The 23-year-old has made 18 appearances and Head Coach Richard Hill firmly believes he has a bright future in the game and at Sixways.
"I'm over the moon to sign the new deal," said Porter. "I have really enjoyed my time at Warriors so far. It was a big step up for me from Plymouth Albion and I've relished that challenge.
"The set-up is second-to-none with all the backroom staff, physios and conditioners. It just makes your job easier as you can focus purely on the rugby and your performance.
"Over the course of the two years I feel I have learnt a lot. Phil Vickery has been a big influence this season and John Andress has also been really helpful with looking at my game and how I can improve.
He added: "The signings we have made, plus the fact that a lot of the boys have re-signed, is all positive and we feel we will have an even stronger squad next season.
"Players like Josh Matavesi has have in and made a big impact and I'm sure the new guys will come in and do that too.
"On a personal level, I'm recovering from a shoulder injury so I'm just looking to get that right and back out playing as soon as possible."
