"Lost circulation materials (LCM's) have been widely used to avoid or stop losses. Due to a large number of current available LCM's and their different applications, classification of LCM's is very important. The most recent LCM classification was published around 50 years ago, and this paper intends to fill this gap with an updated classification including conventional and new technologies. Lost circulation materials and treatments are re-classified into various categories based on their appearance, applications, chemical and physical properties.

Wells in Basra's oil fields are highly susceptible to lost circulation problems when drilling through the Dammam, Hartha, and Shuaiba formations. This paper discusses the most recent treatments, which are used in Basra's fields with integrated analysis and updated classification. In addition, the best lost circulation strategy of remedies will be presented to mitigate or stop this problem.

Sometimes it is difficult to regulate mud losses by using conventional lost circulation materials. Also, the cost of these materials are expensive, so it is important to find techniques and mechanism to live with some degree of losses. This work will also demonstrate methods that were used to ameliorate lost circulation without the use of lost circulation materials like liner hanger and casing-while-drilling, floating mud cap drilling, aerated mud, foam, air or mist with cases histories in Basra's fields.

This paper discusses the most recent developments in lost circulation materials and treatments, in addition to the presentation of a comprehensive summary of today's available LCM's, treatments and alternative approaches with their applications"--Abstract, page iv.
