WHO WE ARE
G&H began as a tool and die shop in 1958 with a handful of employees. We manufactured a variety of precision-stamped specialty products used by operators and service companies to drill and complete oil and gas wells.
On a wellsite, our products were only a small part of a complex system of equipment and procedures, but the quality of these products mattered greatly. A product that was improperly manufactured, structurally flawed, or not delivered on time could undermine safety or cause downtime and operating costs to soar. Uncompromising quality has always been essential. Through determined effort, both G&H and our products developed a reputation for dependability.
By 2010, we were experiencing remarkable growth in demand for perforating guns built to the highest level of quality and delivered faster than any of our competitors. In 2011, G&H launched its own patented line of perforating guns under the trade name Yellow Jacket Oil Tools™. A few years later, G&H launched the industry’s most reliable line of patented frac plugs, under the trade name M1™. Following our belief in change for the better, we set course to become the industry’s “Plug & Perf Powerhouse™.”
Today, G&H employs over 300 people. We have 230,000 sq ft of manufacturing space between our ISO 9001:2015 certified manufacturing facilities in Northwest Houston. Manufacturing in Houston provides abundant access to an experienced labor pool and competitive pricing on raw materials. It is our strategic advantage over our competitors. We have earned 52 U.S. patents (awarded and pending).
With over six decades of accumulated knowledge, innovative research and development in materials and processes, and state-of-the-art production and inspection equipment, our craftsmanship and capabilities are unmatched.
We are truly a powerhouse, but one intent on living up to our motto,
“ALWAYS BUILDING, ALWAYS BETTER.”

G&H began as a tool and die shop in 1958 with a handful of employees. On a wellsite, our products were only a small part of a complex system of equipment and procedures, but the quality of these products mattered greatly. A product that was improperly machined, structurally flawed, or not delivered on time could undermine safety or cause downtime and operating costs to soar. Uncompromising quality has always been essential. Through determined effort, both G&H and our products developed a reputation for dependability.
By the early 1990s, we were experiencing remarkable growth in demand for two product lines in particular: perforating guns and expendable plugs. Following our belief in change for the better, we adjusted our business model accordingly and set about becoming the industry’s “Plug & Perf Powerhouse.”
Today, we employ over 300 people. We have 120,000 sq ft of manufacturing space at our ISO 9001:2015 certified manufacturing facility in Northwest Houston. We operate strategically located warehouses in major U.S. oil and gas producing regions. We have earned 52 U.S. patents (awarded and pending).
With over six decades of accumulated knowledge, innovative research and development in materials and processes, and state-of-the-art production and inspection equipment, our craftsmanship and capabilities are unmatched.

THE LEGEND
Since acquiring G&H in 1983, Ed and Janan Kash dedicated their business to taking a personal interest in customer’s success – no matter how large or small. Unrivaled devotion to clients, staff, and engineers not only led to explosive growth for G&H, but ultimately set wholesome roots and innovative standards for the future of manufacturing. Though Ed still likes to play with industrial grade lasers, you’ll likely spot him and the Mrs. at the family ranch enjoying retirement.

THE LEGACY
Jimmy and Danny Kash, sons of Janan and Ed, are the fearless leaders propelling G&H to greater heights. Growing up around the business has inspired them to continue the company’s legacy of providing high-quality metal products and dedicated customer service, all while pushing themselves to expand the business in new, innovative directions. With their bold and creative vision, the future looks bright with the next generation in leadership.
THE FUTURE
G&H ranks number one among our competitors for perforated guns and number five among our competitors for expendable plugs. We have sold over 7.6 million perforating guns in the last ten years alone and our products have been used in 135 unique customer locations. Our client roster is intensely loyal and includes all industry leaders in upstream oil and gas. The goal is simple: be number one and stay number one. Through constant product innovation and recruitment of talented team members, we never stop evolving and shaping our future.

BOTTOM-SET PLUGS DON’T WORK, BUT DISSOLVABLES STILL CAN.
Many operators tried dissolvables early on and walked away after disappointing results. But dissolvables weren’t the problem. The design was.
Bottom-set plugs removed the mandrel and shortened the tool to reduce magnesium cost. That compromise sacrificed the structure needed to maintain reliable isolation.
Now that dissolvable materials are more affordable, operators no longer have to accept that compromise. Top-set fixes the problem.

We’re looking for a Business Intelligence Analyst who knows how to turn data into actionable insight. You’ll be working across teams to analyze performance, build reporting, and support real operational decisions — not just dashboards. If you’re comfortable digging into data and delivering answers that actually impact the business, take a look.

BOTTOM-SET PLUGS DON’T WORK & THE DATA IS NOW PROVING IT!
For years, operators suspected something wasn’t right with bottom-set dissolvables. The field experience was already telling the story. Now the data is starting to confirm it.
Recent reports from DarkVision and other studies suggest bottom-set dissolvable plugs can fail at rates approaching 40%. Isolation failures erase any savings from a cheaper plug.
The data confirms what the field has already experienced - bottom-set designs fail to deliver reliable isolation.

Next week, we are back in beautiful Lake Louise for the SPE Drilling & Completions Workshop. Stop by Booth 5 to connect with our team and learn how our integrated plug-and-perf systems are helping operators improve efficiency, reliability, and performance across every stage.
BOTTOM-SET PLUGS DON’T WORK�BECAUSE PLUGS NEED LENGTH AND MASS.
Successful plugs aren’t tiny. They require enough length and mass to maintain compression on the sealing element and hold slips engaged under load. Composite plugs have always followed this principle. That’s why they are longer and built around a mandrel.
Bottom-set dissolvables were designed to be as short as possible to reduce magnesium cost. That design decision removed the structure needed to maintain reliable isolation.
Short plugs may save material. But they don’t hold pressure.

Today we celebrate the resurrection of Christ and the hope, grace, and new life it represents. Wishing our customers, friends, and families a blessed and meaningful Easter.
