the purpose of understanding the interaction of well bore fluid properties and the formation being drilled. Introduction The cuttings were retrieved from the shaker after being separated from the drilling mud. Each sample of cuttings can allow the determination of downhole conditions at which the hole is being drilled. Discussion Sample One

Shale Cuttings Analysis Pete 493 Project #3 Date Conducted 10/08/09 Date Submitted 10/15/09 This sample was retrieved off of the shaker by Dr Hayatdavoudi after he heard a loud banging noise coming for the drill pipe. These cuttings caused stuck pipe. When cuttings of this nature are encountered you should treat your mud accordingly to fix your problem. Sample Two This is a result of treated mud due to packing. Certain chemicals were introduced to the drilling fluid which had cuttings that resembled sample one and forced compaction of the

Unformatted text preview: particles instead of diffusion. If diffusion would occur then a gummy type of fluid would be produced and result in stuck pipe. Shale Cuttings Analysis Pete 493 Project #3 Date Conducted 10/08/09 Date Submitted 10/15/09 Sample Three These cuttings are very linear in shape and when found on the shaker they are parallel to each other. Sample Four Shale Cuttings Analysis Pete 493 Project #3 Date Conducted 10/08/09 Date Submitted 10/15/09 When these cuttings are encountered on the shaker this is a good sign of everything working appropriately. These cuttings will lightly bounce along the shaker. Conclusion Paying attention to the cuttings on the shaker is vital to well bore stability. When analyzing the cuttings you can make corrections to your drilling fluid by adding appropriate chemicals to divert any problem that may occur. This ultimately will save the company time and money....
