Associated Petroleum Gas 2016 / key applicants

Recent Inventions / Brief Overview

Useful utilization of associated petroleum gas, instead of just flaring it, is an important issue in today’s energy industry, both in terms of reducing greenhouse gas emissions in the environment and the efficient use of natural resources. Despite the massive efforts of governments, environmentalists, oil companies and other concerned participants, the total volume of associated petroleum gas being flared around the globe has been increasing in recent years. According to Global Gas Flaring Reduction data, about 150 billion cubic metres of gas is being flared annually in the world, which is approximately 4% of the total annual volume of natural gas production. However, there is a consistent trend of decline in this process. Specific volume of gas flared per one barrel of oil produced around the globe has dropped by more than 13% during the last seven years. Apart from organizational and administrative measures in different countries, this process is heavily influenced by innovative activities of participants, including developing state of the art technical solutions.
Below is a patent activity review for key applicants in the field of associated petroleum gas utilization. The present review is based on the analysis of patent applications filed to the leading patent offices of the world in 2016.

In total, 217 patent applications were found in 2016, filed by 79 applicants – residents of 16 countries. The following table represents the top 10 applicants:
