john, I don't see any advantage for drilling more than one lateral in your example.  The added cost would not be recouped until some undetermined time in the future.  If an operating company had long term plans to produce two different vertically separated zones from the same vertical wellbore they would likely drill and complete the deeper interval, HA in your example, and, once the well reached a point of depletion, plug and abandon the lower portion of the vertical hole, mill a window in the casing at the desired shallower interval depth and drill a lateral targeting that zone.  If there is no desire to attempt a dual completion (produce both intervals simultaneously) I would see no benefit in drilling both laterals during the same operation.  I do think there may be dual lateral HA wells in E TX but that is different from what I think you are asking and beyond my knowledge to comment upon further.

 There are no dual laterals in HA where two intervals are produced from the same vertical string. There are a number of "stacked lateral" completions but each lateral has it's own surface hole and vertical string. The wells are very close together and share the same allocated acreage and profile but the laterals are stacked in different intervals (HA, BO). The production is reported under only one lease ID as if it came from one well.
