HyperbolicDeclineCumulative
Calculates cumulative production using Arps (1945) hyperbolic decline curve, [L3]. Units of volume [L3] and time [T] must be consistent.
HyperbolicDeclineEUR
Estimated Ultimate Recovery (EUR) to an economic rate limit for Arps hyperbolic decline, [L3]. Returns cumulative production up to the time the rate reaches the economic limit.

HyperbolicDeclineRate
Calculates rate using Arps (1945) hyperbolic decline curve, [L3/T]. Units of volume [L3] and time [T] must be consistent.
HyperbolicDeclineTime
Time to reach an economic rate limit for Arps hyperbolic decline, [T]. Returns the time when the production rate falls to the specified economic limit.
