NS Canada | Most drilling rigs operate on big diesel gensets, as they are in new/ remote areas. If the grid is close by, they may tie in. Windmills wouldn't be used to power the rigs specifically - but some oil companies put windfarms up to offset their energy portfolio. And in other cases windfarms just happen to be out in remote areas where the oil is as well, but they would still be feeding the grid. Oil rigs move around a lot.
Once wells are completed you need to get that oil to surface/market - In some cases they flow under their own pressure and other times there is a need for a pump to assist the products to come to surface (pump jacks. downhole pumps..etc) . Additional power is also needed sometimes for security lighting and the separation and processing equipment. etc
When this is needed, the most usual source is electrical power from the grid. It is the cheapest and least maintenance, but not always available for remote wells. The cost of running wires to the nearest grid may be too high, And in that case engines can be used. Sometimes depending on the products being produced it can be used to directly power engines without further refining. I'm sure there may be some scattered solar and small wind turbines used for some of these remote locations, but that's a different thing than powering an oil rig.
In addition to all that if there are many wells in the area, they would be tied into pipelines, however if they are scattered wells they use holding tanks and the product is picked up by truck, like a milk run. | |
