Abstract: A method for identifying fluid migration or inflow associated with a wellbore tubular, comprises measuring strain of the wellbore tubular with a system comprising at least one string of interconnected sensors that is arranged such that the sensors are distributed along a length and the circumference of the wellbore tubular; establishing a baseline that is a function of steady state strain measurements within a first time period; and identifying fluid migration or inflow where strain measurements substantially deviate from the baseline within a second time period.

Abstract: Systems and methods for monitoring a well are configured to identify or analyze various issues affecting the well including corrosion, cement quality, inflow, and fluid migration.

Abstract: A method for analyzing fluid proximate an injection well, comprises turning an injector of fluid into the well on or off; determining temperature along a casing of the well during a first time period; and associating a rate of temperature change during the first time period with a fluid.

Abstract: A string of interconnected strain sensors applied to a cylindrical object for monitoring deformation of the object. The string of interconnected strain sensors is applied in a selected zig-zag pattern. A possibility is to drape a pliable support structure around the object, to which the the string of strain sensors has been mechanically coupled in the selected zig-zag pattern.

Abstract: A process may include providing heat from one or more heaters to at least a portion of a subsurface formation. Heat may transfer from one or more heaters to a part of a formation. In some embodiments, heat from the one or more heat sources may pyrolyze at least some hydrocarbons in a part of a subsurface formation. Hydrocarbons and/or other products may be produced from a subsurface formation. Certain embodiments describe apparatus, methods, and/or processes used in treating a subsurface or hydrocarbon containing formation.
