ENSURE CASING INSTALLS TO TD IN EXTENDED REACH WELLS
Advancements in drilling technology has allowed operators to drill wells with ever increasing horizontal lengths, which can create concerns landing casing at planned total depth (TD). Interra Energy’s Black Phantom® Floatation Sub was designed to ensure casing will reach desired TD.
During casing installation, the Black Phantom helps reduce overall torque and drag through a proprietary activation mechanism that utilizes a glass disk to keep the section beneath the tool filled with air. With the air chamber intact throughout the horizontal section, friction is reduced allowing for the string to be floated into the well.

Installation
The Black Phantom can be installed anywhere in the casing string based on client requirements.
Activation
After successfully running casing to TD, pressure is increased to the pre-calculated shear value, shattering the disk and enabling circulation. Upon activation, only small pieces of glass are produced, ensuring all downhole equipment is unaffected, eliminating the need for a debris sub.
