Paper Number: SPE-192053-MS
... complication for the interpretation of the recorded pressure data was the potential for gauge drift to occur – this was incorporated into the uncertainty range used in all three interpretation methods. The observed relative performance for the various gauges used during the well test is also reported...

... but, unfortunately, all real world data is imperfect. Quantifying the value of this imperfect information requires assessment of either (i) the likelihood of the appraisal activity correctly resolving the value of an uncertainty, or (ii) the impact of the activity on the post-appraisal uncertainty range, both...

... by eigenvectors of the data corresponding to the largest eigenvalues. Divided into 10 groups using K-means clustering, we choose the same number of ensembles from each group. Clustering helps to sample unbiased ensembles. It can be a biased sampling without the clustering procedure. We compare uncertainty ranges...

... input on the uncertainty varies with the combination of input values used in any given model. It will show that use of the incorrect model through oil and gas zones may give porosity estimates with Monte-Carlo derived uncertainty ranges that exclude the actual porosity. Core data provides the best...
