People: Unlike when I started (1964). Many of today's oil fields are controlled and run by Indigenous companies,(75%) often worked by their own engineers and people. We as consultants have an ever increasing part to play and our experience that is often called on in troubled times. You have only yourself on offer. It therefore stands to reason that what you offer is of quality: Professionalism, Ability, Experience, Prediction and Advice, "not always an easy task". But for the true professional this is not a problem. Computers and the Internet now make communication easier and information is just a phone call away. Many of the major data bases that use to be lock away are now open, for the price of an email to collect the password. For many the industry is not a job but a way of life. The computer will never take over but is a good tool. You will still need good People. Training never stops. As we grow older so we gain experience. As we climb the ladder we continue to learn. Often this learning will come from the people we teach and train. Such knowledge is added to the data bank we call the mind. Experience has taught me, never turn your back on an idea and that often as one door closes other open. What often confuses people is, "The problem" The problem can often be the "Answer" By process of elimination we work our way to the problem, that being the answer ? Under normal drilling conditions the drillfloor is supervised by the driller, and it is the drillers responsibility to keep the rig safe,  such a position can be very stressful at times, planning a well is one thing, drilling it is another, although the drilling parameter are predetermined there is no telling what Mother Nature has in store, and sometimes she can be a bitch, the driller is also responsible for the hands-on training his crew: "hence the saying there are no bad crews just bad drillers"? By the time a person has reached the position of driller, they would have attended many courses, such course would have included, Well Control, Casing and Cementing, Rig Safety, Practical Drilling, Stuck Pipe, some form of management school and any other schooling that is could help in such position, but this is only the beginning most of the learning start when taking over the position The drilling crew would typically be compiled of the following personnel  The Driller The Assistant Driller The Derrick Man The floor men Not all would be on the drill floor while the rig is drilling,  depending on the type of rig some would have other areas to cover. such as the derrick man he would be keeping an eye on the drilling fluid use for keeping the hole clean and safe, often one of the floor crew on a land rig would also be the motor man working with the mechanic The drill floor is supported by the following personnel The Toolpusher Tour Pusher Crane Operator Mechanic Electrician Deck crew or roustabouts this section of the crew work 12 hours on and 12 hours depending on the type of rig being worked From the operators side (the oil company) it will be supported by: The company witness, often referred to as the drilling supervisor an company man the Mud Engineer the Directional driller the Mud Loggers, There are of course many other people on or around the rig but most are not directly involved with the drilling or may only arrive on the rig to perform service type work or come out for completion or problem type work such as fishing junk from the hole  On some of the offshore rig, in  particularly the large jack-up rigs and some semi-submersibles the OIM (offshore installation manager) is the most senior member of management team, on smaller rigs and land rigs the Tool Pusher will usually be the most senior member of management team, In some parts of the world, in particular the UK oil and gas sector it is mandatory by law to have an "OIM" on board at all the time on all "installations" i.e. Production platforms and FPSO's (Floating Production Storage and Offloading Vessels) The "OIM" is responsible for all matters of Health and Safety and any emergency situations that may arise. This means that he or she is responsible for managing the response to an emergency. The OIM also manages all day to day aspects of the Oil and Gas production operation this would generally include; Budgets, Personnel, Production, Maintenance, Logistics (helicopters/supply boats/dive vessels etc) but not the drilling operation un less it was using un-safe drilling practices, Nowadays we are seeing more offshore drilling superintendent/drilling managers moving into the field and in some cases replacing the OIM, most are people that have worked up through the ranks and from the drilling side, they have the same responsibility’s as the OIM but are more drilling orientated than most OIM's, working with them would be the toolpusher On offshore oil rigs, tool pushers are Department Heads, they oversee the drilling department. They report to the rig drilling superintendent or OIM, also under the senior persons charge would be the Senior Mechanic, Senior Elections and Barge Engineer. Tool pushers are in charge of keeping the rig in all necessary tools and equipment, supplies, etc. They will also work closely in conjunction with the company man in regards to the actual drilling of the well. Usually a toolpusher has started at the bottom and worked his way up and has been in the industry for a number of years, Up until the start of the 80's the toolpusher ran the rig, however in recent times, the tool pushers have taken on somewhat of an administrative role, frequently doing paperwork related to the rig crew regarding payroll, benefits, etc. it is this that allowed the position of OIM to move into the drilling operations, allowing the toolpusher to use their experience in drilling, Nowadays most large rigs have a night and day toolpusher. The drilling rig is the senior service company, and is supported by many other service companies, the supporting service companies or not directly controls by the rig personnel but by the operating company (oil company) however the rig personnel often carry out their work under the supervision of their engineers It is therefore possible for many of the drillers and toolpusher to know almost as much about the tools such companies run as the engineer themselves
