The biggest asset of most oil and gas companies is their leasehold: the contracts or deeds that give the company the right to either drill wells and produce oil and gas on someone else's land, or give them title to that land outright. A typical oil and gas company is involved in thousands of these uniquely negotiated leases, and the software to keep these documents organized hasn't been updated in more than a decade, says James Yockey, founder of Houston-based Landdox.

Landdox does just that: provides an organizational framework for companies' contracts and leaseholds. The company recently entered into an integration with Houston-based ThoughtTrace, an artificial intelligence program that can scan and pull out key words and provisions from cumbersome, complicated contracts and leaseholds.

With this integration, companies can use ThoughtTrace to easily identify key provisions of their contracts, and then sync up those provisions with their Landdox account. From there, Landdox will organize those provisions into easy-to-use tools like calendars, reminders and more.

The framework behind the integration
The concept behind Landdox isn't entirely new — there are other software platforms built to organize oil and gas company's assets — but it's the first company in this space that's completely cloud-based, Yockey says.

"Within these oil and gas leases and other contracts are really sticky provisions … if you don't understand them, and you're not managing them, it can cause you to forfeit a huge part of your asset base," Yockey says. "It can be a seven-, eight-, or nine-digit loss."

These contracts and leases can be as long as 70 or 80 pages, Yockey says, and have tricky provisions buried in them. Before the integration with ThoughtTrace, oil and gas companies would still have to manually pour over these contracts and identify key provisions that could then be sent over to Landdox, which would organize the data and documents in an easy-to-use platform. The ThoughtTrace integration removes a time-consuming aspect of the process for oil and gas companies.

"[ThoughtTrace] identifies the most needle moving provisions and obligations and terms that get embedded in these contracts by mineral owners," Yockey says. "It's a real source of leverage for the oil and gas companies. You can feed ThoughtTrace the PDF of the lease and their software will show you were these provisions are buried."

The origin story
Landdox was founded in 2015, and is backed by a small group of angel investors. Yockey says the investors provided a "little backing," and added that Landdox is a "very capital-efficient" software company.

Landdox and ThoughtTrace connected in 2017, when the companies were working with a large, private oil and gas company in Austin. The Austin-based oil and gas company opted to use Landdox and ThoughtTrace in parallel, which inspired the two companies to develop an integrated prototype.

"We built a prototype, but it was clear that there was a bigger opportunity to make this even easier," Yockey says. "To quote the CEO of ThoughtTrace, he called [the integration] an 'easy button.'"

The future of ERP software
Landdox's average customer is a private equity-backed E&P or mineral fund, Yockey says, thought the company also works with closely held, family-owned companies. Recently, though, Landdox has been adding a new kind of company to its client base.

"What's interesting is we're starting to add a new customer persona," Yockey says. "The bigger companies – the publicly traded oil and gas companies –have all kinds of different ERP (Enterprise Resource Planning) software running their business, but leave a lot to be desired in terms of what their team really needs."

At a recent North American Prospect Expo summit, Yockey says that half a dozen large capitalization oil and gas producers invited Landdox to their offices, to discuss potentially supplementing the company's ERP software.

"Instead of trying to be all things to all people, we stay in our lane, but find cool ways to connect with other software (companies)," Yockey says.
