Prior to their success at Kingsholm the Sixways outfit had won just one fixture in the game's shorter format but standout performances from several players saw them progress.
And 23-year-old De Carpentier believes it was his side's determination in defence and ability to get on the scoreboard early that not only underlined their performances but also will prove hard to beat at The Rec this Friday.
"From the past history of the J.P. Morgan Premiership Rugby 7s Worcester had not done very well and we had maybe won just the one game before Thursday night," said De Carpentier.
"But we trained well in the week and we all thought we would do well and it turned out we did alright on night, winning all our games.
"We had a look back at it and we were all pretty happy with the way that we defended in most games and the way we came out of the blocks and started scoring tries early doors.
"Once you gain the momentum in 7s it is hard to get it back and we were happy with the attitude of the players chasing back, chasing lost causes and pushing guys out wide.
"Those extra two points can make a lot of difference at the end of a game as 7s is a game of fine margins and whenever we can we look to get those marginal games.
"The boys working back shows the ethos of the squad at the moment as well. Working hard for each other and that all adds up."
Worcester have the privilege of opening up the night's entertainment with a clash against Aviva Premiership champions Leicester Tigers - De Carpentier's former side.
And the young forward insists despite Leicester's lack of success in the J.P. Morgan Premiership Rugby 7s, they won't be taking them lightly as they look to get off to a good start.
"It will be great to start things off, hopefully they can pack The Rec out and it should be an exciting night," he added.
"I get on with a lot of the boys at Leicester well and it will be good to see a few friendly faces again.
"They didn't have a great history in the tournament either as they usually take a lot of younger lads but we will see what team they bring on Friday and hopefully we can both be competitive."
