Abstract
A method is described for determining well integrity including deploying seismic sensors in a wellbore; attaching a vibrational source to well hardware; using the vibrational source to generate seismic signal that moves through the wellbore; creating a seismic dataset by recording the seismic signal at the seismic sensors; and processing the seismic dataset to make a processed seismic image. The processed seismic image may be displayed on a graphical display in order to identify well integrity problems such as wellbore deformation, well casing damage, or problems with cement.
Claims8
A computer-implemented method of determining well integrity, comprising:
- a. deploying seismic sensors in a wellbore;
- b. attaching a vibrational source to an exterior or interior section of well hardware;
- c. using the vibrational source to generate seismic signal that moves through the wellbore;
- d. creating a seismic dataset by recording the seismic signal at the seismic sensors;
- e. processing the seismic dataset to make a processed seismic image;
- f. generating a graphical representation of the processed seismic image;
- and
- g. displaying the graphical representation on a graphical display.
