ImageTrak High-Resolution Ultrasonic Borehole Imaging Service
Images mean more
The ImageTrak™ high-resolution ultrasonic borehole imaging service enables detailed evaluation of formation fractures, features, and borehole geometry in any type of borehole fluid, including oil-based mud.
Poor borehole quality and/or stability are issues that stem from various root causes; inherent formation characteristics, a poorly designed or matched drilling fluid and/or mechanical problems due to BHA vibration. The result is poor performance, poor annular cleaning, lost circulation and stuck pipe that can cost millions of dollars. The ImageTrak ultrasonic transducers measure both amplitude and travel time, generating a 256-sector image of the wellbore. The amplitude image represents acoustic impedance contrasts of the borehole wall to identify and evaluate variations of lithology, bedding, lamination or physical rock features. The ImageTrak service provides the visibility to reduce NPT and lower the risk of losing a BHA in the hole when drilling difficult wells with geomechanical challenges.
In unconventional applications, fractures are the key to the productivity of the well. During drilling, the wellbore will have natural fractures as well as induced fractures and they can be open or closed. The ImageTrak service travel-time image displays the oriented borehole shape and size, which is indicative of the distance of the transducer to the wellbore wall. This is advantageous for identifying open, closed, and mineralized fractures. The ImageTrak service provides high quality images that will facilitate an optimum completion design to maximize hydrocarbon production and minimize water production.
The ImageTrak service operates in both oil and water-based drilling mud systems with a wide range of mud weights. The system's high sampling rate and three transducers support penetration rates up to 400 ft/hr and can correct for wellbore eccentricity effects.
The ImageTrak service compliments any formation evaluation service by providing high quality wellbore images to enable better decisions and deliver better wells.
