Friends, I am wondering how do one determine net pay in shale gas reservoirs? I am new to this forum. Response appreciated. -Tamar |

Hello Tamar, Likewise I am having problems calculating an Net Pay/Sw/Porosity/Drainage Area/Recovery Factors for a fractured oil shale in the Second White Specks formation. What is the most appropriate way to estimate volumetrics on a shale gas/oil zone? Some troubling issues I was having is how much is the true porosity and how much is effective? Deep resistivity is fairly low on the logs. Yet this wells initial production is 100 barrels/day. The true porosity from neutron/density is somewhere around 30%. I'm assuming a quarter mile drainage area. The logs are reading high gamma ray (spectral gamma ray shows high amounts of Uranium and Thorium). Resistivity micro-imaging tools have been ran as well. Also, what wireline tools work best in identifying shale fractures in your opinion? Thanks and welcome to the forums! |

Been a way for a while... and luckily sort of found a work around/best solution to the problem. Too complex to post here though. I guess we could use some of the imaging tools to identify the fractures... Haven't applied it yet though. |
