In the Eagle Ford, denser development means that in the future the number of child wells is likely to exceed the number of higher-producing parent wells.

Maintaining production in the shale business is getting increasingly costly because new wells in major US shale plays are falling short of output from the parent wells.

A study of 10 major US basins by Schlumberger (SPE 189875) found that while the parent and child wells looked comparable at first glance—about half of new wells outperform the older wells and vice a versa—the picture changes when the results are adjusted for the higher cost of drilling and fracturing new wells.

This is a pressing issue in the shale sector where constant drilling is required to replace short-lived older wells, which is leading to increasingly dense development.
