Fit-for-purpose rig

From Wikimarcellus

Fit-for-purpose (FFP) rigs have a streamlined design optimized for drilling multiple wellbores using a single well pad. This is called pad drilling. It reduces the impact on the environment as much as possible, because multiple-wells from a single pad can target larger areas underlying environmentally delicate surface areas. Generally, pad drilling can be done with a much smaller surface footprint.

FFP rigs typically are very high-performance with large-capacity mud pumps, computerized drilling control systems, and are very mobile. They have lighter, more powerful top drives with higher torque and greater efficiency, automated pipe-handling capability for efficiency and crew safety, AC drawworks that for greater horsepower applied to the drill bit, and built-in measurement and control systems to support decision-making and analysis.
