rl J. PETE 491 Project No. 3 Performed: 9/15/05 Submitted: 9/22/05 Student Summary of ‘Changing Chemophysical Properties of Formation and Drilling Fluid Enhances Penetration Rate and Bit Life’ The process of cuttings displacement from the drill bit-to-bottom hole interface has several factors associated with it. Drilling contractors’ attempts expedite this process have been known, by the author, to include the following common practices: 1. ‘Manipulation of weight on the bit’ 2. ‘Adjusting rotary speed’ 3. ‘Other variables other than changing the chemistry of rock and drilling fluid and their interaction.’ [1] These attempts may have success in several situations however it is the conclusion if the author that using and controlling several factors of the drilling fluids chemistry namely 1) reducing the surface tension within capillaries of the formation
