MVW signs Green De-Oiler Technology Trial Agreement with a Major O&G Producer in the Sultanate of Oman

Bergen, Norway, June 5, 2025 -- M Vest Water (EURONEXT: MVW) announces that a
major Oil & Gas producer in Oman has decided to qualify NORWAFLOC®. The
qualification will take place at the oil field, which is the largest Produced
Water contributor in Oman.

The large-scale trial will be conducted over a two-week period in Q3 2025.
During this trial, a Produced Water stream of 110,000 m[3]/day will be treated
by replacing incumbent chemicals with our patented, nature-based NORWAFLOC®
de-oiler and demulsifier. Upon meeting the operator's treatment success
criteria, MVW's environmentally friendly NORWAFLOC® chemical may be qualified
for use in this major oilfield and within the operator's Produced Water
activities in general.

The field where the trial takes place has a total Produced Water production of
240,000 m[3]/day and is a reputed flagship in sustainable Produced Water
management. Approximately half of this Produced Water is used to build the
largest constructed wetland in the world, where the cultivation of vegetation
results in the greening of the desert and the creation of new habitats for
birds, fish and wildlife. At the same time, the natural vegetation filters and
cleans the Produced Water. This sustainable method of handling the Produced
Water developed in this oilfield has garnered multiple awards and headlines
around the world.

"We are very pleased that the client has chosen to qualify MVW's products at
this prestigious oil field, and thereby giving MVW the opportunity to add
value to this sustainable showpiece our client has created within Produced
Water management. With our nature-based NORWAFLOC®, we believe we can
contribute to this customers' high sustainability goals and achieve
substantially increased oil reclamation, and implicit revenue gains, in the
oil-water separation before it goes to the wetland treatment," says Tor Olav
Gabrielsen, Executive Chairman at MVW.
