RIPI Develops Encyclopedia of LCM

RIPI Develops Encyclopedia of LCM
TEHRAN Nov. 28 (RIPI) -- Experts at the upstream campus of the Research Institute of Petroleum Industry (RIPI) have put together an encyclopedia of Lost Circulation Materials (LCM) and new drilling materials.
Dubbed as the "Kymia Project", the work is aimed at providing a reference for manufacturing crucial chemicals and additives for developing drilling liquids in a bid to tread forward towards self-sufficiency in the petroleum industry in Iran.
Alireza Nasiri, the project leader and head of the drilling technology research at RIPI, said the project encompasses three sub-projects which are design and formulation of light and superlight liquids, design and formulation of liquids to control loss circulation, and design and formulation of liquids for controlling shale layers. Loss circulations is considered as one of the main factors that incur huge costs on drilling operations.
The encyclopedia offers formulations which have recently been introduced in the drilling industry and enjoy many advantages in comparison with former LCM solutions, said Nasiri.
The solutions also are very environmentally friendly and are developed by natural raw materials, he added. RIPI LQ is one of these solutions which has been introduced by the campus for the first time. It has been tested at Charak well and has retrieved good results.
LCM is a solid material that is intentionally introduced into a mud system to reduce and eventually prevent the flow of drilling fluid into a weak, fractured or vugular formation.
This material is generally fibrous or plate-like in nature, as suppliers attempt to design slurries that will efficiently bridge over and seal loss zones. In addition, popular lost circulation materials are low-cost waste products from the food processing or chemical manufacturing industries. Examples of lost circulation material include ground peanut shells, mica, cellophane, walnut shells, calcium carbonate, plant fibers, cottonseed hulls, ground rubber, and polymeric materials.
