A forward thinking expert system in well test analysis
<p>"Identifying reservoir parameters through well test analysis requires the use of numerous heuristic rules, such as establishing the initial data (time prior to test, flowrates, etc.) and selecting the type of analysis (multiphase, multirate, fracture, etc.), to evaluating the correct data for …

Machine learning for well rate estimation : integrated imputation and stacked ensemble modeling
… supervised machine learning problem for well rate estimations utilizing well test features that are far from independent and identically distributed (IID), and exhibit missing data with a not missing at random (MNAR) classification from three different oil fields. This research introduces …

Analytical solutions of pressure-production tests with permanent multisensors in oil gas and water zones
… for improving the monitoring methods for wells. These wells may have up to eight pressure sensors, recording infrastructure, and data transmission. The information from the sensors is at the disposal of the analyst immediately after the measurements are performed to make decisions about …

Exploring wellbore and reservoir temperature profiles in fluid circulation and production operations
<p>"The wellbore heat flow occurs during different well operations resulting from any temperature differences between the wellbore fluid and the adjacent formation. Understanding the direction and mechanism of heat flow whether it is conduction or convection help to represent this heat exchange …

Uncertainty reduction in reservoir parameters prediction from multiscale data using machine learning in deep offshore reservoirs.
… measured, are available only at small number of well locations. The limited data are then combined with geological interpretation to generate a model. Also increasing the degree of this uncertainty is the fact that the reservoir properties from different data sources - like well logs, cores and …

Accurate Cylindrical-Coordinate Numerical Models For The Analysis Of Hydrologic Tests
Analytical solutions to well hydraulic problems have restrictive assumptions that often do not match real world conditions. Although numerical models more closely match reality, they either ran too slowly to be practical or lacked accuracy because of coarse grid spacing and large time steps. …
