Controlling severe to total lost circulation in naturally fractured/vugular formations has always been challenging, especially in carbonate formations across the Middle East. In these environments, conventional particulate lost circulation materials

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 spots due to highly laminated shale formations containing a high

Managing severe to total lost circulation can present major challenges in naturally fractured formations. Particulate lost circulation materials (LCMs) have been used to manage lost circulation for many years; however, current LCMs are not efficient

Summary Lost-circulation materials (LCMs) are often used to mitigate the loss of drilling fluids into subterranean formations. Well-known LCMs include ground marble, graphitic carbon, and cellulosic particulates. The carrier fluid’s ability to susp

Numerous lost circulation materials (LCMs) are sold in the global market to cure losses in highly fractured formations, but the success rate remains minimal. Lost circulation (LC) is a common challenge of global operators and service companies during

Drilling fluid designs for wellbore strengthening have been improved through the development of engineered nutshell (ENS) products, which have replaced conventional marble for the larger particle sizes. Marble particles greater than ~400 microns are

A new laboratory work procedure has been developed to evaluate and test the performance and effectiveness of chemical-sealant-based loss circulation materials (CS-LCMs), which are often used in cases of severe-to-total losses. These unconventional te

Wellbore strengthening generally refers to the practice of enhancing the lost circulation limit of a (fractured) wellbore through proper design of the drilling fluid system and downhole circulation program. Particulate-based additives, known as lost

Lost circulation is an extremely difficult challenge to overcome in areas with large natural fractures. Few lost circulation materials (LCMs) are capableoftreatingsuch zones where severe to total losses occur, particularlyin the reservoir sections. P
