Title: Graeme D McKay: Innovator in Wellhead Technology

Introduction

Graeme D McKay is a notable inventor based in Aberdeen, GB. He has made significant contributions to the field of wellhead technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is the "Spiral whipstock for low-side casing exits." This invention features a spiral ramp that allows tools to traverse onto the ramp and access a milled window without obstruction. The design includes an angular rotation of the ramp that can be at 180° or more, with a pitch selected to prevent equipment from getting stuck. Additionally, a guide track can be integrated into the whipstock ramp to assist the mill in following the spiral path until the correct orientation is achieved. A slot near the ramp's upper end aids in retrieval operations.

Another significant patent is the "Combination motor casing and spear." This wellhead removal tool incorporates a rotary cutter powered by a Moyno type progressive cavity pump. The stator of the motor features a gripping device with collets that face outwardly. A support shoulder on the grip assembly works with a j-slot connection to allow a cone to push the collets into a grip position, ensuring that the wellhead's internal components remain undamaged during operation. The fluid pumped through the downhole motor activates the casing cutter blades to extend and rotate, effectively cutting the casing.
