Laboratory Drill Rig Design for Bit Wear & Vibration Study

Drilling operations is a costly operation and any factors that contribute to the delaying of work operation would be unwanted by the industry. Among the many factors that contribute to problems are bit wear and vibration. Besides currently there are no real time monitoring of bit wear in the oil and gas industry. The main objective of this project here is to design a safe laboratory scale test rig that is capable of assimilating the actual drilling operations and conditions out in the field. Thorough study of material selections and decision making processes such as the weighted evaluation matrix and also analytic hierarchy process (AHP) are used in order to complete the study and thus providing a proper conceptual design of the laboratory scale test rig. A design concept is also generated together with general static analysis of the designed concept. With the lab scale test rig, studies on the bit wear and also vibrations could be done and thus further optimization of drilling practices could be done at a lower cost rather than practicing out in actual drilling operations. This work would illustrate the advantages of varying the parameters for better drilling results in the oil field.
