1. A system for conveying fluid into a wellbore, comprising:
- a tubular member disposed in the wellbore through a first zone, a second zone, and a hydrocarbon producing zone of the wellbore;
a packer disposed adjacent to the tubular member in the wellbore, wherein the packer is configured to at least partially isolate the hydrocarbon producing zone from at least one of the first and second zones;
a hydrodynamic flow device disposed around the tubular member at a position between the packer and a surface location, the hydrodynamic flow device comprising a pump fluidly connected to a discharge in fluid communication with the first zone and an inlet in fluid communication with the second zone;
a seal device disposed around the hydrodynamic flow device to isolate a first annulus of the first zone from a second annulus of the second zone; and
a monitor and control system by which the hydrodynamic flow device is controlled to adjust flow of fluid therethrough in a manner which maintains pressure in the hydrocarbon producing zone below hydrostatic pressure in the wellbore.

Abstract
A system for conveying fluid into a wellbore, including a tubular member, a packer, a hydrodynamic flow device, and a seal device. The tubular member is disposed in the wellbore through a first zone, a second zone, and a hydrocarbon producing zone of the wellbore. The packer is disposed adjacent to the tubular member, and is configured to at least partially isolate the hydrocarbon producing zone from at least one of the first and second zones. The hydrodynamic flow device is disposed around the tubular member and comprises a pump fluidly connected to a discharge in fluid communication with the first zone and an inlet in fluid communication with the second zone. The seal device is disposed around the hydrodynamic flow device to isolate a first annulus of the first zone from a second annulus of the second zone.

6. An apparatus for controlling pressure in a wellbore, comprising:
-
a tubular member disposed in the wellbore through a first zone, a second zone, and a hydrocarbon producing zone of the wellbore and in fluid communication with a source of a proppant; a hydrodynamic flow device disposed in the wellbore and around the tubular member and comprising a pump having a discharge in fluid communication with the first zone and an inlet in fluid communication with the second zone; a service tool disposed on the tubular member, distal the hydrodynamic flow device, having a flow port defined therein in fluid communication with an annulus defined between the tubular member and the wellbore; a wash pipe adjacent the service tool, wherein the wash pipe has an inner diameter in fluid communication with the flow port; a filter media disposed about the wash pipe, wherein the inner diameter of the wash pipe is in fluid communication with an exterior of the filter media such that a liquid flowing radially inwardly through the filter media enters a distal end of the wash pipe and flows longitudinally through the wash pipe until exiting into the annulus through the flow port; and a control and monitoring system controlling the hydrodynamic flow device to regulate pressure in the hydrocarbon producing zone from a position outside the hydrocarbon producing zone. - View Dependent Claims (7, 8, 9, 10)
