There are many challenges that one might encounter in Production Data Analysis. Here is a sample of some of the common challenges which occur during analysis including pressure, flow rate, well completion and General. These issues must be recognized if not addressed in the case that a product examination sequence is conducted. Influence of data examination could vary from high, moderate to very high. The article under forth describes of the factors generated and importance of data examination.
This type of records analysis is one that researchers can depend on to give them the best results when dealing with mature fields. In creation information study, practical methods have been the ones that have become dominant and they are categorized into two being Decline Curve study DCA which does not entail reservoir characteristics and Type Curve Matching which is subjective.
Accurate and frequent estimates of rate and pressure information are considered to be a necessity. If the flow rate suddenly increases or decreases, then the pressure should decrease and increase respectively if not then the flow rate and pressure information are inconsistent or uncorrelated. This could mean that flow is taking a different path, flow pressure is measured in the wrong direction or a liquid is loading.
Decline Curve study is one of the methods used and it used as a temporary benchmark for estimating b. Those employing this method already know it is a mathematical technique used to forecast performance and it does not entail any physical basis. TCM uses a set of curves generated based on the value of b that was obtained from Decline Curve study.
It is a reliable technique as it also employs other methods like history matching to try and increase its accuracy of estimation and interpretation of figures. History matching is quite a challenging method and is not as straightforward as it may seem as it is solely based on facts. However when type curve investigation is used them the results acquired through history matching are not used.
In the context of creation information investigation deconvolution will be used only as a B - spline diagnostic method to identify inconsistencies in the pressure information. It does not allow estimation of rates thus the given rates are assumed to be correct. If plot shows major variations, then the information is inconsistent despite measured flowrates and pressure being incorrect. Comparison of raw and history figures is crucial.
Diagnostic plot implies that a certain feature will emerge from a given figures profile. The goal is to provide a broad spectrum of diagnostic insight of the plots. If significant information mismatch were to exit, then we would conclude that these creation figures are not correlated or possibly corrupted. Comparison of measured pressures and those pressures computed from deconvolution show only fair agreement.
When records has been collected and analyzed accurately, then it should be able to set grounds of accurately measured creation rate and the pressure records should produce vigorous and competent interpretation results that are comparable to estimates from analyzed transient records also an overall HM model must be presented to help compare the raw rate and pressure data.
