... well was established by the end of the 38 th stage completion for the east horizontal well. The simulated coulomb failure stress surrounding the fault reached a maximum of 4.15 MPa, exceeding the critical value to cause the fault slip. Hence the poroelastic effects on the inferred fault were...

... of completion rates or pressures. Using optimization methods, it is possible to compute control settings that result in increased oil production and decreased water production compared to production from standard practices. In this paper, we focus on optimization using SQP with an ensemble-based approach...

..., and well completion. This is because these effects occur on scales that are very small compared to typical simulation grid blocks. In this work, we describe a modeling procedure for representing the well and near-well region that is able to resolve flow down to the scale of the completion and perforations...

... different completions that can be controlled independently. The producing life of the reservoir is 30 years and the objective of optimization is to maximize the net present value at the end of 30 years. Due to the complexity of this test case, several advanced techniques are used in order to improve...

... Abstract Complex well configurations coupled with intelligent completions offer great potential for the efficient production of oil reservoirs. One application of this technology is the use of surface adjustable downhole chokes. This allows wells to be divided into separate inflow zones...

While monthly updates are probably sufficient in most cases, operators have the option of updating weekly, daily or even more frequently in order to meet the needs of each situation. This ground breaking approach removes much of the risk from the evaluation of well completions, optimizing...

The ability to detect redundant parameters is also discussed, even those that are not apparent by simply examining the sensitivities. Our method can determine if an improvement in the match can be made, and if so how much...
