Abstract: | In drilling operation, a large saving in time and money would be achieved by reducing the drilling time, since some of the
costs are time-dependent. Drilling time could be minimized by raising the penetration rate. In the comparative optimization
method, by using the records of the first drilled wells and comparing the criteria like penetration rate, cost per foot and
specific energy, the drilling parameters of the next wells being drilled can be optimized in each depth interval. In the mathematical
optimization technique, some numerical equations to model the penetration rate, bit wear rate and hydraulics would be used
to minimize the drilling cost and time as much as possible and improve the results of the primary comparative optimization.
In this research, as a case study the Iranian Khangiran gas field has been evaluated to optimize the drilling costs. A combination
of the mentioned optimization techniques resulted in an optimal well which reduced the drilling time and cost considerably
in comparison with the wells already drilled. |
