... uneconomic by Spring 2017. An analysis was conducted to determine the technical and economic viability of implementing a waterflood of the Clearfork formation to extend the life of the lease. A reservoir model of the field was created and history matched to validate reliability before predicting reservoir...

... and step rate test at the end. The analysis is based on simulation models to history match the pressure response in the injector during the polymer trial. Key realizations focusing on two aspects – polymer rheology and wellbore/reservoir fluid propagation mechanism – are presented that were used...

...Introduction The purpose of every integrated reservoir study is to obtain a predictive model and use it as a tool for future field management. Reservoir modeling and history match are two key steps of the study workflow. Even if the final history match model may be not unique, the process...

... was also history-matched (7 years of production history) to calibrate and ascertain the limits of the possible contacts for the reservoirs. The result of the evaluation is a significantly reduced volumetric uncertainty range. In one of the reservoir, there was a progressive reduction in fluid column...

As more geologic and dynamic data becomes available, an updated history match of the existing dynamic field models is required to provide more accurate simulation results for estimating reserves, optimizing production and assessing future field development opportunities. In this paper, we...

Time-lapse saturation (Pulse-Neutron) logs were available for a large number of wells indicating the state of water saturation in multiple locations in the reservoir at different times. The data-driven, full field model was trained and history matched using machine learning...

Confidence in simulation predictions depends on the strength of evidence for the input data, quality control of the model, robustness of the history match, and whether there is independent evidence supporting predictions. We explain the principles...

It was agreed that in order to meet the project deadline, turnaround time of a history match simulation run should be within one day. The preferred design was to get to about three million active cells, deemed reasonable...
