Chapter 12 –  MANAGING DRILLING OPERATIONS                       293






                    These areas of responsibility must be defined before operations begin.

                 All supervisory staff (whether operator, contractor, or service company)
                 must understand and follow the procedures laid down.

                    On a typical dayrate operation, the drilling supervisor will set out a
                 daily program of work for the next 24 hours. This is then discussed with
                 the toolpusher so as to ensure that the contractor has some input and is able


                 to flag up any conflicts. For instance, the drilling supervisor may plan to
                 test the blowout preventer on a test stump in readiness for nippling up the
                 BOP later on. However, the toolpusher may be aware of some equipment
                 problem that prevents the test from occurring until a later time. (A test
                 stump is a “false” wellhead spool to which the BOP can be connected and
                 tested. Once the BOP is then nippled up on the actual wellhead, only the
                 last connection needs to be tested. This can save a considerable amount of
                 rig time.)

                    It is good practice for the main supervisory staff on the rig to meet at
                 least once a day to discuss the upcoming program.



                             Decision Making in the Of ce

                    Each day, usually sometime around 6:30 a.m., the drilling supervisor
                 transmits a daily drilling report back to the office. Previously this was by

                 telex, but now computerized reporting systems are the norm. With high-
                 cost operations, data from the rig can be constantly streamed to a real-time
                 data center, where it can be analyzed by specialists in different disciplines.
                 This data also can be monitored in the drilling office.


                    In a typical drilling office that has several rigs working, a morning
                 meeting is held, chaired by the drilling manager. Each drilling

                 superintendent describes briefly the operations on the rig, any problems
                 that have occurred or are expected, and other relevant points. This is a
                 good forum where others in the meeting may give advice. It also keeps
                 everybody updated on what everybody else is doing. People from
                 other departments or sometimes from the drilling contractor or service
                 companies might attend, though this is not usually the case.

                    Although the drilling superintendent responsible for a rig works office
                 hours, the rig can contact the responsible drilling superintendent (DSupt)
                 any time if problems occur.
