Abstract
A device and method used to inspect wellbores, cased or uncased using cameras and a phased array ultrasound transducer. The optical and ultrasound images are stored on the device and then registered and analyzed together. The present device overcomes the deficiencies currently experience by downhole camera operators, such as poor scale and lack of volumetric perspective.
Claims20
A downhole imaging system comprising:
- a) an imaging device having:
- illumination;
- a phased array ultrasound sensor;
- and
- an optical imaging sensor,
- wherein the ultrasound and optical imaging sensor are arranged to focus laterally outward from the housing;
- b) one or more memories for storing images from the phased array ultrasound sensor and the optical imaging sensor;
- and
- c) a computer processor and computer instructions for co-registering the images from the optical and phased array ultrasound sensors.
6 more elements
A method for imaging a wellbore comprising:
- imaging said wellbore using an optical imagine sensor and illumination;
- imaging said wellbore using a phased array ultrasound sensor;
- receiving and storing optical images and ultrasound images;
- co-registering the optical images with the ultrasound images;
- and
- rendering a 3D visualization of said wellbore using the co-registered optical images and ultrasound images.
