Abstract

During cementing operations darts and/or cementing plugs are launched from the cement head and pumped into the well. Tattle tales detect the passage of these devices through the cement head giving the operators precise indication of the launched device entering into the work string. Tattle tales are installed on the cement head and are subjected to extreme pressures. Previous mechanical or hybrid (any mechanical, radioactive, acoustical, electrical, magnetic combination) tattle tales have significant operational limitations due to the friction force induced by the internal cement head pressure. The present invention discloses a pressure balanced tattle tale that is unaffected by pressure applied to the tattle tale

Tattle tales detect the passage of these devices through the cement head giving the operators precise indication of the launched device entering into the work string.

Tattle tales are installed on the cement head and are subjected to extreme pressures.

Previous mechanical or hybrid (any mechanical, radioactive, acoustical, electrical, magnetic combination) tattle tales have significant operational limitations due to the friction force induced by the internal cement head pressure.
