Abstract Advancement in High Performance Water Based Mud (HPWBM) coupled with a
deeper understanding of shale and chemical interaction has taken a leap in recent years …

Abstract In Southern Europe, a field known to have extremely unstable formations was
drilled successfully with a specialized high-performance water-based fluid (HPWBF). Prior to …

In the UAE, drilling intermediate sections that contain highly dispersive clays with water-
based muds almost always leads to mechanical instabilities in the form of pack-offs and tight …

Hole stability and differential sticking are main challenges while drilling through commingle
shale & sand sequences. Conventional mud systems cannot ensure wellbore stability and …

Drilling through the thick shale sequence (Oligocene to Paleocene age) of Cauvery offshore
showed severe wellbore instability in the past due to incompatible mud program that …

Abstract Objectives/Scope A major Operator in Kuwait have used historically Non-Aqueous
Fluid (NAF) to drill the buildup section through the challenging shale formations, mainly due …

It is a challenge to drill in highly deviated or horizontal holes with high differential pressures.
Wellbore instability, differential sticking and mud loss are frequently encountered problems …

Wells drilled in the direction of minimum stress are potentially more favorable for reservoir
development and optimal production. In such a situation, hydraulic fractures grow …

Abstract Kuwait Oil Company (KOC) was planning further development of the Sabriyah (SA)
and Raudhatain (RA) fields by drilling a number of horizontal wells. Both fields presented …

Abstract Description of Proposed Paper As the drilling industry has pursued more horizontal
wells in water-reactive shales, the challenges from wellbore instability and high friction (eg …
