Title: METHODS AND SYSTEMS FOR USING ELASTOCALORIC MATERIALS IN SUBTERRANEAN FORMATIONS
Abstract:
The present disclosure relates to methods and systems for using elastocaloric materials in subterranean formations. A variety of downhole packages, for example, electronic packages and instrumentation packages, are utilized in subterranean formations during hydrocarbon exploration and production operations. Downhole packages are typically designed to operate below a maximum temperature. When a downhole package is placed in the subterranean formation, its temperature may increase as a result of the natural temperature of the subterranean formation in which it is being used. Additionally, many of these downhole packages used downhole generate heat during operation which may raise the temperature of the downhole package. Reaching or exceeding the maximum temperature of a downhole package may result in ineffective operation and/or complete destruction of the downhole package. As a result, the downhole package may need to be frequently replaced. Furthermore, additional steps may be needed to ensure the temperature in the subterranean formation does not exceed the design temperature of the downhole packages and/or to cool downhole packages prior to being introduced into the subterranean formation.
