Projected Products

These products can all be scheduled into the future as rate/time projections. The projections can be forecasted on the graph using Arps, SEDM, other types of decline curves; or the future monthly volumes can be directly inputted as a scheduled projection.

•Gas (Major Phase) - This is the only product that is required to have a projection so that the case runs by default.
