Abstract

A downhole bypass tool that includes an inlet for receiving fluid into a housing of the bypass tool is described herein. The bypass tool also includes a flow directing apparatus disposed in the housing for directing fluid to flow into an operational flow path of a vibratory tool. The vibratory tool is at least partially disposed within the hosing of the bypass tool. The flow directing apparatus operates to selectively bypass the operational flow path of the vibratory tool such that the fluid bypasses the operational flow path of the vibratory tool and flows out of an outlet of the bypass tool.

Claims (17)

1. A method, the method comprising:

running a bottom hole assembly (BHA) into a well, the bottom hole assembly including a vibratory tool disposed above a perforator in the BHA and a bypass tool disposed above the vibratory tool wherein the fluid pumped to the operational flow path of the vibratory tool to operate the vibratory tool flows through the bypass tool;

an inlet for receiving fluid into a housing of the downhole tool; and

a flow directing apparatus disposed in the housing, the flow directing apparatus having a first position and a second position, the flow directing apparatus in the first position directs fluid to flow into an operational flow path of a vibratory tool at least partially disposed within the housing of the downhole tool to operate the vibratory tool and the flow directing apparatus in the second position causes the fluid to bypass the operational flow path of the vibratory tool; the flow directing apparatus comprises:

a body securely disposed within the downhole tool, the downhole tool having a first passageway in fluid communication with the inlet and the operational flow path of the vibratory tool and a second passageway that diverts fluid away from the operational flow path of the vibratory tool; and

a sleeve slidably and rotatably disposed in the first passageway of the body, the sleeve has a first position where fluid is permitted to pass through the passageway in the sleeve to pass to the operational flow path of the vibratory tool and a second position where fluid is blocked from the passing through the passageway and the fluid is diverted to the second passageway of the body;

pumping fluid to an operational flow path of the vibratory tool to operate the vibratory tool; and

pumping abrasive fluid through the operational flow path of the vibratory tool to the perforator to create perforations in the well.

2. The method of claim 1 wherein the flow directing apparatus further comprises;

a first and second depression area disposed on an outside portion of the sleeve, the first depression area extends a predetermined length of the sleeve and extends around the outside portion of the sleeve, the second depression area extending substantially longitudinal on the sleeve;

a first guiding element securely disposed within the body for engaging the first depression area of the sleeve and forcing the rotation of the body as the sleeve is forced downward in the body;

a second guiding element rotatably disposed in the housing for engaging the second depression area of the sleeve to allow for rotation of the second guiding element as the sleeve is rotated as it is forced downward toward the second position, the second guiding element having at least one port that prevents fluid from flowing into the second passageway in the body when the sleeve is in the first position and in alignment with the second passageway of the body when the sleeve is in the second position.

3. The method of claim 1 wherein the sleeve further includes a seat for receiving a fluid blocking member to prevent fluid from flowing through the passageway of the sleeve and forces the sleeve from the first position to the second position.

4. The method of claim 1 wherein the second passageway is in fluid communication with the inlet of the downhole tool and with an annulus area between the vibratory tool and the housing of the downhole tool.

5. The method of claim 1 wherein the second passageway is in fluid communication with the inlet of the downhole tool and with a throughway disposed in a portion of the vibratory tool.

6. The method of claim 1 wherein the second passageway is comprised of multiple passageways.

7. The method of claim 1 wherein the throughway in the body is comprised of multiple throughways.
