Buaben joined Partick on loan from Carlisle on transfer deadline day in search of regular first-team football and he made his debut in last weekend's draw with former club Dundee United.
The 25-year-old joined Carlisle in October after his summer release from Watford, but he found himself in and out of the side at Brunton Park.
Buaben missed out on the 2010 World Cup due to injury and he admits the reason behind his decision to join Partick Thistle was to try and gatecrash the Ghana squad for this summer's World Cup finals
"I spoke to my agent and the Ghana manager Akwasi Appiah and he told me that I needed to be playing regularly if I wanted to have a chance of going to the World Cup and that is why I have come to Partick Thistle," Buaben told Sky Sports.
"I want to play as often as I can and try to impress the Ghana manager so that he takes me to Brazil."
Buaben admits missing the 2010 finals in South Africa was a major blow for him and that it would be a dream come true to play for Ghana at a World Cup.
"I was unlucky that I missed the last World Cup with Ghana because of injury and I am determined not to experience that disappointment again.
"It is a dream for any player to represent their country at a World Cup and I hope I can realise that dream."
Buaben insists he is not thinking about his long-term future at Carlisle with his contract due to expire in the summer and is focused on doing his best to help Partick Thistle secure survival in the Scottish Premiership.
"I have not thought about my future at Carlisle," added Buaben. "I have come to Partick Thistle to play games and help my new team-mates stay up.
"From what I have seen so far I think we have a good squad and have enough ability to stay up and hopefully I can do my part.
"I want to focus on Partick Thistle until the end of the season and then we will see what happens in the summer."
