Inflow Control Devices - Pending Patent

MARKKLEEBERG, Germany - Oct. 17, 2014 - PRLog -- The devices generally refer to the monitoring of drilling in search of oil or gas in deeper formations, which are under pressure. In more detail regarding this safety equipment and methods to identify the flow of liquids and / or gases, preferably hydrocarbons in the wellbore in real-time during drilling operations.
With new high performance ultrasonic sensors all drilling fluids can be measured with i the dissolved and free gases.
The sound pressure is sufficient to guarantee the function also in gases. All muds, whether oil based or water based can be safely monitored with the highest densities of up to about 20 lb / gal on inflow.
Solids can not interfere with the measurements.
The evaluation of the sound velocities as high resolution, the smallest inflows are recognized by gaseous or liquid hydrocarbons.
Interference of the signals by the rotating drill string can not be detected.
The functions of the inflow control device was tested under dynamic shear stress at different Mud.
In addition to monitoring the sound velocities, the measurement of the flow rate of the mud.
Use multiple units along the mud riser expansion of gas can be detected in time.
Developed by IBJ Technology Ultrasonic sensors are robustly constructed for use in the deep sea. Universally, these sensors can be installed in all types of marine riser or mud lines
