Agile Geoscience blog reading for the uninitiated. These links will fast track and kickstart AAPG [Imperial Barrel Award] (IBA) contestants and exploration teams.

Useful things

Basic cheatsheet

Geophysics cheatsheet

Rock Physics cheatsheet

Petrophysics cheatsheet

Petroleum cheatsheet

Practical things

The Agile Interpreter's Canon — a list of strategy and guidelines for seismic interpretation.

How to create your own time scale — build and editable and fit-for-purpose stratigraphic column.

How to make a stratigraphic column — build and editable and fit-for-purpose stratigraphic column.

Visual crossplotting — use color spaces for multiple attributes and co-located images for dramatic comparisons and maps.

How to cheat at spot the difference — take the hard work out of visual inspection.

The integration gap — a graphical representation of empirical and disciplinary silos in the subsurface.

Wherefore art thou, expert? — long live the unvested generalist!

How to cheat — using the rock physics cheatsheet.

Software and images you might need

Geophysics apps FTW — calculators and geoscience applications for Android.

Volumetrics on the back of a digital envelope — volume* Android app.

Building tune — building and Android app for studying thin bed resolution and tuning.

Tuning geology — wedge models for bed thickness and determining seismic tuning effects.

Reuse and recycle — awesome graphics from Matt Hall's petroleum geology course. Yours to augment and build on!

Polarity cartoons — what is a peak and what is a trough? Every seismic display should have not only a colorbar in the legend, but also the polarity displayed. Don't leave your audience guessing.

How big is that volume? — Wolfram Alpha widget for computing the disk size of seismic data.

How to choose an image format — pick the right image format for the job.

When to use vectors not rasters — difference between vector graphics and raster images.

Geophysics terminology

A is for amplitude - the first and foremost of seismic attributes.

B is for bit depth - know the difference between resolution and precision in this great example.

C is for clipping — understanding data ranges and the losses in clipping.

D is for domain — back an forth between the seismic dimensions, and the earth's three spatial dimensions.

E is for envelope — a seismic trace attribute

E is for envelope 2 — a seismic trace attribute with real example

F is for frequency — definition of frequency and it's expression in common geophysics signals.

G is for gather — acquisition and processing jargon

H is for horizon — an overly mis-used and abused jargon word.

I is for integrated trace — another seismic attribute. Kind of like a quick and dirty relative impedance inversion.

M is for migration - the process of refining the focus of a seismic image. With great diagrams and gotchas.

O is for offset - Both a parameter and a dimension used a throughout seismic data processing.

Concepts you need to know

What is a Darcy? — Build your intuition with this permeability example

What is shale? — definition

What is AVO? — introduction to the AVO effect.

What do you mean by average? — be specific about how you do basic statistics

Location, location, location — information you need to properly locate a point on the earth.

Rocks, pores, and fluids — The basics of formation evaluation, and the so-called Triple Combo.

The effective medium — The whole is not attained by the disparate measurement of it's parts.


Philosophy and intuition builders

Confirmation — bias in geoscience

Confounded paradox

Must read geophysics — three papers that will change the way you think.

Will this change anything? — a message to consider with every endeavor

Smaller than they look — numbers, figures, and phenomena outside our normal levels of comprehension

Reliable predictions of unlikely geology — Bayesian statistics with nice examples.

Shooting in the dark — precision, accuracy, reproducibility are all measures of uncertainty.

Four days of oil — an example that will stick. On how much the world consumes in a four day period.

Innovations of the decade — great achievements in that last decade.

Innovations of the decade to come – what we might expect.

Measuring value — how does your professional work affect the bottom line?

More than a blueprint — seeing is believing, but in the case of the subsurface, seeing can be misleading.

The power of stack — concept of increasing signal to noise raio.

Species identification for the rock kingdom - empirical taxonomy.

Bring it into time — the travel time domain

On brevity — effective in writing, presenting and working.

What is unconventional? — definitions of the buzzword.

Shale vs tight — our most clicked blog post.

Great geophysicists #3 — dispersion phenomena.

The scales of geoscience — graphic of spatial scales of earth processes.

Seeing red – some aspects of what makes an effective figure.

Pair picking — a plea for working as a tag-team of interpreters.

Are you a poet or a mathematician? — words of estimative probability

McKelvey's reserves and resources — improved graphic that battles against ambiguity in communication.

Please sir may I have some seismic petrophysics? — what petrophysics needs to offer geophysicists and seismic interpreters.
