Abstract
A method of servicing a wellbore, comprising placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in at least a portion of a sealant composition, placing the sealant composition in an annular space formed between a casing and the wellbore wall, and monitoring, via the MEMS sensors, the sealant composition and/or the annular space for a presence of gas, water, or both. A method of servicing a wellbore, comprising placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in a wellbore composition, placing the wellbore composition in the wellbore, and monitoring, via the MEMS sensors, the wellbore and/or the surrounding formation for movement.
Claims29
A method of servicing a wellbore, comprising:
- placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in at least a portion of a sealant composition;
- placing the sealant composition in an annular space formed between a casing and the wellbore wall;
- and
- monitoring, via the MEMS sensors, the sealant composition and/or the annular space for a presence of gas, water, or both.
A method of servicing a wellbore, comprising:
- placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in a wellbore composition;
- placing the wellbore composition in the wellbore;
- and
- monitoring, via the MEMS sensors, the wellbore and/or the surrounding formation for movement, wherein the MEMS sensors are in a sealant composition placed within an annular casing space in the wellbore and wherein the movement comprises a relative movement between the sealant composition and the adjacent casing and/or wellbore wall.
A method of servicing a wellbore, comprising:
- placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in a wellbore composition;
- placing the wellbore composition in the wellbore;
- and
- monitoring, via the MEMS sensors, the wellbore and/or the surrounding formation for movement, wherein at least a portion of the wellbore composition comprising the MEMS flows into the surrounding formation and wherein the movement comprises a movement in the formation.
