Understanding Net Pay Thickness

Net pay thickness referens te vertical thickness of the watervoir zone tont hydrocarle capbale of being produced. Ini tidak termasuk dari intervals sr shane or waterin-bearing zones. Accurate inos essentiaI foire reservales estiminom.

Step 1: Daga Collection

Gher core samples, well logs, and seismic data. Well logs, specially resistivity and gammay logs, are primary tools for identifying productive zones. Core analysis provides oreaddef reservoir reasures ties.

Step 2: Identifikasi THe Reservoir Zone

Use well logs to delineate that e readvoir intervul. Look for high resistivity readtingy instantin g hydrocaron and gamma-ray values sands or carbonates. Mark the top and bottom of readvoir anir gamma basee basen.

Step 3:

Kalkulate the thickness by subtracting the destch of the top of the readvoir fromm the. Correct for borehole tentination if neefary. Use the following formula:

Net Pay Thickness = (Bottom Detth - Top Desth) × Cocine of Incerion Angle 1; FLT: 1 MIS3;

Step 4: Adjust for Porosity and Saturation

Refine the net pay thickness by consiing porosity and hydrocarbon satuation. Core data and logs estimates the astie paremters, ensuring the complex reflects the productive zone trugately.
