Learning Paths
50 guided paths across the OgbonLab library: each one a sequenced route through the interactive textbooks toward a working capability, with a placement quiz, spaced practice, and widget challenges for the applied steps.
Seismic Methods
The seismic experiment, end to end: acquire, process, image, interpret.
Become a 3D Seismic Interpreter
From your first cube to a defended prospect. The craft of seeing geology in seismic: picking, structure, stratigraphy, and the attributes that make subtle.
Faults, Fractures, and Structure
Structure is the first thing a prospect has and the last thing a model forgives.
Seismic Stratigraphy and Facies
The interpreter reads geometries; the modeler fills a grid. This path walks the whole distance between them: terminations and sequences on the section,.
Design a Seismic Survey
Fold, offset, azimuth, and the judgment to trade them. From the physics of sources and receivers to a geometry you can defend, on land or at sea, with the.
The Well Tie: From Log to Seismic
The workflow every subsurface team runs and few can defend end to end: velocity from the sonic, a wavelet with its phase pinned down, a synthetic built from.
Noise and Multiple Attenuation
Most of a processing project is spent removing energy nobody ordered.
Depth Imaging and Velocity Model Building
Structural truth in depth is earned, not rendered. You estimate velocity from the data itself, compute the traveltimes migration runs on, choose an.
Velocity: One Number, Five Sciences
The sonic measures it over centimeters, semblance picks it over kilometers, rock physics explains it, tomography and FWI refine it, and pore-pressure.
The Salt Problem
Salt giveth and salt taketh away: it builds the traps that hold supergiant fields, then wraps them in a 4.5-kilometer-per-second refracting blanket that.
Prepare for Full-Waveform Inversion
The physics, the adjoints, and the judgment FWI actually demands.
The Resolution Wars
Every survey is a fight for resolution and the earth fights back: wavelength sets the floor, tuning blurs thin beds into amplitude, aliasing punishes coarse.
Model the Seismic Response
Type the earth in, get the seismic out. Wavelets, convolution, and the full wave equation, ending in a modeling lab where you build the model and simulate.
Seismic Attributes: The Interpreter's Toolkit
The attribute menu in every workstation is long, and most of it goes unread.
Quantitative Interpretation: Rocks from Seismic
From amplitude to pore fluid, with the error bars attached. Rock physics, AVO, inversion, and the calibrated probabilities that let a seismic volume speak.
Anisotropy and Fractures
Rock has grain: shales are faster along the bedding, fractured carbonates faster along the cracks.
When the Earth Lies: An Atlas of Pitfalls
Every dry hole was drilled on data that looked convincing. This path collects the classic deceptions, fizz water posing as gas, cemented sand posing as pay,.
Listen Without a Source
Every survey in the rest of the library begins by making a bang. This one never does.
Time-Lapse: Monitor a Producing Field
The reservoir moves; learn to watch it. Rock physics of change, acquisition built for repeatability, processing that protects the difference, and the case.
Petrophysics & Reservoir
From the wellbore to the flowing field: logs, volumes, models, storage.
Read the Well: Petrophysics
From a raw log display to barrels with error bars. Porosity, saturation, permeability, and the judgment calls between, worked on one honest well from first.
Advanced Formation Evaluation
Read the Well taught you to sign a saturation; this tier is for the wells that fight back.
Porosity: The Space Between
Nothing on earth is worth more per cubic meter than properly counted emptiness.
The Life of a Sand
Follow one sand from the river that dropped it to the reflection that found it.
Shale Runs Everything
Most of the sedimentary column is shale, and it plays every part in the play: seal over the trap, source rock in the kitchen, clay that sabotages the.
Water: The Other Fluid
The reservoir was full of water before anything else arrived, and it will be full of water again at the end.
The Carbonate Problem
Sandstone rules are so convenient that half the industry forgets they are local bylaws.
Prospect Evaluation and Volumetrics
A prospect is a closed contour until you can defend the barrels inside it.
Pore Pressure and Geomechanics
Pressure is the one measurement that reads the connected fluid system instead of the rock at the wellbore, and it is also the load the rock itself is.
Keep the Well Open
A borehole is a hole punched into a loaded rock, and whether it stays open is a stress problem.
Build the Reservoir Model
Data to grid to barrels to forecast. The static-to-dynamic workflow end to end: framework, facies, properties, volumes, upscaling, flow, and the history.
Simulate the Reservoir: Flow, History Matching, Forecasting
The static model is a photograph; the simulator makes it move.
Unlock Tight Rock
Nanodarcy rock holds decades of gas and will not give up a molecule on its own.
Geostatistics for Reservoir Characterization
From spatial data hygiene to kriging, simulation, and a full reservoir capstone. The statistical spine of every property model you will ever build or QC.
Store Carbon Underground: CCS from Site to Certainty
Storage is the petroleum system run in reverse: instead of finding what a trap kept, you must prove what it will keep.
One Well, Five Sciences
Ogbon-1 is one borehole through one reservoir, and five disciplines each claim a piece of it.
Computational & Data
Statistics, machine learning, and working code for working scientists.
Statistics for Researchers
The statistics your reviewers assume you know. Probability, estimation, honest testing, calibrated intervals, regression, and causal inference, built for.
Bayesian Inference in Practice
The machinery of belief under evidence. You learn what an interval actually promises, then build posteriors and earn them: conjugate updates, Gibbs and.
Uncertainty by Simulation
Sampling as a way of knowing. MCMC, the bootstrap, and posterior checks, then straight to the subsurface: realisations, probabilistic facies, and Bayesian.
Regression in Practice: GLMs and Beyond
Most researchers run regressions they could not defend under questioning: a line fit by habit, diagnostics skipped, a logistic bolted on when the outcome.
Machine Learning for Geoscientists
Models that respect the geology and the test set. From problem framing and gradient descent through the classical toolkit to CNNs, with the honesty.
Python and Data Pipelines for Geoscientists
The nine-tenths of every data project that is not the model: getting earth data into Python, described honestly, engineered into features, and flowing.
Machine Learning in Seismic Practice
Not a demo reel. Where learned methods actually ship across the seismic value chain: compressed sensing and deblending in acquisition, denoising and.
Deep Learning for Wave Physics
From a single neuron to a PINN that converges, with every failure mode met on purpose.
Learned Solvers and Synthetic Wavefields
Networks that make wavefields. Forward modeling as data generation, eikonal nets, DeepONets and Fourier neural operators, and generative velocity priors:.
Mathematics
The mathematics underneath, read properly.
Precalculus Foundations: Algebra and Geometry
The algebra and geometry that calculus quietly assumes: numbers built up carefully from the integers, equations solved and defended, the plane measured with.
The Mathematics Behind Seismic Processing
From the algebra you half remember to the transforms processing leans on.
Mathematical Methods for Geophysics
The graduate mathematics your methods quietly assume, built properly once: several variables, the integral theorems, holomorphic functions, Fourier, and the.
Linear Algebra for Machine Learning
Machine learning is linear algebra in production. Build vectors, systems, matrices, and determinants from first principles, take the working toolkit of.
The Shape of Space: Geometry and Topology
The geometry mathematicians actually study, read in order: open sets and what they buy you, the single theorem that swallows the integral theorems of.
Infinity, Structure, and Computation
What pure mathematicians actually study, in one traverse: primes and modular arithmetic, the sizes of infinity, the foundations that nearly cracked, the.
Read and Write Mathematical Proofs
The skill that turns mathematics from spectator sport to craft.
