Initial Start: MWD/LWD Manufacturers and Suppliers List

Updates on October 28, 2009:
For a complete and updated list, please visit this page.


It is generally known in the oil and gas industry that the big oilfield service companies like Schlumberger, Halliburton, Baker Hughes and Weatherford are manufacturing their drilling tools by themselves, including MWD/LWD tools. They also conduct their own research and development to find best methods in producing and running the tools. The competition among them is so frightening. So much so, that they won’t allow others to possess their tools by any means.

So now comes a question,

“If I want to start a new (independent) Directional Drilling/MWD/LWD service company, where can I purchase MWD/LWD tools and its spare parts if the big guys won’t allow me to do that ?”

This was the main reason which triggered me to list MWD/LWD manufactures and suppliers in this world. To help people like you who want to start a business in this industry.

As far as I know, there were three independent MWD/LWD manufacturers. Now becomes two, as one had been acquired by the other one two years ago. They are not so well known like the big guys, but have been active in this business for such a long time. Their tools are affordable, robust, reliable and their support is also second to none.

Who are these guys?

1. General Electric Oilfield Technology (GE OFT)

This company has involved in the oilfield industry for more than 30 years now. They are manufacturing many oilfield equipment used by leading operators and service companies in the world. At the beginning they only provide the well known positive pulse Tensor MWD system, but due to their acquisition of Sondex few years ago, they now have the negative and electromagnetics MWD systems. Besides MWD tools, GE also provides LWD systems, like Gamma Ray and Resistivity tools. How about the price? That all depends on your requirements, whether you need for directional only, directional + gamma, or directional + gamma + resistivity. Just contact one of their representatives nearby you for more information about the price and the support.

More information about GE and its products can be found here.

2. Kambi Enterprises Inc.

Kambi, as stated on their website, is a MWD services dedicated company, located in Calgary, Alberta, Canada. They design and manufacture their own tools based on GE Tensor design and technology. They have a variety of MWD systems arranging from positive pulse (PP), continous wave electromagnetic (CW-EM) to PP/CW-EM combination. They also invented Rotary Flow Switch (RFS) to extend the battery life for longer running hours. Good news is some of these tools can work together or are fully compatible to GE Tensor tools and existing Landing Muleshoe Subs. For LWD system, they only provide Gamma Ray. How about the price? Once again, it is based on what you need for your project. Just an indication for you, their prices are bit lower than GE prices.

More information about Kambi and its products can be found here.

Actually I have heard some other companies which also do the same business as above, but I haven’t time to confirm it yet one by one. So, if you think you know companies where you can purchase the MWD/LWD tools, please let me know. I will add your information here.

In addition to this, I also would like to invite MWD/LWD suppliers out there to provide their information. Tools or systems without spare parts are impossible, right? We surely need to repair our tools someday and do maintenance by replacing some parts with the new ones. So, I guess by adding the suppliers information here would have added values to all of us. Do you agree with me, guys? 🙂

FYI, you don’t have to pay me to get listed. It’s free. I am doing this just for fun and hope it would be an useful resource for all visitors of this blog. It is my pleasure to see your business is running well and profitable. Perhaps we could work together someday.

Please stay tuned. This list is going to be expanded soon with more details.

Thank you!
