Drilling and Well Operation

Once the well pad has been constructed it's time mobilize the drilling rig and assemble it on the well pad to allow well drilling operations to begin. Most energy companies do not own or maintain their own drilling rigs and therefore they lease rigs from a drilling service company. In fact, energy companies generally outsource the majority of the specialty services they need to develop oil and gas, everything from the seismic work, well site development, drilling, and fracturing, but they do provide technical direction, project management and the money to fund the operation. 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. These rigs may cost $50,000/day or more to lease, along with the costs of drilling the well with a crew and materials such as casing and cement. A typical well in the Marcellus shale may cost $3-5 million to drill and construct, along with another $3-5 million to hydraulically fracture, so a well may cost between $6-10 million dollars to develop before any oil or gas can be produced, on top of all the upfront exploration, leasing, and well pad construction work.
