The Griffith 11 #1 well located in Desoto Parish, Louisiana was completed and brought online in January 2009. The exact reading for total gas produced from the Haynesville shale and shipped to market through March 10, 2009 is reported at 568,856 MCF or .568 BCF.
The yellow diamond well on slide 16 in Desoto Ph is Griffith 11. How do you interpret this slide for Griffith 11. What is Average Interval Log Porosity Feet vs. Average Interval Log Sw? I have been told that Griffith has 173' of HA.
Next, look at slide 17. What does Phi H mean? Clearly, Griffith is off the charts relative to the other wells! Also, I think Net/Gross is understandible, but correct me if I am wrong that it is the net pay thickness to the gross thickness. Here Adcock is off the charts at 90%, but Griffith 11 is second at 70%.
Now can you tie the three charts together for me. If Griffith 11 has 173' of HA. thickness, is it 70%, or 121', of net pay? Then what does Average Interval Log Porosity and Phi H mean?
WR, the Griffith 11 likely had 173' of net HS thickness so the gross thickness would have been ~ 247'. Porosity-Feet (Phi H) should just be thickness times the average porosity but I am not sure if the calculation is based on the gross interval or just the net pay. I would assume Sw represents the water saturation %.
My primary take-away is the Haynesville Shale interval thickens to the north but the net/gross and porosity decrease which lowers the initial flow rate. This may require a different completion technique for wells on the northern edge. The Southern Star wells look good since their Phi-H is comparable to wells with good initial rates.
