High pressure seal adapter for splitter conductor housing to wellhead connection

1. A high pressure seal adapter for a conductor housing of a wellhead, the high pressure seal adapter having a unitary body comprising:

a first circular bore extending through said unitary body, the first circular bore having a circular perimeter extending beyond a centerline of said unitary body; and

a second circular bore adjacent the first circular bore and extending through said unitary body; wherein

the centerline of said unitary body defines the first circular bore and the second circular bore by positioning the centerline between the first circular bore and the second circular bore; and where in

said seal adapter is configured to be installed in said conductor housing of said wellhead.

2. The high pressure seal adapter of claim 1 , further comprising at least one seal extending around a perimeter of said unitary body, said at least one seal is configured to contact said conductor housing.

3. The high pressure seal adapter of claim 1 , further comprising an upper and lower planar surface, wherein said lower planar surface is configured to rest on a flange of said conductor housing, such that said upper planar surface is substantially co-planar with an upper surface of said conductor housing.

4. The high pressure seal adapter of claim 1 , wherein said seal adapter is configured to be rotated 180 degrees and installed in said conductor housing to facilitate well drilling operations for a second well.

5. The high pressure seal adapter of claim 1 , wherein said seal adapter is configured to operate at well pressures up to 34.5 Mega Pascals.

6. The high pressure seal adapter of claim 1 , wherein the first circular bore comprises a flange extending partially into the first circular bore around an inside surface of the first circular bore.

7. The high pressure seal adapter of claim 6 , wherein the first circular bore is configured to receive a high pressure riser, said high pressure riser having a lower surface that contacts said flange and at least one seal extending around an outside perimeter of said riser, to facilitate well drilling operations through said high pressure riser and said first circular bore for a first well.

8. The high pressure seal adapter of claim 7 , wherein the flange comprises a downward taper.

9. A method of completing a well, the well comprising a wellhead with a conductor having a conductor housing attached thereto, the method comprising the steps of:

providing a high pressure seal adapter having a unitary body comprising:

a first circular bore extending through said unitary body, the first circular bore defining a circular perimeter extending beyond a centerline of said unitary body: and

a second circular bore adjacent said first circular bore and extending through said unitary body; wherein

the centerline of said unitary body defines the first circular bore and the second circular bore by positioning the centerline between the first circular bore and the second circular bore; and where in

installing said seal adapter in said conductor housing of said wellhead.

10. The method of claim 9 , further comprising:

connecting a high pressure riser to said conductor housing, said high pressure riser having a lower surface that extends into said first circular bore and contacts a flange in said first circular bore, and at least one seal extending around an outside perimeter of said high pressure riser, to facilitate well drilling operations through said high pressure riser and said first circular bore for a first well.

11. The method of claim 10 , further comprising the steps of:

removing said high pressure riser;

removing said seal adapter;

rotating said seal adapter 180 degrees;

reinstalling said seal adapter in said conductor housing;

connecting a first casing hanger through said second circular bore to the conductor housing; and

connecting said high pressure riser to said conductor housing, said high pressure riser having a lower surface that extends into said first circular bore and contacts said flange, and at least one seal extending around an outside perimeter of said riser, said at least one seal contacting said side wall to facilitate well drilling operations through said high pressure riser and said first circular bore for a second well.

12. The method of claim 11 , further comprising the steps of:

removing said high pressure riser;

connecting a second casing hanger through said first circular bore to the conductor housing;

installing first and second casings in said first and second wells, respectively;

attaching a first wellhead to said conductor housing above said first well; and

attaching a second wellhead to said conductor housing above said second well.

13. The method of claim 11 , wherein said high pressure drilling and extraction operations are conducted at well pressures up to 34.5 Mega Pascals.

14. The method of claim 10 , wherein said high pressure drilling and extraction operations are conducted at well pressures up to 34.5 Mega Pascals.

15. The method of claim 9 , wherein;

said seal adapter further comprises an upper and lower planar surface; and

said step of installing said seal adapter further comprises seating said lower planar surface on a flange of said conductor housing such that said upper planar surface is substantially co-planar with an upper surface of said conductor housing.
