At-the-Bit Mud Loss Control-Drilling Piloting, Tool Material Upgrading and New Payload for OBM

Offentlig prosjektsammendrag

The At-the-Bit Mud Loss Control® technology is a unique solution for on demand and early control of mud loss during drilling. Such losses may lead to high drilling costs and HSE challenges. The technology comprises of a downhole tool carrying a chemical payload for sealing of lossy formations when intersected by the drill bit. The tool is mechanically robust to withstand harsh drilling environments and is mechanically operated and controlled by the dropping of steel balls . The circulating drilling mud will displace the chemical payload from the annulus of the tool and into the wellbore. Several modular and stacked payload carrier subs can be used depending on the severity of the mud loss. A new special and engineered superabsorbent polymer gel has been developed for use in high salinity water-based drilling mud systems. Research is ongoing for developing a suitable oil absorbing polymer for use with OBM.
