The Performance Study of High-Temperature, High-Pressure (HTHP) Corrosion Inhibitors at Sour Conditions

MECC 2023, 2023
Abstract One of the main corrosion problems faced by the oil and gas industry is HTHP (high temperature, high pressure) corrosion at both sour and sweet conditions. HTHP oil and gas fields are increasing for both onshore and offshore production.

A comprehensive review of laboratory, field and modelling studies on drilling mud rheology in high temperature high pressure (HTHP) conditions

Journal of Natural Gas Science and Engineering, 2021
Abstract As the demand for hydrocarbons increases, the search frontiers for petroleum and natural gas deposits keep being pushed towards unconventional terrains. An example of an unconventional terrain where oil and gas deposits can be found is the high temperature and high pressure (HTHP) environment. While HTHP wells can hold a wealth of resources,

Functional coatings via isocyanate-cured phenolics for anti-graffiti and via benzoxazines for high-temperature and high-pressure (HTHP) applications

Progress in Organic Coatings, 2021
Abstract In this work centering on phenolic chemistry, we investigated isocyanate and benzoxazine modified phenolic powder coatings aimed to better address a couple of industrial applications. In one aspect, allied polyurethane formulations were developed using phenolic hydroxyl-isocyanate reactions and shown to outperform conventional aliphatic ...
