Set? Good. 🙌 🗣 "At first, I thought transitioning to the GreaseBook would've been tough. We'd done things a certain way for a really long time. But, so far the Greasebooks have been very easy to transfer to. I haven’t had any complaints from the pumpers. I really like how the app makes the pumpers be accountable for the oil. I cant tell you how many times their old gauge sheets would have gauges that were so messed up and then throw a run ticket in there -- it was a nightmare to sort out! With GreaseBook, it makes my guys correct any errors. Thanks for everything!" 👉 Dustin Wyer, Operations | Val Energy | Wichita, KS 🏢🛢 🗣 "Upon beginning, I wasn't sure whether the GreaseBook Oil & Gas Production Software would give us the flexibility we needed with our reporting. However, over the last year, GreaseBook has given me the ability to take on a considerable amount of supervision of the company. Now, I don’t have to rely so heavily on our contract field supervisor. In fact, I compared this year's overhead with that of last year's, and we have been able to reduce our costs by more than half. And, those reduced costs include our this year's GreaseBook charges! Thanks for developing this tool!!" 👉 Susie Agee, Vice President | Marsh Oil & Gas Co. | Pauls Valley, OK 🏢🛢 🗣"I was VERY hesitant to try the GreaseBook software at first. That said, once we got ahold of it I saw just how much time it was going to save us. GreaseBook’s oil sales report with run ticket images alone saves us 3-4 days a month. In fact, we know what our purchaser owes us (and what they’re missing) even before they’ve sent us our statement... Now that they know we're watching our account so closely, we find even less mistakes on their part because they know we’re holding them accountable!" 👉 Bobi Posey, Admin | Phoenix Oil & Gas, Inc | Seminole, OK 🏢🛢 🏆 Oil & Gas Awards Finalist for New Tech Development of the Year 📰 As featured in the American Oil & Gas Reporter 📰 As featured in E&P Magazine 📰 As featured in the Oil & Gas Financial Journal 📰 As featured in SPE's 'The Way Ahead' BE THE OFFICE HERO, STREAMLINE YOUR OPERATIONS, AND DISCOVER WHY SOME OF THE INDUSTRY’S MOST EFFECTIVE OPERATORS RELY ON GREASEBOOK OIL & GAS PRODUCTION SOFTWARE TO DO THEIR BEST WORK 💪🏼 ✅ Focus: From orphan wells to lengthy routes, no matter what form your pumping takes, GreaseBook keeps your pumpers focused on moving those production updates from field to office. ✅ Gather: Easily gather everything that matters.
