Hybrid Completions

Tartan Provides Reliable and Efficient Completion of the Deepest Stages in Hybrid Extended Reach Horizontals


In most North American oil and gas plays, the exploitation trend is to drill longer horizontal wells and stimulate with more stages. Completion methods requiring coiled tubing operations, such as cemented sleeves and plug-and-perf, are unable to effectively stimulate stages closer to the toe due to the target depths. As a result, many operators are looking for a more efficient and reliable completion technology to complete the deepest, most challenging zones of their extended-reach horizontals.


Tartan’s patented MultiFrac™ limited entry and EnerFrac™ single entry ball-drop systems can be run in hybrid completions to enable effective stimulation of toe stages – from the first two to the first mile.

The sleeves feature patent-pending BurstPoint™ ports that keep the system internals completely closed during installation and the cementing process. This eliminates the risk of cement invasion, mitigating issues during stimulation operations.

Additionally, these systems are designed with torque-through threads to facilitate installation and improve cementing operations via rotation and reciprocation (see table).

The MultiFrac and EnerFrac hydro-mechanical sleeves are activated with standard or dissolvable balls and enable stimulation of clusters or individual stages, respectively. Once shifted by an actuation ball, liner pressure is increased to fully open the BurstPoint ports to achieve communication with the formation.


Tartan MultiFrac and EnerFrac systems have been successfully run as hybrid completions in a variety of plays throughout North America (see run history). These systems enable higher rate treatments than coiled tubing methods – particularly at the toe – resulting in an enhanced fracture network and increased production.
