The drilling process begins with padsite construction, which typically lasts approximately two weeks, depending on the location. Next, the setup of the rig and the drilling of the well take approximately three to five weeks per well. During this time, operations run continuously 24 hours a day, seven days a week.
Multiple wells are sometimes drilled from a single padsite. Although the rig is the most visible part of drilling operations, it is temporary and will be removed once drilling is completed. Once the layer of rock that holds the natural gas (pay zone) is reached, the well will be completed and prepared for production. Even with multiple-well padsites, the entire process frequently takes less time than the building of a house or store in the same area.
Drilling practices are designed to have the smallest possible impact on the environment. Operators must work with communities to determine truck routes and implement security measures.
As with any construction site, there will be additional truck traffic for the setting up and taking down of the equipment. There can be noise, dust and traffic. Like any typical construction project, however, Chesapeake makes it a priority to minimize these disturbances. The majority of residents will experience few, if any, changes to daily life.
After the wells are completed, the company regularly returns to monitor and maintain the site. At some wellsites, trucks may return to remove naturally occurring water (produced water), which is separated from natural gas during the production process and stored in on-site tanks.
