The forecast is an attempt to look into the future. In the O&G Industry they do not have crystal balls. Instead they collect historical data from which they attempt to calculate reasonable forecasts into the future.That's a 'forecast' and has more to do with maintaining the illusion of scarcity than actual production and availability levels.
Considering the time that has past since that 2012 forecast, I'd say it is doing a reasonably good job. Current production data support that,

So mid 2019 forecast in the graph I provided is not way off. Hence, their decline rate forecast was not bad but then such is the behavior of a non-renewable resource (within humanities life span). They decline, something that they are well aware of in this industry.

These pumping jacks are not installed to create a scarcity and hide production. Producers are there attempting to maximize profit and minimize cost in order to get the most from their investment. Thus they use them because the flow rates are so low that this is the most economical way to extract what is left underground.
Here we can see pumping jacks in Bahrain which wouldn't shock anyone familiar with the industry there.
