Expert log analysis finds pay zones in conventional and unconventional plays

One of the most important decisions regarding a new well are where and how to complete it. Getting a fast, accurate and understandable reading on open hole and cased hole logs is critical in this decision.

Log Analysis Solutions, LLC, (LAS) uses a trio of proprietary, real-world programs to analyze logs created by any logging company to help producers understand downhole conditions and to make the right completion choices. LAS’s Nick Maschas and Lee Sanders combine for decades of experience, which they use to deliver this information to their clients.

Payfinder is the proprietary software that takes those endless data lines on a log and creates "Aha!" moments by graphically portraying organic content, water saturation, fractures and mud logs in order to clearly identify pay zones.

RockPro is used to obtain fracture initiation pressure and along with rock strength and brittleness, all essential in developing a good frac design. Maschas says, "A lot of people take this step for granted, using documented equations, but we have put in the long hours doing real world testing and fine tuning our equations."

The third product, FracModel, takes all the data acquired from Payfinder and Rockpro and creates a visual representation of the frac design, helping producers optimize their completion before they actually pump the job. This allows LAS to tailor the amount of stages and perforation points.

All this leads to better placement of stages and optimizing pay while making more oil and saving money. Maschas says, "A real step change for our customer was our ability to produce all of our products using common cased hole logs (CNL/GR). As far as I know we are the only ones doing this. We have been successful doing it for over a year."

"Our models were obtained by analyzing real data in the Permian Basin," Maschas points out, "including full wave sonic and micro imager data, along with sidewall and full bore core samples." LAS continues to refine its models from client input. "We want to know about your results," Maschas continues. "We are successful by helping you be successful."

While many of LAS’s clients are small-to-medium companies, including some startups, they count some of the larger independents and a few publicly traded companies on their list. "Lots of companies that need logging expertise do not have the resources to employ a full time team," says Maschas. "That’s where we come in."

LAS can accept log data by email or through their secure FTP site. When they finish their analysis they generate reports in both hard copy and PDF formats along with a LAS file. The digital files can also be sent by email or FTP, and the hard copies sent by overnight service. Twenty-four hour turnaround is the goal. Maschas and Sanders are available for questions and consultation once the reports are done.
