Currently, well capacity ramp up is modeled by a randomized n week increase trend followed by a parallel indefinite decline. With the addition of oil reservoirs, we are going to tie output to reserves such that output is proportional to available oil. However, this alone doesn't provide a means for output to ever increase as reservoirs will only deplete.

To address this, as well as to provide an interesting new bit of strategic complexity to the game, wells will be assigned a pumping capacity index. New wells will have a capacity of 1. Capacity can increase as time goes by. Capacity combined with the reserves will determine actual well output.

This design will give us a much more accurate way to simulate peak oil. We should see Hubbart's curve on both individual oil reservoirs and the field as whole as capacity increases and reserves decline.

Initially, we will provide an approximation of what we have today with an n week capacity increase. This will typically provide the well ramp up players are accustomed to. Declining reserves will eventually win, with output dropping regardless of what capacity is doing.

In a future release, well capacity can be put under the control of the player under the following rules.

• Initial well capacity is 1. Capacity can not be changed the first week a well is operational.
• Capacity can be increased by 1 by building out well infrastructure at a cost equal to the initial drill cost. Capacity for a given well can only be increased once per week.
• Capacity can be decreased by selling off well infrastructure. For each unit of capacity sold, the player recovers half of the cost of that infrastructure (half the initial drill cost).

In the UI this functionality can be made available on the weekly report screen with key binding for increasing and decreasing capacity (left and right arrows?) We will likely need a new CAPACITY column, so we'd have to break with the classic formatting on this screen a bit.
