The Ardyne developed ART - Ardyne ReSonance Tool - enables the pulling of casing with resonance assist. Dynamically amplified vibration is transferred to the stuck casing through a casing spear in order to vibrate the settled solids, reducing the bond strength and friction. Therefore reducing the required pulling force to free the stuck object.
When the ART is combined with the already successful TITAN® System it enables a high jacking load to be simultaneously applied, the combination of amplified vibration and high jacking forces combine to allow the maximum probability of casing recovery. With the additional benefit of being able to cut casing without tripping back to surface the TITAN RS® System virtually guarantees casing on deck every time.
The ART can be mobilised in a variety of BHA combinations with other Ardyne proprietary technology, allowing it to be run with various additional features.
From pulling with a casing spear up to the full TITAN RS System (which enables wellbore clean-up, casing cutting and jacking alongside resonance), there are different combinations to fit varying operations. These combinations can be viewed here:
The below video provides information behind resonance, how it is applied in this scenario and the forces it can generate to enable longer sections of casing to be recovered while stuck in settled solids.
