The world we live in today has been broken into different volumes that can be summed up into data. Production Data Analysis is mostly sought in the handling large volumes of data that is from multiple sources, contains multiple frequency records or in events where identification and synchronization are required. It is also used to assign appropriate production rate to the right fields. The article below highlights some of the benefits associated with records analysis in the world today.
Analysis can be separated into two and that is the estimation of reservoir properties from transient flow data and the estimation of reservoir volume from boundary-dominated flow information. It is important to note that legacy creation information may not contain the quality nor the frequency sufficient to produce competent estimates of reservoir properties. When dataset is complete then it is of good quality.
Using production figures investigation is effective and has reason within it as it consists reasonable reservoir characteristic, it however has its fair share of disadvantages such as that it does not entail an integrative technique that can accommodate results from many individual wells and does not have a process wellhead and bottom hole pressure figures in mature fields.
If the tubing and casing pressure separate it could be due to liquid load-up or a leak in the tubes. Scatter in creation rates and flowing pressures could mean unstable flow. Flowing pressure with large-duration step changes indicate infrequent measurements thus comparison with flowrate information is crucial to ensure that the pressure information are competent. Deconvolution issue works around poor quality of information.
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.
History Matching HM is also a method that is used in creation information breakdown and it is described by using the results of TCM which are area drainage, assumed parameters and bottom hole pressure as a starting point. This is because HM does not include any unique solutions hence using the already known parameters saves on time and there is a high probability for a better match.
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.
