Wellbore fluid treatment process and installation
First Claim
1. A wellbore installation in a wellbore liner including an inner diameter, a first perforated interval and a second perforated interval positioned uphole from the first perforated interval, the wellbore installation comprising:
- a first tubular member installed over the first perforated interval in the inner diameter of the wellbore liner, the tubular member including an open upper end adjacent an upper limit of the first perforated interval, an open lower end adjacent a lower limit of the perforated interval, a wall extending from the open upper end to the open lower end and a port through the wall;
a first closure for the port installed in the first tubular member and actuable between a closed position closing the port and an open position wherein the port is open; and
a sealing element settable to create a seal between the tubular member and the wellbore liner in a position between the open upper end and the first perforated interval and between the open lower end and the first perforated interval; and
a second tubular member installed over the second perforated interval in the inner diameter of the wellbore liner, the second tubular member being separate from the first tubular member and including an open uphole end adjacent an upper limit of the second perforated interval, an open downhole end adjacent a lower limit of the perforated interval, a wall extending from the open uphole end to the open downhole end and a port through the wall;
a closure for the port installed in the second tubular member and actuable between a closed position closing the port and an open position wherein the port is open; and
a sealing element settable to create a seal between the tubular member and the wellbore liner in a position between the open uphole end and the second perforated interval and between the open downhole end and the second perforated interval, the second tubular member spaced from the first tubular member and the closure of the second tubular member being actuable separately from the closure of the first tubular member.

Abstract
A method for isolating a perforated interval of a well, the well including a casing liner having a wall with a plurality of perforations therethrough forming the perforated interval, the method comprising: providing a tool including a tubular body including an inner diameter and an outer surface, a first open end and a second open end, the first and second open ends providing access to the inner diameter; and a sealing element to isolate a mid region of the outer surface from the first open end and the second open end; positioning the tool in the well with the tubular first open end adjacent and above an uppermost perforation of the perforated interval and the second open end adjacent and below a lowermost perforation of the perforated interval; and installing the tool in the well with the sealing element sealing between the tubular body and the casing wall above the uppermost perforation of the perforated interval and below the lowermost perforation of the perforated interval to isolate fluid flow between the perforations and the inner diameter.

7. A method for isolating a perforated interval of a well, the well including a casing liner having a wall with a plurality of perforations therethrough forming the perforated interval, the method comprising:
-
providing a tool including a tubular body including an inner diameter and an outer surface, a first open end and a second open end, the first and second open ends providing access to the inner diameter; and
a sealing element to isolate a mid region of the outer surface from the first open end and the second open end;positioning the tool in the well with the tubular first open end adjacent and above an uppermost perforation of the perforated interval and the second open end adjacent and below a lowermost perforation of the perforated interval; and installing the tool in the well with the sealing element sealing between the tubular body and the casing wall above the uppermost perforation of the perforated interval and below the lowermost perforation of the perforated interval to isolate fluid flow between the perforations and the inner diameter; positioning a second tool in the well to cover a second perforated interval in the well, the second tool being separate from the tool and including a tubular body defining an inner diameter and an outer surface, an uphole open end and a downhole open end, the uphole open end and the downhole open end providing access to the inner diameter; and
a sealing element to isolate a mid region of the outer surface from the uphole open end and the downhole open end;
installing the second tool in the well with the sealing element sealing between the tubular body and the casing wall above and below the second perforated interval to isolate fluid flow from the inner diameter to the second perforated interval;opening access through the tool to the perforated interval; and treating the well through the perforated interval while the second perforated interval remains isolated to fluid flow. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
