PREPARATION OF THE DRILLING MUD PROGRAM
To estimate a drilling fluid program, it is necessary to know the geological and technical conditions (GTО - geological and technical order), it describes the design of the well, lithology, diameters of the well and casing pipes, as well as the parameters of the drilling fluid to be observed and provided by the customer
As well as additional information such as the reservoir characteristics, expected complications, stratigraphy, lithology, reservoir conditions and data from neighboring previously drilled wells with all the resulting problems encountered during the process .
After careful study of the above information, a drilling fluid program is prepared. The most recommendable drilling fluid system is so far proved to be FORTIDRILL system. It insures the safe opening of productive formations, minimal contamination of reservoirs, the stability of the trunk and the walls of the well.
The advantages of FORTIDRILL system are high–quality well construction, easy retention of the specified drilling fluid parameters, fast processing if necessary to change any parameters. This system is the most resistant to lithological changes and aggressions of all kinds of contamination with salts and carbonates. The system can also be stored and reused at the next passing wells, proving the stability.
