Oil & Gas Well Testing & Fracking

Compare old days drill-stem tests with modern practice in North Africa’s tight gas and tight oil reservoirs, noting Ordovician and Devonian formations and back-pressure strategies in 1958–1964 and 1986 tests.

Analyze the 1986 well test data set with short flow durations, tracing phases from initial hydrostatic pressure and packer setting to brief preopening, build-ups, drawdowns, and final pressure after removal.

An archaeology of decades of dst data reconstructs the real alpha-5 profile, showing initial hydrostatic pressure, packer isolation, drawdown, build-up, and convergence toward the reservoir virgin pressure.

Examine hydraulic fracturing in an analogue field and its limits for the main field. Note Ordovician formations are tighter than Devonian, with Ordovician Gray porosity 6–9% and permeability around 0.01.

Analyzes processed well data to distinguish skin effects from fluid and completion factors, and compares Alpha and track field drawdown drivers like nutcake and retrograde condensation.

Evaluate the relevance of analogies using three axes: geology, fluid composition, and operations, and show why the field is not a good analog for driving fracking in the Alpha field.
