Integrated Formation Evaluation
Premium Workshop
For PEA Members Only
Formation evaluation is where the reservoir first becomes measurable. Every downstream calculation, net pay, porosity, saturation, in-place volumes and ultimately the development plan, rests on how well the logging data was acquired, corrected and interpreted, and on how consistently it was tied back to core and pressure measurements.
This workshop covers the full integrated formation evaluation workflow. It begins with data preparation: log quality control, depth matching and normalisation, and an understanding of what each logging measurement actually responds to, its depth of investigation and its vertical resolution. Participants then work through lithology and porosity evaluation in both clean and shaly formations, resistivity measurements and their environmental corrections, and the application of the Archie equation together with the parameters derived from electrical measurements on core.
The workshop then moves into saturation-height modeling and the integration of core, log and capillary pressure data into a consistent petrophysical model. Pressure and fluid data from wireline formation testers is covered in detail, including quality control of pressure measurements, gradient analysis, fluid contact determination and the use of fluid sampling results.
The final sections address advanced measurements and their applications: nuclear magnetic resonance logs for porosity partitioning and permeability estimation, cement evaluation logs, and quick-look log analysis for real-time operational decisions. The workshop closes with integrated interpretation, bringing petrophysical, engineering and geological data together into a single reservoir description.
The workshop is delivered at an intermediate level and is intended for petrophysicists, reservoir engineers, geologists and operations engineers who work with well log data.

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.
