Smart lost circulation materials for productive zones [PDF]
Journal of Petroleum Exploration and Production Technology, 2018 Lost circulation has been a serious problem while drilling that may lead to heavy financial costs in the form of lost rig time and lost mud fluid. In severe cases, it can lead to well blowout with serious environmental hazards and safety consequences ...

The Effect of Nano Materials on Lost Circulation Control of Azkand Formation in Khabaz Oil Field
Journal of Engineering, 2020 Experimental tests were carried to control lost circulation in the Khabaz oil field using different types of LCMs including Nano-materials. A closed-loop circulation system was built to simulate the process of lost circulation into formations.

Performance Evaluation Of The New Natural And Environmentally Friendly Material For Lost Circulation Control At High Pressure And Hight Temperature [PDF]
Eurasian Journal of Science and Engineering, 2023 Lost circulation refers to the loss of a part or whole drilling fluid into the formation and is considered as one of the most challenges in drilling operations. It could be occurred either naturally in highly fractured formations or induced by excessive

Lost circulation control materials. Progress report [PDF]
, 1994 Work in FY 94 continued to investigate the use of calcium phosphate cements as lost circulation control materials for geothermal wells. The calcium phosphate cements were produced by reacting calcium aluminate cement with sodium phosphate compounds. Pumpable formulations with thickening times up to two hours at temperatures between 25 to 90{degrees}C ...

Materials for Controlling Severe Lost Circulation - Laboratory Evaluation
SPE Latin America and Caribbean Petroleum Engineering Conference, 2017 Abstract Lost circulation is still today one of the most costly problems for oil and gas operators. It may occur into permeable formations, depleted zones, induced or nature fractures and cavernous formations while drilling, cementing or during workover jobs in the well.
