-- Item 1: maximum number of wells in the model
-- - there are two wells in the problem; injector and producer
-- Item 2: maximum number of grid blocks connected to any one well
-- - must be one as the wells are located at specific grid blocks
-- Item 3: maximum number of groups in the model
-- - we are dealing with only one 'group'
-- Item 4: maximum number of wells in any one group
-- - there must be two wells in a group as there are two wells in total
