Nowadays, UnderBalanced Drilling (UBD) technology is widely applicable in the petroleum industry due to its advantages to an overbalanced drilling operation. UBD success depends on maintaining the drilling fluid circulating pressure below the reservoir pore pressure during operations. One of the main prerequisites of a successful UBD operation is the correct estimation of the pressure profi...

The aqueous mixtures of light gas molecules under low-temperature and high-pressure conditions are candidates to form gas hydrate clathrates. The formation of gas hydrate may lead to various problems and extra charges in natural gas production and processing. The presence of hydrate crystals forming a stable solid phase can potentially block the wells, pipes, and process facilities. To avoid su...

The growing energy demand in the world, as well current geopolitical situation, require countries to additional investments exploration and production of hydrocarbons from their own sources. This means that companies must develop new fields which have remained undeveloped until now mostly because extremely harsh environment where they are located (deep sea, high temperature, pressure, heavy oil...

Abstract This work investigates the efficacy of a biodegradable natural product, litchi leaves powder (LLP) as filtration loss control agent in water-based drilling fluid formulations. In order to evaluate potential (LLP), strict protocol experimentations according API (American Petroleum Institute) standard has been followed. The experimental outcome showed that before hot rolling and after mu...
