When drilling complex wells, such as those with long lateral sections, the friction forces become significantly high, which can<br>impede advancement of the drill string and reduce drilling performance. In these situations, Axial Oscillation Tools (AOT) could<br>be used to introduce an axial vibration to the drillstring. By locally reducing the friction forces, better transmission of weight to<br>the drill bit is possible and an increase in the rate of penetration occurs. However, to optimize the use of these tools, predictive<br>modeling is necessary to assess their effect on drilling characteristics.
