Advanced Well Testing & Pressure Transient Analysis
Premium Workshop
For PEA Members Only
This workshop builds the complete advanced well test interpretation workflow in Excel, from raw gauge data through to a defensible reservoir model, with every calculation visible and auditable — no commercial PTA software, no black boxes, no VBA. Day one covers derivative diagnostics built from scratch, wellbore storage and skin decomposition with the damage economics that follow, dual porosity and radial composite systems, hydraulically fractured well behaviour, and proper gas well analysis using real gas pseudo-pressure and deliverability testing. Day two handles the tests that field operations actually produce: variable rates and superposition, boundary effects and the reservoir limit test, DST interpretation, type-curve matching, interference and pulse testing for interwell permeability and anisotropy, step-rate injectivity and fracture pressure, horizontal well flow regimes, and a Solver-driven history match that closes with a hard look at non-uniqueness and test design. The course assumes working knowledge of radial flow, the semilog straight line and the Horner plot — basic drawdown and buildup theory is treated as prior knowledge, not taught — and every topic is worked on a real interpretation problem using field-shaped datasets, with participants leaving holding unlocked workbooks they can re-point at their own wells by pasting one column.
Workshop Objectives
By the end of this workshop, participants will be able to:
Build a Bourdet three-point derivative engine from scratch, including logarithmic resampling, smoothing control and Agarwal equivalent time, and recognise gauge drift and end-of-test artefacts before they corrupt an interpretation
Read the reservoir model off the derivative rather than assuming it, and distinguish dual porosity, radial composite, fractured-well and boundary signatures from one another
Determine wellbore storage coefficient and dimensionless groupings, decompose skin into mechanical, rate-dependent and geometric components, and convert the result into flow efficiency, damage ratio and stimulation payback
Extract storativity ratio and interporosity flow coefficient in naturally fractured reservoirs, and explain why a dual-porosity well can appear to have negative skin
Quantify mobility contrast and distance to a flood front from a radial composite response, and separate a genuine front from a facies change or a damaged zone
Apply square-root and fourth-root-of-time specialised plots to obtain fracture half-length, conductivity and dimensionless conductivity, and compare the effective propped half-length against the frac design
Construct a real gas pseudo-pressure table in Excel using iterative Z-factor and viscosity correlations, and convert a gas buildup into an equivalent liquid problem and back
Analyse four-point and isochronal deliverability tests by both back-pressure and LIT methods, separate true skin from the non-Darcy coefficient, and generate absolute open flow potential and a full gas IPR
Build a superposition time function from an arbitrary rate schedule and recover a usable answer from a test that operations interrupted, choked back or cut short
Identify sealing faults, channels and closed systems from derivative signatures, and convert pseudo-steady-state behaviour into pore volume, drainage area, shape factor and OOIP
Interpret DST pressure records, run validity checks on a short test, and state clearly which reservoir and fluid conclusions a DST supports and which it does not
Match observed pressure and derivative against type curves to extract permeability, skin and storage, and recognise when a visual match misleads
Design and interpret interference and pulse tests, resolve directional permeability and anisotropy orientation from multiple observation wells, and explain why a single well pair cannot give this
Determine formation parting pressure, fracture gradient and a safe maximum injection pressure from a step-rate injectivity test
Analyse horizontal well tests across all three flow regimes to obtain vertical-to-horizontal anisotropy, effective producing length and the split between mechanical and geometric skin
Run a nonlinear Solver regression on permeability, skin, storage and boundary distance simultaneously, demonstrate non-uniqueness with competing parameter sets, and reverse the model to specify shut-in duration, radius of investigation and gauge resolution for a future test
Review and challenge a third-party PTA report using a structured QC checklist

Excel in Production Engineering
Most production engineering calculations don't need expensive software — they need Excel used well. This live 2-hour beginner workshop shows you how to build the core tools of well performance analysis directly in a spreadsheet. You'll create working models for inflow performance, nodal analysis, and decline curves from scratch, using nothing but Microsoft Excel — so you understand what's happening under the hood instead of treating commercial software as a black box.
