ENERGIX-Stort program energi

Cryogenic cooling canister for downhole tools

Alternative title: CryoCan

Awarded: NOK 5.5 mill.

Project Number:

282266

Project Period:

2018 - 2022

Funding received from:

Location:

This project will develop and demonstrate technology that will revolutionize downhole logging and intervention operations in high temperature geothermal wells. Logging is performed in all the phases of a wells life and it is an important contribution to reducing the drilling and exploration risk, improving reservoir characterization and optimizing production and maintenance. The high well temperatures and a limited selection of high-temperature electronics imposes several limitations on existing wireline tools such as: - Reliability issues when pushing the electronics towards their maximum temperature ratings. - High cost electronics. - Reduced sensing accuracy due to severe temperature variations during operation. - Short downhole operating time. - Large and heavy logging instruments. Norwegian Well owns a patented CryoFlask cooling technology that targets these limitations and enables a new generation of tools with higher temperature ratings, improved reliability and lower cost to performance ratio. The proposal targets the "Tema 2: Fornybar energi - Geotermisk: Å utvikle norsk kompetanse og teknologi for et internasjonalt marked med vekt på å overføre kunnskap og teknologi fra andre sektorer" theme by developing the CryoFlask technology for deep geothermal applications. The consortium partners represent both the geothermal industry and the O&G industry enabling cross-fertilization between the two industries.
