6 FAQs about [Rigs needed to drill all shale proved reserves]

How do Shale well drilling rigs work?

For shale well drilling specialized drilling rigs are required to handle long and heavy drill strings in order to drill thousands of feet into the ground vertically and then thousands more feet horizontally.

What drilling rigs are used in shale development?

The drilling rigs used in shale development are usually "top-drive" rigs that are capable of "walking" short distances (on the order of 20 feet) in order to drill multiple wells on one well pad without the need to dis-assemble and re-assemble the rig between each well.

Do you need a drilling rig in Pennsylvania?

Most producing companies do not own or maintain their own drilling rigs and must lease rigs from a drilling or service company. For shale gas drilling in Pennsylvania, heavy duty rigs are required to handle long (heavy) drillstrings for deep drilling.
