Drill-through spool body sleeve assembly

A sleeve assembly for a drill-through spool body having a bore having a wall, the assembly comprising:

• a wear bushing removably installed in the bore;
• a test sleeve removably installed within the bore and within the wear bushing;
• and
• at least a portion of the outer diameter of the test sleeve sealingly engaging the bore wall.

A sleeve assembly for a drill-through spool body having a bore having a wall, the assembly comprising:

• a wear bushing removably installed in the bore;
• a test sleeve removably installed within the bore and within the wear bushing;
• and
• both the test sleeve terminal ends extending past the terminal ends of the wear bushing and sealingly engaging the bore wall.

A sleeve assembly for a drill-through spool body having a bore having a wall, the assembly comprising:

• a wear bushing removably installed in the bore;
• a test sleeve removably installed within the bore and within the wear bushing;
• and
• the terminal ends of the wear bushing sealingly engaging the bore wall and the terminal ends of the test sleeve sealingly engaging the wear bushing.

A method of pressure testing a drill-through spool body comprising:

• removably installing a wear bushing in a bore with a wall in the spool body;
• removably installing a test sleeve within the bore and within the wear bushing and with the test sleeve terminal ends sealingly engaging the bore wall to prevent pressure from passing between the inside of the test sleeve and spool body ports, outlets, and valves;
• and
• pressure testing the spool body ports, outlets, and valves.

A method of drilling a well bore using a drill-through spool body comprising a bore having a wall, outlets, ports, and valves, the method comprising:

• removably installing a wear bushing in the bore with the outside of the wear bushing contacting the bore wall;
• removably installing a test sleeve within the bore and within the wear bushing with the test sleeve terminal ends sealingly engaging the bore wall to prevent pressure from passing between the inside of the test sleeve and spool body ports, outlets, and valves;
• connecting the spool body to a wellhead housing;
• pressure testing the spool body outlets, ports, and valves;
• removing the test sleeve from the spool body without removing the wear bushing;
• and
• protecting the bore wall and the outlets, ports, and valves during the drilling of the well bore with the wear bushing.

A method of pressure testing a drill-through spool body comprising:

• removably installing a wear bushing in a bore with a wall in the spool body;
• removably installing a test sleeve within the bore and within the wear bushing with a first test sleeve terminal end sealingly engaging the bore wall, a first terminal end of the wear bushing sealingly engaging the bore wall, and a second terminal end of the test sleeve sealingly engaging the wear bushing first terminal end to prevent pressure from passing between the inside of the test sleeve and spool body ports, outlets, and valves;
• and
• pressure testing the spool body ports, outlets, and valves.

A method of drilling a well bore using a drill-through spool body comprising a bore having a wall, outlets, ports, and valves, the method comprising:

A method of testing a drill-through spool body having transverse bores and a vertical through bore with a wall, the method comprising:

• covering at least one of the transverse bores with a first member;
• sealing at least one of the transverse bores with a second member by sealing with the through bore wall;
• and
• pressure testing the transverse bores.
