HPHT Focus Intro

The array of papers received for review this year covers a wide spectrum, both in applications and research, which indicates that the exploration and production (E&P) industry is actively working to monetize high-pressure/high-temperature (HP/HT) reservoirs.

The pandemic has already put an indelible mark on the industry during the past 2 years. The present geopolitical scenario is posing a serious challenge to countries’ energy security. The oil and gas sector is confronted with the biggest task in society—addressing climate change. The E&P sector is going to face stiff challenges in the coming days, with the word “petroleum” being substituted by the word “energy” to cover wider possibilities. Eminent actions are distinctly visible in the strategic planning of fossil fuel companies and the capital-expenditure investments in the E&P sector. Companies are shifting priorities toward diversification, resilience, and decarbonization.

Safety continues to dominate HP/HT operations and will do so in the future with more-stringent measures and compliances. Cost-effective technology solutions blanketing the entire domain of HP/HT activities will provide exploitation on a sustainable basis with collaboration between industry and academia.

While reviewing the papers, every attempt was made to provide a fair representation that cuts across the HP/HT domain to show the reader what is happening in the industry, both in the field as well as in research, over different geographical locations. Several of these case studies presented inspiration tied to the indomitable human spirit that can overcome challenges through innovation.
