Title: John Milne: Innovator in Drilling Technology
Introduction
John Milne is a notable inventor based in Anchorage, AK (US). He has made significant contributions to the field of drilling technology, holding a total of 4 patents. His innovative designs have improved the efficiency and safety of drilling operations.
Latest Patents
One of Milne's latest patents is the Retrievable Seal Guide (RSG). This device is designed for installing a seal stem in a polished bore receptacle. The RSG features an outer grapple, a mandrel, and a bullet nose guide. The mandrel is spring-loaded, and the design includes a plug with an o-ring. Notably, the bullet nose has an opening, and a channel runs the length of the device. For tight formations of non-perforated liners, the plug can be replaced with a stainless-steel ball that acts as a check valve. As the RSG is pulled out, the guide compresses the spring, allowing for easy withdrawal.
Another significant invention is the High Expansion Wedge (HEW). This drilling wedge includes two wings that extend from the sides, preventing a milling assembly from sliding past or moving off to the side. The wings ensure that the milling assembly remains in the correct position, facilitating a proper exit point in the casing. The wings are retracted during deployment through a narrower pipe and are extended once the HEW is properly positioned.
