Systems, spacer devices and methods for aligning multi-well modular templates and associated wells

A multi-well modular drilling template spacer device to space and angularly align at least one multi-well modular drilling template of a plurality of multi-well modular drilling templates or one or more wells associated therewith in relation to at least one other multi-well modular drilling template of the plurality of multi-well modular templates or one or more wells associated therewith, the multi-well modular drilling template spacer device comprising:

• a main body having a bore sized to slidably receive and connect to outer surface portions of a low-pressure housing of a second well extending through one of a plurality of well funnels of a multi-well modular template connected to a housing of a first well;
• a guide funnel having a bore sized to slidably receive a low-pressure housing of a third well, the guide funnel comprising an at least approximately cylindrical portion and a centering ring portion connected to an upper end of the at least approximately cylindrical portion, the centering ring portion having a substantially frustroconical shape to thereby guide the low-pressure housing of the third well in alignment with a central axis of the guide funnel during operational insertion thereof;
• and
• an elongate spacing arm connected to and extending between the main body and the guide funnel.

A subsea multi-well drilling template system, the system comprising:

• a first multi-well modular template of a plurality of multi-well modular templates, the first multi-well modular template comprising a plurality of well funnels connected to form a unitary template structure, a first one of the plurality of well funnels having a bore sized to slidably land about and circumscribe a low-pressure housing of a first well, a second one of the plurality of well funnels positioned along a perimeter of the unitary template structure and having a bore sized to slidably receive and circumscribe a low-pressure housing of a second well;
• a spacer device configured to space and angularly align at least one well of a second multi-well modular template of the plurality of multi-well modular templates in relation to at least one well of the first multi-well modular template, and to space and angularly align the second multi-well modular template in relation to the first multi-well modular template, the spacer device comprising a main body having a bore sized to slidably receive and connect to outer surface portions of the low-pressure housing of the second well, a guide funnel having a bore sized to slidably receive a low-pressure housing of a third well, and an elongate spacing arm connected to and extending between the main body and the guide funnel;
• and
• a second multi-well modular template comprising a plurality of well funnels connected to form a unitary template structure, a first one of the plurality of well funnels having a bore sized to land about and circumscribe the low-pressure housing of the third well after removal of the spacer device.

A method of spacing and angularly aligning multiple multi-well modular drilling templates or one or more wells associated therewith, the method comprising the steps of:

• providing a multi-well modular drilling template spacer device comprising a main body having a bore sized to slidably receive and connect to outer surface portions of a low-pressure housing of a second well extending through one of a plurality of well funnels of a multi-well modular template connected to a low-pressure housing of a first well, a guide funnel having a bore sized to slidably receive a low-pressure housing of a third well, and an elongate spacing arm connected to and extending between the main body and the guide funnel;
• angularly orienting the spacer device when connecting the spacer device to the low-pressure housing of the second well so that the position of the guide funnel identifies a proper spacing and alignment of the third well;
• extending drilling equipment through the bore of the guide funnel to drill a wellbore of the third well;
• and
• extending the low-pressure housing of the third well through the bore of the guide funnel to position the low-pressure housing of the third well in the wellbore of the third well.
