Flow Regime Identification With Filtrate Contamination Monitoring

摘要

Implementations of the present disclosure relate to apparatuses, systems, and methods for determining when a well cleanup process has established developed flow and then extrapolating out modeled fluid parameter values to determine parameter values for a formation fluid. The model fluid parameter values may be modeled using a power law function having a specified exponent value.

1. A method for extrapolating a formation fluid parameter in a reservoir, the method comprising:
obtaining a measured data array including at least a sample fluid parameter and a durational value; fitting a model to the measured data array, the model being defined by a power law function containing the durational value; extrapolating the model according to the power law function when the durational value equals infinity to find a formation fluid parameter; determining a fitting interval start point; and confirming the fitting interval start point overlays a linear portion of the measured data array when compared on log-log scales.
