Abstract
Some implementations include a system comprising an electrical line positioned proximate to one or more subsurface formations; and a permanent downhole sensor array coupled to the electrical line, the permanent downhole sensor array including one or more downhole sensors, each downhole sensor including: a first sensing device configured to detect at least a first component of a downhole fluid.
Claims20
A system comprising:
- an electrical line positioned in a wellbore proximate to one or more subsurface formations;
- and
- a permanent downhole sensor array coupled to the electrical line and positioned, at least in part, within a cemented portion of the wellbore, the permanent downhole sensor array including one or more downhole sensors disposed inside set cement of the cemented portion of the wellbore, each downhole sensor including:
- a first spectral sensing device configured to detect at least a first component of a downhole fluid in the set cement.
1 more element
An apparatus comprising:
- a downhole sensor to be disposed inside set cement within a cemented portion of a wellbore proximate to one or more subsurface formations;
- and
- a first spectral sensing device housed within the downhole sensor, the first spectral sensing device configured to identify at least a first component of a downhole fluid in the set cement.
A method comprising:
- positioning a permanent downhole sensor array including a first spectral sensing device within a wellbore formed in one or more subsurface formations, wherein the permanent downhole sensor array and the first spectral sensing device are to be embedded inside set cement within a cemented portion of the wellbore;
- and
- configuring the first spectral sensing device to detect a first component of a downhole fluid inside the set cement.
