Craig Milne

Title: Craig Milne: Innovator in Optical Fiber Technology

Introduction

Craig Milne is a notable inventor based in Elstree, Hertfordshire, GB. He has made significant contributions to the field of optical fiber technology, holding a total of 3 patents. His work focuses on enhancing the capabilities of wireline optical fiber sensing systems, which have important applications in various industries.

Latest Patents

One of Craig Milne's latest patents is for a "Wireline Optical Fiber Sensing" system. This innovative technology utilizes an enhanced Distributed Acoustic Sensing (DAS) system, which comprises a DAS interrogator and a high reflectivity fiber. This system allows for the deployment of a high reflectivity fiber as part of a wireline intervention cable that can be temporarily lowered into a well. This approach eliminates the need to permanently cement the optical fiber cable into the well. The wireline cable is sensitive enough to detect micro-seismic activity and low-frequency strain, offering many more measurement points and channels than traditional wireline deployed geophones and tiltmeters. Additionally, the cable requires no clamping and can be easily and quickly transferred between wells.

Another significant patent by Milne is the "Method and System for Downhole Object Location and Orientation Determination." This invention involves a downhole device designed to be co-located with an optical fiber cable. The device includes an accelerometer or other orientation-determining means that can ascertain its positional orientation relative to gravity. It also features a vibrator or sounder that outputs positional orientation information as an encoded and modulated acoustic signal. A fiber optic distributed acoustic sensor detects this acoustic signal and transmits it back to the surface, where it is demodulated and decoded to obtain the positional orientation information. This technology is crucial during perforation operations to prevent inadvertent damage to the fiber.
