negative OIIP result from MBE

dear Chee Hoh Peh

I really appeciate your help regarding my question.
I'll check my pressure data with your comment & reference book.

I've another question calculating averaged reservoir pressure in multi-wells reservoir(All wells have a communication each other.)
I heard about the method, volume averaged pressure,
but each well production start time is different, so cumulative productions were also different.
Would you recommend me any reference books or ducuments for calculating averaged reservoir pressure, once more??

regards,
sharpjiy

Dear Sharpjiy,

See Dake - "The Practice of Reservoir Engineering", he has excellent worked examples and discusses in depth how to average reservoir pressure.

Your reservoir pressure is an average of well SIBHP, usually obtained by PTA.

Do not worry about well timing, what you need is average reservoir pressure and total fluids (gas/oil/water) produced at each average reservoir pressure point.

Take a look at this paper

Also this one is good

Dear Shakespear

Thank you for your help, shakespear.
The documents you recommended were really helpful for me.
And, I was also impressed your last comment, petroleum should be used as a meterial not as a fuel.
I totally agree with you.

Dear Chee Koh Peh

Thank you for your answer, Mr. Chee.

When I was a student, I just run how to calculate reserve with MBE, or volumetric, decline curves.

But in real works, the problem was how to set input data for reserve estimation.

Calculation itself was conducted many software or other tools.

Your comments and references would be great help for me.

thank you.
