SUMMARY:

In offshore oil exploration, the construction of a well requires long and complex operations,
which results in high costs, mainly related to the rental of drilling rigs. it is essential to
analyze the sequence of operations required for its construction, particularly concerning its
structure, given its importance throughout the well's lifecycle, in order to seek a reduction in
errors and execution time. A promising analytical approach is to use historical data in the
planning of new offshore operations, aiming to bring more predictability to the assessment
and design process of new wells. To do so, operational sequence models of the well structure
were developed based on actual drilling schedules to establish parameters for duration and
anomalies for production, injection, and special wells. The analyses were conducted using a
database of drilling schedules carried out by an oil company. The schedules were imported
into spreadsheets, where they are grouped according to well type, and specific well structure
activities are separated from others to establish the operational sequence and its parameters.
The developed models can be used for both the design of new wells and the evaluation of previously executed schedules, aiming to reduce errors, downtime of equipment and personnel, and, consequently, cost reduction.
