Quantum Energy Partners, which backs oil drilling companies such as HG Energy, has raised its seventh private equity fund at around $5.8 billion. Quantum is a Houston-based energy-focused private equity firm. The firm was founded in 1998 by S. Wil VanLoh Jr. and Toby Neugebauer. Neugebauer and VanLoh are former investment bankers at Kidder, Peabody & Co. The two co-founded energy-focused investment bank Windrock Capital. Neugebauer's father is Randy Neugebauer,(R-Texas), a former member of the U.S. House of Representatives. “The energy sector remains an attractive place for private capital to play an outsized role," says Quantum president Dheeraj Verma. "As the energy landscape continues to evolve globally, it is presenting us with many opportunities to create entrepreneurially driven businesses that can create jobs and value in a safe and responsible manner. We are excited about the next decade of energy growth and activity, particularly as North America will play a larger role in providing the world with low-cost and responsible energy." Some of Quantum's other investments include Ceritas Energy, Crump Energy Partners, EnergyQuest and Intensity Midstream.

For the moment, Elon Musk is struggling to overcome his doubters. Less than 24 hours after stunning Wall Street by tweeting that he might take Tesla Inc. (Nasdaq: TSLA) private, six of the company’s directors confirmed that he’d indeed raised the possibility with the board. Musk owns an almost 20 percent stake in Tesla, meaning he’d still need roughly $70 billion in financing to take Tesla private. That kind of money may be accessible through sovereign wealth funds or other strategic investors, said Dwight Scott, president of Blackstone Group LP’s (NYSE: BX) GSO Capital Partners. Musk’s money-losing and cash-burning company is an unlikely candidate for debt investors to be willing to help go private, reports Bloomberg News. Many questions remain unanswered, including the big one: how would Tesla come up with the money to pull off a deal valuing the unprofitable company at more than $80 billion?
