أخي التباوي المعذرة لإنشغالي هذه الأيام 0000
مع إن طلبك ليس من تخصصي ولا أعرف إن كان أحداً ممن لهم علاقة بها الموضوع ممكن يفيدونك ولكن النت يحتوي على الكثير من المعلومات لو حاولت البحث ؟

When oilmen who are daily involved in the mathematics of oil field engineering and economics start to point out the many factors that go into decision-making, the nonexpert feels, justifiably, that the world will end long before all the possibilities of a given situation can be explored. The outsider seizes a few terms to help serve him as guideposts of understanding.
There is, for example, a right-cost logic that governs the evolution of an oil field. It seems a simple enough term. However, it embraces in its implications a number of elements: the field itself, the field's . Every possible set of variables, or at least a mathematically significant number of them, must be studied.
Fortunately, high-speed computers make it possible to complete a lifetime of hand calculations in a single day. An oil field can thus be "produced" on paper under a number of different sets of conditions. Rates of production, for example, can be altered. Demand figures can be changed. Reservoir pressures can be reduced at different rates. And a range of production costs can be explored.
Out of this succession of computations a moment comes when the per-barrel cost of placing a field on production fits into the framework of right-cost logic. This means that the per-barrel development cost of a given field, at a given rate of production, at a given time is in balance with the cash register realities of the market. The time has then come for management to risk the necessary funds.
At the time management had to decide about how to meet the demand for more crude, the engineering and economic studies made the advantages of placing the field in production increasingly apparent. Continuing studies showed that cost data were beginning to fit within the limits dictated by right-cost logic.
Further, oil was becoming a more attractive development choice for another reason. The reservoir pressure had dropped faster than anticipated in the preliminary predictions of the pressure-production behavior of the field. Since these preliminary predictions are based on a very limited amount of information (one of the reasons why there is a large element of risk in the development of an oil field), it is not unusual for the actual performance of a given field to be different from that predicted in the preliminary estimates.
A more rapid than anticipated pressure decline meant two things. The target year for expensive gas or water injection would have to be moved forward. And, the long-range economics of oil would have to be adjusted to take into account the capitalization of pressure maintenance at an earlier date than had been predicted. In dollars-and-cents terms, the per-barrel cost of producing oil over its life span had risen—and so had oil's opportunity.
