However, present solutions to feed theses sensors are expensive and dangerous and there is so far no technology able to generate electrical energy in the operational conditions of oil and gas extraction wells. In this paper it is presented, for the first time in a relevant environment, a pioneering energy harvesting technology based on nanomaterials that takes advantage of fluid movement in oil extraction wells. A device was tested to power monitoring systems with locally harvested energy in harsh conditions environment (pressures up to 50 bar and temperatures of 50\u00baC). Even though this technology is in an early development stage this work opens a wide range of possible applications in deep underwater environments and in Oil and Gas extraction wells where continuous flow conditions are present.<\/jats:p>","DOI":"10.2118\/204877-ms","type":"proceedings-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T00:17:51Z","timestamp":1639527471000},"source":"Crossref","is-referenced-by-count":1,"title":["Energy Harvesting Under Harsh Conditions for the Oil &amp; Gas Upstream Industry"],"prefix":"10.2118","author":[{"given":"Jos\u00e9","family":"Correia","sequence":"additional","affiliation":[{"name":"inanoEnergy"}]},{"given":"C\u00e1tia","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"IFIMUP and Faculty of Sciences of University of Porto"}]},{"given":"Ricardo","family":"Esteves","sequence":"additional","affiliation":[{"name":"inanoEnergy"}]},{"given":"Ricardo Cesar","family":"Bezerra de Melo","sequence":"additional","affiliation":[{"name":"Repsol E&P"}]},{"given":"Jos\u00e9","family":"Guti\u00e9rrez","sequence":"additional","affiliation":[{"name":"Repsol Technology Lab"}]},{"given":"Andr\u00e9","family":"Pereira","sequence":"additional","affiliation":[{"name":"IFIMUP and Faculty of Sciences of University of Porto"}]},{"given":"Jo\u00e3o","family":"Ventura","sequence":"additional","affiliation":[{"name":"IFIMUP and Faculty of Sciences of University of Porto"}]}],"member":"861","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"2024111221363369600_R1","article-title":"DOWNHOLE POWER GENERATION SYSTEM","author":"a.","year":"2018","journal-title":"Patent US 10072480 B2,"},{"author":"a.","journal-title":"Patent US 10472934 B2","article-title":"Downhole Transducer Assembly","key":"2024111221363369600_R2"},{"author":"a.","journal-title":"Patent US 8033328 B2","article-title":"Downhole Electric Power Generator","key":"2024111221363369600_R3"},{"key":"2024111221363369600_R4","article-title":"DOWNHOLE APPARATUS FOR GENERATING ELECTRICAL POWER IN A WELL","author":"a.","year":"1998","journal-title":"Patent US005839508A,"},{"key":"2024111221363369600_R5","article-title":"APPARATUS FOR POWER GENERATION","author":"a.","year":"2014","journal-title":"Patent WO 2014\/118503 Al,"},{"key":"2024111221363369600_R6","article-title":"TURBINE","author":"a.","year":"2017","journal-title":"Patent US 2017 \/ 0284219 A1,"},{"year":"2016","author":"a.","article-title":"2140.
