In Rdca: DCA Tools for Decline Rate Analysis and EUR Forecast
Rdca
Rdca is a Decline Curve Analysis (DCA) package for oil and gas
reservoirs. It generates a table of rate, cumulative, nominal decline
rate, and derivative of loss-ratio over time in a data frame format. It
also provides an optimization tool to fit a DCA model on production
data. The package currently supports Arps ‘exponential’, ‘harmonic’,
‘hyperbolic’, and ‘modified_hyperbolic’ models.
Installation
You can install the released version of Rdca from
CRAN with:
install.packages("Rdca")
