When it comes to pressure control disks, there’s only one name trusted around the world for superior wellbore isolation: MagnumDisk™. But what you don’t know is the interesting story behind the design of the MagnumDisk™. When our President/CEO Lynn Frazier was a young boy, his father called him to the chicken coop one evening to gather eggs. His father handed him an egg and placed it in his hand vertically, he told him to squeeze it as hard as he could to see if he could break it, Lynn cupped the egg in his hand and squeezed as hard as he possibly could, but the egg wouldn't break. The egg’s unique shape gives it tremendous strength despite its thin shell. Eggs are similar in shape to a three-dimensional arch, one of the strongest architectural forms.
Fast-forward to 1997, like all Magnum products, Lynn was presented with a challenge to develop a specific solution to a customer’s problem. At this time, all existing differential tools had a thick flat glass as a barrier and were very difficult to break. The customer needed a barrier as thin as possible, but as strong as possible to be able to hold back enormous pressures. During the design phase, Lynn reflected back on that moment with his dad in the chicken coup and created the one of a kind design for the product we now call the MagnumDisk™. If you look at the shape of a ceramic disk, the top of the disk is almost identical to that of an egg.
In July of 1999, Lynn was issued his first patent for the MagnumDisk™ and it continues to be one of the most popular Magnum products because of its simplicity, reliability and cost effectiveness. See for yourself.
