Drilling induced vibration causes production riser wear
Drilling Induced Vibration (DIV) is a relatively new field observed phenomenon. It is most likely to occur in narrow annulus drilling such as casing drilling or re-completion through a top-tensioned production riser. Most research was done by testing. An analytical procedure using a Multi-Tube riser modeling scheme was developed to assess quantitatively the DIV amplitude, bending moment and associated fatigue damage. The results coincide with field observations and tests. Field operations to avoid DIV are suggested. No published literature addressing the DIV issue was found. Most research was done by experiment and those test results are confidential and proprietary. The general consensus from researchers in the field is that: 1. DIV seems to occur only in tight-annulus risers, e.g., casing drilling or workover in the production riser. 2. DIV seems to occur only during drilling in hard formations, i.e., at very slow penetration rates.
