DESCRIPTION
Acoustic Attenuation Spectroscope (AAS) as Sound Spectroscope for Drilling Mud With the new redundant Ultrasonic sensors from IBJ technology (www.ibj-technology.com) powerful process-spectroscope can be built up. Beneficial is to use multiple devices to monitor the process of drilling in deepwater drilling. The sound spectroscpe are very helpful in finding oil and gas in deeper formations. Particularly useful is use in pressurized drilling muds. The study of nonlinear vibrations in the sound and ultrasonic range is a very practical and high resolution methods to identify the flow of liquids or gases, preferably hydrocarbons in the well bore in real time during the drilling. The sound pressure is the function to ensure enough also in gas. All muds, regardless of whether oil based or water based lb/gal can be safely monitored with the highest densities of up to about 20 lb / gal on inflow. Furthermore, changes in the turbulence or the profile of the flow can be detected in the pipes immediately. Evaluation of sound velocity is so high resolution, even the smallest tributaries are recognized by gaseous or liquid hydrocarbons. Each process is customizable by the sampling rate and the FFT analysis. With multiple devices along the mud riser an expansion can be detected in a timely manner by gas. The Ultrasonic sensors developed by IBJ technology robust designed for use in the deep sea. Universally, these sensors can be fitted in all types of marine riser or mud lines. The Drilling Mud Spectroscopes can be with all solutions to the early gas kick detection and combine with the inflow control devices. IBJ technology offers its solutions to all interested parties to use.

„Acoustic Attenuation Spectroscopy (AAS) is commonly used to measure particle size distributions (PSD) in the range 5 nm to 100 microns of aqueous, as well as, non-aqueous colloidal samples such as Chemical Mechanical Polishing (CMP) slurries, Ceramic Slips, Printing Inks, Minerals, Catalysts, Metal Oxides, Pigments, Cosmetics, O/W and W/O emulsions, and others.
Commonly measured attenuation levels are in the range of near zero to over 100 dB/cm in the frequency range 1-100 MHz. The percent solids level (discrete-phase concentration) of measured samples is typically in the range 0.1 to 60% volume although Greenwood et. al. have used long-path measurements on lower-concentration samples. „
