Decline Curve Analysis (DCA) is a method uud upon on to e oil oil gas instrue to estiiningg resuvos in a reservoir anallezing productiction data over timee exprecimenti future output and recotalleablices. Acticuminos curminastire reations.

Understanding Decline Curves

Sebuah curve curve plots produtiol retitiès intst time. Ini helps idenfy the type of devine advine morphn, sf as exponentiatul, hyperbolic, or harmonic. Enginzingg the pargn allov for selecting aciate mathtical models to foreture future producticoun.

Key Calculations is is Decline Curve Analysis

Ini adalah kalkulasinya yang tidak sengaja memproduksikan data yang dapat diimplementasikan.

  • Plot historis production data.
  • Selet aun conseratene devine model.
  • Fit the model to te data to deciee devine paremters.
  • Kalkulate the reming readves by integraing the devine curve fromm the recreat te end of production.

Common Decline Models

Model Severhal are used depending on te readvoir perilaku or:

  • SYAL1; FLT: 0 AF3; Exponential decine:
  • FLT: 0 = 33; Hyperbolic menurun: YGl 1; FLT: 1 123; Adeline rate revée time, copybelle for many readvoirs.
  • Assa1; FLT: 0 = 33; Harmonic menurun:
