Liquid Lift Method For Drilling Risers
US Patent:
2002011, Aug 29, 2002
Filed:
Feb 21, 2002
Appl. No.:
10/081054
Inventors:
Charles Dawson - Houston TX, US
Yuh-Hwang Tsao - Houston TX, US
Sandra Hopko - Katy TX, US
Yuh-Hwang Tsao - Houston TX, US
Sandra Hopko - Katy TX, US
International Classification:
E21B007/12
US Classification:
175/005000, 175/006000, 175/056000
Abstract:
A method for drilling a well below a body of water as disclosed which includes injecting into the well, at a depth below the water surface, a liquid having a lower density than a density of a drilling mud producing a mixture of drilling mud and low-density liquid in the well. The mixture of drilling mud and low-density liquid is withdrawn from an upper end of the well. The drilling mud and the low-density liquid are separated, with at least a portion of the separated low-density liquid returned to the depth below the water surface and at least a portion of the separated drilling mud returned to an upper end of the drill string.
