Conventional drilling fluid (DF) technologies commonly fail to meet many of the
requirements of modern drilling under various harsh subsurface conditions, particularly …

With the growth of deep drilling and the complexity of the well profile, the requirements for a
more complete and efficient exploitation of productive formations increase, which increases …

Fluid loss is a well-known problem while drilling oil and gas wells. Minimizing the fluid loss
and forming low permeable thin filter cake by using a suitable filtration control additive as an …

With the exploration and development of deep and ultra-deep oil/gas resources, higher
challenges have been placed on the performance of water-based drilling fluids (WBDFs) …

High performance (HP) water-based drilling fluids are particularly advantageous compared
to conventional water-based systems because they provide faster penetration rates …

Deepwater drilling using high-pressure and high-temperature (HPHT) drilling fluids draws
significant attention for the quest of increasing energy demand. In this regard, selecting …

A new, environmentally safe water-based polymer system has been developed for drilling
applications with temperatures up to 232 C (450 F) and high pressures. The system …

As we approach an age of deeper discovery and petroleum producing wells with hostile
environments, the industry need for an elevated-temperature, high-density, low-solids, and …

Ultra‐high temperature dramatically deteriorates rheological properties and filtration
performance of water‐based drilling fluids (WBDFs), especially for a salt‐gypsum formation …

Exploring deep and ultradeep wells has rapidly become more significant to meet the global
demand for oil and gas. The study of rheological and filtration-loss properties is essential to …
