Decline curve analysis
Hello members i have question
General equation of decline curve is qt=qi/(1+bDit)1/b
So when the decline is exponential then b=0 ...my question is how the equation is going to be qt=qi exp-dt
When i subsitute b=0 i dont get the above equation!

Dear Dhiaa12,
You could not substitute that.
You can refer to folow file.
Best regards
Truong

Thanx Truong,,
I spent many times to answer look into this quiz.

Re: Decline curve analysis
Dear Fanarco & Dhiaa 12,
Production Analysis is topic in my honours project and my thesis. I have researched some methods in PA such as: DCA, Fetkovich, Agarwal - Gardner, Blasingame, Flowing Material Balance.
If anyone have questions about PA feel free to ask. I really would like to share my experience about that. I am not sure I can answer right, but we can discuss each other more and more.
I am sorry, my English not well
Thank you and best regards,

What is "Flowing Material Balance"
Re: Decline curve analysis
does anybody has decline curve analysis in spreadsheet.it will be useful to many reservoir engineers.
I am interested in modified decline curve analysis

Re: Decline curve analysis
sorry it should be modified hyperbolic decline analysis

Re: Decline curve analysis
exponential decline gives conservative figure of reserves whereas hyperbolic gives reserves on higher side.Modified hyperbolic is in between two and nearer to realistic reserve estimates.There are software/programs,spreadsheet for modified hyperbolic decline curve analysis.I am looking for one

Re: Decline curve analysis
Just provide me with the equation then i can create the sheet for you
Re: Decline curve analysis
fanarco can you give me you your private e-mail as i am unable to attach excel file.In modified hyperbolic decline curve analysis we calculate Di,Dlim and b

Re: Decline curve analysis
Hello,
Could someone share how can we calculate Dlim, the decline rate at which the modrel switches from Hyperbolic to Exponential model.
I need sort of equation that can predict (estimate) Dlim.
Thank you!
