DRILLING OPERATIONS PLANNING AND DRILL DECK STRENGTHENING FOR EXTENDED-REACH WELLS FROM AN EXISTING PLATFORM

With the ever-increasing need to maximise the efficiency of capital spending dollars, the use of extended reach wells to explore and/or develop previously unreachable acreage from existing platforms has become a more attractive and feasible option. These types of wells can eliminate the need for platforms or difficult subsea completions. Besides challenging drilling operations problems, increased loads must be examined and compared to original platform design requirements so modifications can be made to the existing structure if required. These increased loads can come from longer casing strings, larger drilling rigs needed to handle greater depths and increased drag from high wellbore inclinations.
