Integrated Work Flow Mitigates Drilling Vibrations

Fig. 1—Notional drilling-dysfunction domains.

A work flow that combines optimization of the drillstring and bottomhole-assembly (BHA) design during well planning and then applies advanced surveillance tools to a well-trained drilling crew yields reduced vibrations and higher drilling rates. This methodology is based on the premise that an efficient drilling operation requires optimized tool designs, advanced diagnostics using real-time drilling parameters, and on-site training of efficient drilling practices and the proper use of rig-control systems.

Introduction

In recent years, as part of a limiter-­redesign process and rate-of-penetration (ROP) optimization effort, the operator has sought to develop and validate in the field a suite of tools specifically directed toward drilling-operations support. Vibration-mitigation efforts are a subset of the entirety of this broader program.

BHA redesign involves planning to change the downhole tools. Once a BHA has been selected and its rotary-speed sweet spot is known, there is a real-time component as the driller determines how good the sweet-spot prediction might be or if an alternative operating condition is preferred.
