Under the first deal with Taqa, Proserv will build a control system for three subsea wells near the Tern platform in the Cladhan field.
The other contract with an unnamed established operator involves subsea well and manifold control systems.
Proserv said the deals strengthened its position in the subsea controls and communications field.
Proserv chief executive David Lamont said: "Both contract wins reflect Proserv's industry-leading position and strong track record for delivering high-value integrated technology systems on time and within budget.
"Proserv's fast-growing suite of technologies have been developed based on the company's 'ingeniously simple' philosophy and are underpinned by the company's international talent pool of technical and engineering expertise which has expanded considerably through organic growth and strategic acquisition."
Westhill-based Proserv specialises in exploration and production, drilling and infrastructure technical solutions and services to the energy industry.
The company operates worldwide from 30 sites in six geographical regions.

Adams will make her professional debut in Manchester on Saturday when she fights Argentina's Virginia Carcamo.
"Virgil has a lot of knowledge and one thing I like about him is he knows how to take an Olympic champion and turn them into a pro," said Adams, 34.
"He did it with Andre [Ward] and he's capable of doing the same with me."
American Ward, 33, has gone from winning gold at the 2004 Olympics to becoming a two-weight world champion and being unbeaten in 31 fights.
Adams has been training alongside the likes of IBF, WBA and WBO light-heavyweight champion Ward as she prepares for her fight, and says doing so "has left me a bit in awe, to be honest".
She added: "Like every fighter, my ultimate goal is to headline a show in Las Vegas and with the way the sport is building at the moment I see no reason why I can't get there.
"Other female boxers like Claressa Shields and Katie Taylor have been putting women's professional boxing on the map and now that I've joined them it can only raise the bar again."

The Scottish champions went out 4-3 on aggregate after a 2-0 defeat in Sweden.
Deila said: "The hype about the Champions League is big, everybody wants it so badly. You have to deal with it but we looked very stressed.
"We didn't look like we wanted to go out and play football. We have a lot of young players coming through but this was a hard lesson for us."
The Norwegian was new to the Celtic manager's job when his team was knocked out in the play-off round last season by Slovenian side Maribor.
But having reshaped the team on his way to winning the Scottish Premiership in his debut season and across this summer, he was confident he could guide them into the group stage of the Champions League at the expense of the Swedish champions.
And with a 3-2 lead heading to Malmo's 20,000 capacity stadium his side were in a strong position to qualify.
Malmo are fifth in the Swedish league, seven points off the leaders with only nine matches to play of their summer season.

But Celtic will now compete in the Europa League and find out their opponents in Friday's group stage draw. Among the teams in Europe's second-tier competition are Liverpool and Tottenham.
"We looked very uncomfortable on the ball. We looked frightened and scared and that is very disappointing," he said in his media conference afterwards.
"It was a team performance that was not at the level we should expect at these games. We have to learn from this, some very hard learning.
"We knew if we were at our best we had a good chance to go through but we were not even close.
"We have shown that the Europa League is the level we have to compete at and it is better than nothing. It is a good competition."
Asked about the goal Nir Bitton had disallowed for a foul - replays showing that Bitton's marker, Kari Arnason, had handled the ball in the aerial challenge - Deila felt Serbian referee Milorad Mazic had made "a big mistake".
"It could have changed the game - it is irritating that we lost that," he said.
