The Drilling-Technologies MWD Centralizer (Fully Retrievable) Fin
The Drilling-Technologies MWD Centralizer Fin is a fully retrievable and reseat-able design (retrievable / reseat-able through 2.25” – 3.5” I.D. Collars). Being made of a High Density Polyurethane, our Fin offers maximum resistance to down-hole wear and wash making this Fin the ideal choice for a high flow and high solids environment. In addition, High Density Polyurethane maintains its elastic memory, ensuring the highest range of vibration dampening possible.

*** Failure to cut Fin to suggested O.D. will likely result in the Fin being torn from its shaft.
*** Life of the Drilling-Technologies Fin will vary on drilling conditions. We recommend replacing fins when wear becomes visibly noticeable or unacceptable. Fins should be visually inspected periodically; especially when run in invert based mud systems.
