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 /day will be treated by replacing incumbent chemicals with 3 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 /day 3 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.
