The Mostar Difference
It’s happened to you before. You’re having trouble with your vehicle, so you take it to the mechanic’s shop. Expecting it to be a small thing, they surprise you with an enormous bill. You don’t have parts to justify the damages; much less a detailed explanation of what went wrong. “That’s very similar to what happens across the directional industry.” (JP).
Mostar is about a new way of doing business. “Imagine a service station that invites you to come over and take a look at what’s wrong with your vehicle. They take things apart in front of you, put new parts in, and then start it up. You get to see them take care of it. You get a bill for fair value. And your vehicle works. Wouldn’t you be more satisfied? That’s what we do here.” (JP)
At Mostar, we feel that’s how it should be done.

Complete Quality Control
There’s a lot at risk out in the field. That’s why we don’t rely on third party definitions of good maintenance. From development and manufacturing to planning, inspection and trucking - it all happens at Mostar.
Real Facilities
Our in-house, full-service, oilfield machine and full fabrication shop gives us the capability to manufacture and service our own tools, from start to finish. This helps ensure real quality and reliability in the field.
True Preventative Maintenance
Failures result from trying to “get another run” out of a tool that needs servicing. Whether a motor has been downhole for five minutes or 150 hours, each time our motors return from the field they’re pulled apart, fully inspected and serviced.
Our internal tracking systems also allow us to record in-depth histories on each of our tools. “We can tell what we put into that motor, how many hours were logged on each piece and any maintenance or measurements, all the way through to cost.” (RP) After all, our clients need to know we’ve done our due diligence.
Costs Up Front
Our clients know ahead of time what their directional project will cost them. We don’t believe in hidden costs or surprise bills. Mostar is a cost-controlled environment, which enables our customers to control capital costs and expenses and budget accordingly.
A Single Invoice
Clients get just one bill for our entire service package, including directional services and MWD, manufacturing, equipment servicing, inspection and trucking.
Solid Commitment to R&D
Mostar’s in-house research and development team is always working to improve our capabilities in equipment performance through development of innovative tools, equipment and processes for the directional drilling industry.
In-House Inspection
Certified inspectors verify that our equipment is ready to go out to the rig. Mostar’s staff are ASNT (American Society for Nondestructive Testing) accredited and do a complete inspection of all equipment. We’re very thorough when it comes to maintaining our quality.
