Simple shortcuts to day-to-day petrophysics.

Got a shale gas reservoir? Evaluate these four parameters and you are good to go.

When you evaluate a shale gas reservoir, you need to think about four things: Kerogen contents Kerogen is one the key properties in shale gas evaluation. Kerogen relates to TOC, absorbed gas, porosity and gas saturation. Most unconventional reservoirs like shale oil and shale gas contains...

Do You Need Kerogen Correction In Resistivity For Shale Oil/Shale Gas Evaluation?

When kerogen and shales are present, you must apply a shale and kerogen correction to get effective porosity. While we can correct for shale effect in resistivity, do we need to worry about making kerogen correction for resistivity and water saturation? Is there a kerogen correction we must...

11 different ways to integrate your NMR data with your open hole logs. It's not all about T2!

T2 is the building block of NMR log. Having the wrong T2 leads to inaccurate bound water, effective porosity, and permeability. However, the T2 cutoff is not the only thing that matters in NMR. There's so much thing you can do to integrate an NMR data set with your open hole logs. Provided that...

Your density log doesn't actually measure porosity.

I like to watch MTV's Catfish Show. The show tells the tale of desperate online daters trying to track down their internet crush. In most episodes, the actual people behind these fake profiles turned out very different people. Which brings to my point today. People say that a density log...

Wireline Logging In An Ultra-Deep Well: The Why, The What and The How.

How do you run a well log for an ultra-deep well? What are the things to consider and how to do you tackle them? Don't get confused. Ultra-deep doesn't mean deepwater, but you could log an ultra-deep well in a deepwater environment. Now, let's assume that you need to log a 28,000 ft long...
