The system consists of two components, a HydraHemera™ Jetting Tool and a HydraHemera™ Cementing Tool.
The HydraHemera™ Jetting Tool is used to wash and clean out debris in the annuli behind perforated casings. It features jet nozzles which are positioned at irregular angles and engineered for optimum configuration and exit velocity. The jets penetrate and clean thoroughly behind multiple perforated casings.
The HydraHemera™ Jetting Tool ensures optimum conditions in the casing annuli prior to placing the plugging material in the cross section. Debris, old mud, barite and old cuttings are replaced by clean mud.
Using a ball drop mechanism after jetting, the HydraHemera™ Cementing Tool is activated, and combined with the HydraArchimedes™ tool enable placing plugging material in the entire cross section of multiple annuli, and hence, establishing a proper barrier in the well for P&A or sidetrack purposes.
The HydraWash™ tool is connected to TCP guns and the workstring. When running in hole, full circulation through the HydraWash™ tool is possible and hence, tripping speed is determent by the TCP gun supplier.
After TCP perforation, the washing feature is activated by dropping a ball that closes off the bypass channels. The perforated interval is washed as per detailed HydraWell Intervention washing procedure until sufficient pumping rates are achieved.
A larger ball is dropped to activate the hydraulic release system that separates the HydraWash™ Jetting Tool from the Cement Stinger.
