Casing Drilling Manages Shallow-Gas Risk in Brownfield Redevelopment
Publication: Journal of Petroleum Technology
Publication Date: 01/01/2013

Casing drilling was used to optimize drilling of the tophole section in the Phase-1 wells of the mature Samarang field redevelopment campaign. Lost-circulation and stuck-casing incidents in the surface section had occurred in previous campaigns, and casing drilling was identified as a solution to mitigate these problems. This study focused on the casing drilling application to reduce the risk of a shallow-gas blowout.
