Reliability Estimates

In the direct methods for evaluating reliability of industrial machinery, performance indicators are ascertained from statistical analyses of the randomly fluctuating response variable using pre-established threshold levels of acceptable performance. The accuracy of the results depends directly on the rigor of the probabilistic procedure employed. In this paper, a new approach for calculating the probability measures of the randomly enveloped areas of the response excursions about any given threshold level is presented. The area excursions contain important information on both the time durations of the excursions as well as their intensity levels above the critical value and thus give a direct reliability estimate of the system performance. The mathematical development of the method, derivation of reliability indices, sample calculations, and life estimates are included.

Reservoir Simulation Model

Most of the current research and commercial reservoir simulators lack the capability to handle complex completion details like perforation tunnels in a simulation study. In most common applications, the simplified handling of completion complexity in reservoir simulations is not expected to introduce significant error in simulation results. However, it has been found that under certain circumstances, especially in high rate wells that have become more and more common in deepwater oil and profilic gas development, exclusion of the complex completion details in a reservoir simulation model would lead to nontrivial errors. New equations have been proposed to assess the needs to incorporate completion details in a reservoir simulation study based on the understanding of the fluid flow in a formation, the fluid flow along a wellbore and the fluid flow through perforation tunnels if exist. A series of sensitivity studies with different completion options under different flow and reservoir environments has been conducted to provide some guidance to improve well performance prediction through reservoir simulation. Impacts of key parameters like perforation density, perforation diameter, perforation length, wellbore length, borehole diameter, well completion configuration, well placement, reservoir permeability, reservoir heterogeneity, pressure drawdown, etc, have also been investigated.
