"They just don’t build ‘em like they used to.”
There’s something to be said for stuff that’s withstood the test of time. It just works. So we decided not to mess too much with a good thing. Our electromagnetic (EM) MWD system is built around long-time, field proven, reliable systems.
It’s like getting the old man’s truck –then “pimping it out.”
We took that reliable base and improved it. Like our new, patent pending isolation sub. It uses dual isolation to increase the reliability of getting EM signals to surface.

It’s got guts
It’s the only EM MWD system that’s retrievable and reseatable. Simply put, if you’re stuck in the hole, our equipment can be brought out, saving you the cost of replacement.
It’s fast. We get that saving time and money is important. You want to get in and get out. EM technology transmits data to surface four times faster than standard mud pulse, allowing you to drill quickly and economically.
It’s accurate and reliable. Extra care and attention to our operating systems, combined with EM technology, means we’re able to drill with target-hitting precision. With EM, there are no moving parts, reducing the chances for mechanical-related failures.
It’s robust. You need tough equipment to endure the environment downhole. Our EM MWD system has been designed to withstand high vibration and high temperatures. View the technical specs.
It’s efficient. We’ve achieved a significant improvement in battery usage, getting an extended lifespan on our batteries. Mostar’s EM system runs 400 hours on a single battery, compared to 150-hour life spans for standard mud pulse systems. It’s a more efficient use of energy. And it gives you the longer run times you need.
And it’s cost-effective. Batteries are a huge operating expense with MWD. Longer battery life can result in lower operating costs for you.
Last but not least, it’s compatible. With gamma, focused gamma and underbalanced pressure technologies to enable formation monitoring while drilling.
It’s always smart to have a spare
Drilling is risky business. Things happen downhole and you need to react quickly. So we give our clients that extra bit of assurance by sending both mud pulse and EM technology to every well site.
And like you, we can’t stand clutter, so our encoding/decoding method is consistent across both technologies, minimizing excess equipment on site.
