Abstract: This paper proposes a design for a smart down-hole shock absorber that can read the magnitude and frequency of vibrations resulting from the drilling process. It then compares them to the recommended range of vibration that a bit requires to achieve the highest rate of penetration in a given formation with the slightest damage occurring to drilling equipment. Accordingly, the smart shock absorber changes its properties to damp the vibrations and make them fall into the recommended range of vibrations. The paper starts with a quick introduction about why shock absorbers are used in drilling for oil and gas. Next, we discuss different vibration problems that occur while drilling. Then we present the proposed design of the smart shock absorber. Finally, we discuss optimum placement of a shock absorber in the BHA.
