... was evaluated by recording production data from unsteady-state coreflood experiments. The injection of the chemical with equilibrated gas resulted in condensate saturation to decrease from 19.6% to 6.5%. This decrease was not instantaneous and took some time to occur indicating that the chemical needs time...

... work has shown that Swanson's Mean, which relates the Reserves categories through a cdf of a normal distribution, is an inaccurate method to determine the relationship of the Reserves categories with asymmetric distributions. Production data are lognormally distributed, regardless of basin type, thus...

... For evaluating the developed AI framework we developed a synthetic reservoir box model ( Figure 2 ) in order to retrieve the injection and production data over a time horizon of 4.5 years. The reservoir is inclined, and has four injector wells in the central part of the reservoir and four producer wells...

... perspective, it is helpful to monitor and analyze the recorded production data (e.g., pressures and rates) to infer the strength of communication between sibling-sibling and/or parent-child wells using rate- and pressure-transient analysis methods. Therefore, the objective of this study is to develop...

The data visualization software, Spotfire, was used to achieve the data visualization guide which focuses on Gas Utilization Factor (GUF): gross liquid production (bbls/day...

This method applies a log-log plot of rate versus time combined with a log-log plot of rate versus material balance time (MBT). In addition to log-log plots...

Finally, we used cutoff coefficients to further reduce hydraulic fracture geometries to match production data. The results of this work showed a fast and flexible method to estimate...

... long periods of time with a stable reservoir pressure and constant flow-rate conditions. Conversely, the long duration and high frequency of well production data have high value for detecting connectivity if noise, abrupt changes in flow-rate and missing data are dealt with. In this work, a methodology...

... commercial software and verified its applicability by analyzing the flowback and long-term production data from a field example in Eagle Ford shale. The validation results confirm that our method can closely calculate water and oil influx from matrix as well as the average pressure and saturation in the HF...

... Abstract This paper presents three sets of new integrative production decline type curves for the analysis of horizontal well production data in order to systematically estimate reservoir flowing capacity ( kh ), effective horizontal wellbore length and original oil/gas in place. In addition...

Understanding multiphase flow regimes is the first step for selecting proper relative permeability curves and developing representative multiphase rate-transient models. Another objective of this paper is to investigate the harmonic decline (HD) behavior of water...

Total Fluid Logs are utilized to 1) constrain interpreted fracture heights, and 2) work in combination with pressure and production data for Rate Transient Analysis (RTA) for significantly improved estimation of the half...

.... The constructed PVT models are used as input to dual-porosity dual-permeability (DP-DK) models, which are calibrated using multi-phase production data. The results further indicate that the two EOSs could predict an optimal HnP process with a minimal recovery difference. A new fluid modelling workflow...

In this study, a deep learning approach is developed to predict the long-term well performance based on a moderate duration of production data. A data-driven procedure was implemented...

A key implication of this work is that collecting new information (i.e. new well production data) does not always narrow the uncertainty band for type well EUR. The EUR uncertainty band depends not only on the number of wells with production data...
