Abstract:
1. A computer-implemented method of designing an oil well, comprising: (a) defining a plurality of design parameters each of which is determined by a number of input data, the input data for at least some of the parameters including one or more of the other parameters; (b) providing, for each of the design parameters, conditions or constraints which must be met; (c) using a microprocessor, selecting input data for a first design parameter such that the parameter falls within the conditions or constraints; (d) using a microprocessor, varying the input data for the first design parameter to achieve an initial optimisation of the parameter; (e) using a microprocessor, for a second design parameter whose input data includes the first parameter, selecting other input data such that the second parameter falls within the conditions or constraints; (f) using a microprocessor, varying said other input data for the second design parameter to achieve an initial optimisation of the parameter; (g) using a microprocessor, varying the input data for the first parameter to further optimise the second parameter; and (h) repeating steps (e) to (g) for the remaining design parameters, wherein the design parameters fall within the conditions or constraints to be met for designing an oil well.
