Schematic templates — every well type

one renderer, one barrier model · drawn from register data (strings, survey, cement tops, packers, junctions) · not to scale
Illustrative values — placeholder method bands; no signed method profile (Gate B)

Vertical

straight producer · platform & land example: B-04
surface 800 m perfs 2,150 m shoe 2,300 m
Single borehole: surface and production casing, cement sheath and perfs are drawn from the tallies. A-annulus (tubing × production casing) and B-annulus (production × surface casing) are assessed; C is cemented to surface and not monitored.

Deviated (J-profile)

kick-off point from the deviation survey example: L-21
reservoirKOP 620 m MDTD 2,900 m MD · 50°
Strings follow the trajectory as concentric curves computed from the survey (MD/TVD); the kick-off point and doglegs come from the register revision.

Horizontal (L-profile)

reservoir lateral · see well A-05 1 data assumption

Build curve and lateral come from the survey; the casing shoe, screens and packer from the completion register. Missing inputs (here the B-annulus fluid top) render as flagged amber gaps.

Multilateral

dual lateral from one parent junctions are master data
zone Azone Bjunction @ 1,850 m MDL1L2
Each borehole carries its own strings and barrier envelope. Junction metadata is master data; how annuli behave across a junction is defined by the method spec — junction assessment is out of MVP scope.
