Будущее телеметрии и геофизических исследований в процессе бурения в Арктике

The future of MWD and LWD Operations in the Arctic  

Abstract:
Few locations present as many challenges as drilling in Arctic. It is one of the most hostile environments in the world. It contains some of the most remote locations, the toughest logistics challenges and the largest gaps in infrastructure on the planet. While the industry has moved progressively over the past decades to meet these challenges, one company’s solution to reduce risk to personnel and the environment and to optimize cost was to do directionally drill and log the well remotely. Theoretically, wells could be steered and controlled from the comfort of your couch at home; millions of dollars’ worth of technology controlled from thousands of miles away. With advances in data, communication and transmission technology, we have the capability to make it reality. This is exactly what was done.
The workflow is not only about monitoring or support from town offices but also a fundamental paradigm shift where the Directional Drilling and Measurement While Drilling (MWD) crew is not physically located on the rig. In order to accomplish this, a major transformation was needed to ensure that process safety was not compromised by introducing additional risk to the operation. Technologies had to be qualified and workflows had to be modified ultimately resulting in redefining roles and responsibilities. There was also a major challenge to convince operators to allow the control to come from a source external to the rig. There are many associated risks with such operations. These risks include loss of connectivity, untested methods for diagnosing tool failure and hardware failure to name a few.
This presentation begin with a brief history of Remote Operations (RO) indicating major milestones. The challenges of implementation of RO centers, and the prevention and mitigation of the associated risks are discussed. Given the success in implementation of a major RO center in the Arctic, the methods and technologies used to achieve success is discussed with some specific focus on the Arctic operations. Many of the challenges and methodologies will be supported by details of implementation in the Arctic environment.
