This article is intended to briefly describe the well configurations and philosophy of some meritorious air injection projects that have employed horizontal wells. Vertical injector-horizontal producer and horizontal injector-horizontal producer combinations have both been implemented.
An important observation with the use of horizontal wells is the potential difficulty in controlling the air injection or production profile along the lateral. Apart from being highly dependent on the geological framework, restrictions in the lateral can exacerbate any such issues.
We intend to update this page as information on other noteworthy projects becomes available.
