چکیده:

Formation damage is one of the most important concerns in oil and gas industry.
To drill the reservoir section, drill-in fluids should be designed with appropriate physical
and chemical properties to mitigate formation damage which results in failure in field
analyses. As the number of horizontal wells and extended reach wells and also vertical
ones with open hole completions increases the need for a specialized drilling fluid to drill
the reservoir section efficiently increases as well. The properties of drill-in fluids should
be studied before taking part in the drilling operation. These properties are mudcake
properties, filtrate and spurt loss characteristics, types of bridging agents, particle size
distribution and clean up process. These are the most important aspects of appropriate
drill-in fluid which should be taken in account to drill the reservoir section effectively.
