Tethys Oil AB (publ)
Tethys Oil is a Swedish energy company focused on identification and
development for production of oil and natural gas assets. Tethys’ core area is
the Sultanate of Oman, where the company is the second largest onshore oil and
gas concession-holder with licence interests in three onshore blocks. Tethys
also has licences onshore France, Lithuania and Sweden. Tethys’ strategy is to
invest in projects in areas with known oil and natural gas discoveries that
have not been properly appraised using modern technology. In this way, high
returns can be achieved with limited risk.
