PLANNING AND IMPLEMENTATION OF UNDERBALANCED DRILLING IN BRAZIL
ABSTRACT: UNDERBALANCED DRILLING HAS BEEN EXTENSIVELY USED MAINLY IN USA AND CANADA. IN BRAZIL ONLY IN RECENT YEARS THIS TECHNOLOGY STARTED TO BE APPLIED TO DRILL SOME WELLS ON THE AMAZON, NORTHEAST AND SOUTH REGIONS.
THIS ARTICLE SHOWS RECENT OPERATIONS CARRIED OUT TO IMPLEMENT THE TECHNOLOGY OF UNDERBALANCED DRILLING IN THE COUNTRY. ALSO THE ARTICLE RELATES THE DEVELOPMENT OF NEW EQUIPMENT (INCLUDING MULTIPHASE SEPARATORS). THE MAIN DIFFERENCES BETWEEN CONVENTIONAL AND UNDERBALACED DRILLING ARE COMMENTED.
OPERATIONS PERFORMED IN BRAZIL INCLUDED AIR, GAS AND FOAM DRILLING. THIS WORK SHOWS ADVANTAGES AND MAIN OPERATIONAL PROBLEMS FACED WHEN USING THE TECHNOLOGY. THE DEVELOPMENT EFFORTS CURRENTLY BEING MADE TO IMPLEMENT LIGHT WEIGHT DRILLING FLUID ON OFFSHORE DEEPWATER ENVIRONMENT ARE COMMENTED AS WELL.
KEY WORDS: DRILLING, UNDERBALANCED DRILLING, LIGHT WEIGHT DRILLING FLUID.
