Drilling locations

From Wikimarcellus

Drilling locations are usually organized into quadrants--that is, rectangular tracts--depending upon geographical layout of the area.

In northeastern Pennsylvania Marcellus shale drilling typically proceeds in a straight line northwest and southeast.

Each quadrant is approximately 1000 feet wide made up of 3 horizontal wells side-by-side separated by approximately 200 feet. Wells may extend horizontally from their pad out roughly 6000 feet in either direction going northwest to southeast. Each quadrant is 1000 feet wide by 12,000 feet long. Quadrants all run side-by-side and end-to-end.
