Abstract
A device, system and method to process acoustic images of tubulars and wellbores. Corrections for real-world logging are calculated and stored in correction Look Up Tables (LUT), which are used to display projections or create geometric models of the wellbore or tubular. The user interface allows the user to interact with the projections to update the LUTs to operate on the images. This process helps correct for real-world challenges such as tool eccentricity, tool rotation, tool angle, and speed of sound differences in order to create a more intuitive rendering.
Claims20
A method of processing acoustic images from an acoustic imaging device comprising:
- receiving the acoustic images of tubulars,
- determining plural logging correction values for plural locations of the tubulars;
- rendering one or more projections of the tubulars for a user display by:
- identifying display pixels required in display space;
- identifying image pixels in the acoustic images corresponding to each display pixel using a) a coordinate transformation from acoustic image space to display space and b) the plural logging correction values;
- then blending the identified image pixels to create the display pixels;
- and
- displaying the one or more projections on the user display.
A system for processing acoustic images of a tubular, the system comprising a user interface, one or more computing devices configured to:
- receive acoustic images of tubulars;
- determine plural logging correction values for plural locations of the tubular;
- render one or more projections of the tubular for a user interface by:
- i. identifying display pixels required in display space;
- ii. identifying image pixels in the acoustic images corresponding to each display pixel using a) a coordinate transformation from acoustic image space to display space and b) the plural logging correction values;
- iii. blending the identified image pixels to create the display pixels;
- then
- display the one or more projections on the user interface.
