Removing cuttings from deviated and horizontal wells

Sandoiu Gheorghe-Florin


Effective cuttings transport is critical in drilling production horizontal and extended reach wells. In these cases, failure to remove drill cuttings from the hole would lead to deposition and accumulation of cuttings in the annulus, resulting in stuck pipe, eccentric annulus and/or reduced penetration rate.
