Devon Energy Drills 36 Wells from a Multi-well Barnett Shale Pad

by Kenneth E. DuBose on August 17, 2011

Devon Energy multi-well pads are becoming more common across the Barnett Shale in North Texas. The company recently completed 36 wells from a single 12 acre drilling pad. The use of pads has many benefits with one being less surface disturbance. That means more land that can be used for other purposes, fewer private roads that need to be built, and less overall traffic than the area would have experienced with 36 well pads versus one. The trend of more multi-well pads is being made easier by horizontal drilling technology. With Devon stepping up to the plate, expect pressure to rise in other areas where this approach has yet to be implemented.

Placing several wells on one site reduces the company’s impact on developable land. This is especially important in populated areas. Well pads generally are similar in size whether they contain one wellhead or a half-dozen, so placing multiple wells on the same pad can dramatically minimize surface disturbance.

This process further reduces surface disturbance by eliminating the need for additional lease roads. This, in turn, decreases the company’s road construction costs.

Multi-well pads are far more efficient, because once a well is drilled, the rig moves only 20 feet or so to drill the next one. This also reduces truck traffic, which benefits our neighbors.

In rural areas, Devon can be more flexible about where to drill. This gives landowners more input on both the placement of tand the construction of the roads.

Within an incorporated area, a multi-well pad reduces the uncertainty involved with the permit process. Most cities and towns require a permit for each new well. If five wells are to be placed on the same pad, the chances are greater that each of those five permits will be approved

Devon can more efficiently produce natural gas from a chosen reservoir by drilling horizontally in close proximity

Devon often can reduce the number of storage tanks and liquid separators by consolidating the operations onto one pad. This further decreases the company’s surface disturbance while reducing operating expenses.

Multi-well pads allow Devon’s lease operators to better manage the wells assigned to them while cutting their driving time.

The results of multi-well pads are most clearly evident in the Barnett Shale area of north Texas, where Devon is the largest producer. One existing pad contains 11 wells. Most recently, Devon placed 36 wells on one pad and 21 on another.
