Abstract
A method of managing pressure in a wellbore having an annulus defined between a wall of the wellbore and a work string that includes drill pipe, a service tool, and a lower completion, the method comprising: performing the following operations, running the work string in hole down the wellbore while maintaining an annulus pressure while maintaining a hydrostatic pressure within the work string above a valve of the service tool, wherein the valve is configured to pressurize the annulus without pressurizing the work string.
Claims25
A method of managing pressure in a wellbore having an annulus defined between a wall of the wellbore and a work string that includes drill pipe, a service tool, and a lower completion, the method comprising:
- performing the following operations,
- running the work string in hole down the wellbore while maintaining an annulus pressure while maintaining a hydrostatic pressure within the work string above a valve of the service tool, wherein the valve is configured to pressurize the annulus without pressurizing the work string.
A method comprising:
- managing pressure in a wellbore having an annulus defined between a wall of the wellbore and a work string that includes a drill pipe, a service tool and a lower completion, wherein managing the pressure in the wellbore comprises,
- performing the following operations,
- running the work string in hole down the wellbore while maintaining an annulus pressure in the annulus while maintaining a hydrostatic pressure within the work string above a valve of the service tool, wherein the valve is configured to pressurize the annulus without pressurizing the work string wherein the valve is closed during the running of the drill pipe, the service tool, and lower completion in hole down the wellbore.
A method comprising:
- managing pressure in a wellbore having an annulus defined between a wall of the wellbore and a work string that includes a drill pipe, a service tool and a lower completion, wherein managing the pressure in the wellbore comprises,
- performing the following operations,
- running the work string in hole down the wellbore while maintaining an annulus pressure in the annulus while maintaining a hydrostatic pressure within the work string above a back pressure valve of the service tool, wherein the back pressure valve is configured to pressurize the annulus without pressurizing the work string, wherein the back pressure valve is above a crossover port of the service tool that is to provide fluid flow between an inner portion and an outer portion of the work string.
