## Abstract

A jetting tool includes a tubular housing having: couplings formed at each longitudinal end thereof, and one or more ports formed through a wall thereof and in fluid communication with an upper portion of a bore of the housing. The jetting tool further includes a valve mechanism isolating the housing bore upper portion from a lower portion thereof in a closed position and operable to an open position where the valve mechanism provides fluid communication between the housing bore portions.

## Claims

### Claim 1

A jetting tool, comprising:
a tubular housing having:
couplings formed at each longitudinal end thereof, and
one or more ports formed through a wall thereof and in fluid communication with an upper portion of a bore of the housing; and
a valve mechanism isolating the housing bore upper portion from a lower portion thereof in a closed position and operable to an open position where the valve mechanism provides fluid communication between the housing bore portions.

### Claim 2 (depends on 1)

The jetting tool of claim 1, wherein the housing ports include one or more upwardly inclined ports, one or more radial ports, and one or more downwardly inclined ports.

### Claim 3 (depends on 1)

The jetting tool of claim 1, wherein:
the valve mechanism comprises a piston disposed in the housing bore, and
the piston has:
a sleeve,
a solid nose, and
one or more ports formed through a wall of the piston sleeve and in fluid communication with the housing bore upper portion.

### Claim 4 (depends on 3)

The jetting tool of claim 3, wherein the piston ports are downwardly inclined.

### Claim 5 (depends on 3)

The jetting tool of claim 3, wherein:
the housing further has a seal receptacle formed in an inner surface of the housing, and
the valve mechanism further comprises seals straddling the piston ports and engaged with the seal receptacle in the closed position.

### Claim 6 (depends on 3)

The jetting tool of claim 3, wherein:
the valve mechanism further comprises a fastener restraining the piston in the closed position, and
the fastener is operable to release the piston in response to fluid pressure in the housing bore upper portion exceeding a threshold pressure.

### Claim 7 (depends on 6)

The jetting tool of claim 6, wherein:
the piston is downwardly movable relative to the housing once released by the fastener,
the jetting sub further comprises a stop connected to the housing and operable to prevent upward movement of the piston in the closed position, thereby bidirectionally closing the valve mechanism.

### Claim 8 (depends on 6)

The jetting tool of claim 6, wherein the fastener is a shear ring.

### Claim 9 (depends on 1)

A running assembly for deploying a bearing assembly to a receiver, comprising:
the jetting tool of claim 1; and
a running tool for carrying the bearing assembly and connected to the jetting tool.

### Claim 10 (depends on 1)

A method for washing an interior of a component, comprising:
deploying the jetting tool of claim 1 to the component using a tubular string; and
pumping wash fluid down the tubular string to the jetting tool, wherein the housing ports impinge the washing fluid against the interior of the component.

### Claim 11

A method for deploying a bearing assembly to a receiver, comprising:
deploying a running assembly to the receiver, the running assembly comprising: the bearing assembly, a running tool carrying the bearing assembly, and a jetting tool connected to the running tool;
washing an inner surface of the receiver using the jetting tool;
latching the bearing assembly to the washed inner surface of the receiver; and
releasing the bearing assembly from the running tool.

### Claim 12 (depends on 11)

The method of claim 11, wherein:
the running assembly is deployed by assembling the tools as part of a tubular string, and
a bottom of the tubular string is disposed in a wellbore while the tools are assembled as part thereof.

### Claim 13 (depends on 12)

The method of claim 12, further comprising:
monitoring an exposed formation adjacent to the wellbore for instability; and
shifting the jetting tool to a well control mode in response to detection of the instability.

### Claim 14 (depends on 13)

The method of claim 13, wherein:
the inner surface is washed by pumping wash fluid down the tubular string to the jetting tool using a wash pump, and
the jetting tool is shifted by pumping a second fluid down the tubular string to the jetting tool using a mud pump.

### Claim 15 (depends on 13)

The method of claim 13, wherein the formation is monitored by:
measuring a flow rate of the injected fluid;
measuring a flow rate of returning fluid; and
comparing the flow rates.

### Claim 16 (depends on 12)

The method of claim 12, wherein:
the tubular string is a drill string, and
the tools are assembled as part of a drill string while a drill bit thereof is disposed in a wellbore.

### Claim 17 (depends on 16)

The method of claim 16, further comprising drilling the wellbore after releasing the bearing assembly by rotating the drill bit while injecting drilling fluid through the drill string and lowering the drill string.

### Claim 18 (depends on 11)

The method of claim 11, wherein the receiver is part of an upper marine riser package.

### Claim 19 (depends on 11)

The method of claim 11, further comprising:
connecting the jetting tool and the running tool;
stabbing the connected tools into the bearing assembly; and
latching the bearing assembly to the running tool;
