Who are we?

Founded in 2011, Sensorfield was started by Strode Pennebaker, a third-generation engineer and fourth-generation oilman. Headquartered in Houston, Sensorfield provides advanced remote oilfield monitoring solutions for wells that previously couldn’t justify any remote monitoring technology.

Sensorfield offers the industry’s only solution designed to monitor equipment and activities throughout the oilfield and installed completely by the user. Capabilities range from simple tank level measurements, and pressure and rate measurements, to state-of-the-art beam pump surface card monitoring and intelligent step-pressure acquisition for near real-time reservoir and well PBU and step-rate analysis.

Featuring small sensors that are affordable, reliable and easy to self-install, our plug & play monitoring system is designed to work right out of the box, with any component able to be swapped out in seconds. The result is valuable data, displayed on a smartphone or PC, that can help you understand and react correctly and quickly to real-world field conditions.

“We’re excited to bring the first simple, high-quality, low-cost monitoring system to the oil patch”

Why did we do it?

Because we wanted a simple, practical system to keep up with wells we've operated ourselves. Something we could install and maintain ourselves with minimum bother.

We started with a basic goal: create a sensor the size of a refrigerator magnet, stick it onto a tank or pipe or anything else, and watch data show up on a PC or cellphone. This was a radical idea at the time — now it’s called the Internet of Things. And we’re the first to bring it to the oil patch.

Why hasn't it been done before?

Probably because nobody wanted to start over from scratch. We began by studying all of the commercial off-the-shelf sensors, radios and SCADA gear we could find. We quickly realized that we needed to redesign the entire system from the ground floor — otherwise we weren't going to make our gear any more affordable than the next guy. And this certainly wouldn’t address the heart of the oil patch: the stripper well population.

So we started over and decided to custom-design and manufacture everything. We had our first system working in less than three months. But it took four more years to perfect the size, ruggedness and quality. Along the way we discovered a groundbreaking new RF technology from Semtech called LoRa™ and became the first company to write fully optimized software for it. We created new sensor designs and found novel ways to imbed high-resolution microsensors into rugged oilfield equipment. Then we optimized everything to run on micropower from tiny solar panels less than 1-½ inches across.
