Notes from the reservoir.
Long-form articles on matrix acidizing, EOR screening, hydraulic fracturing, scale management, cementing, reservoir analogues and AI for reservoir engineering.
Matrix Acidizing: The Complete Engineering Guide (2026)
A practitioner's reference for designing matrix acidizing treatments — from candidate screening to post-job skin evaluation — with the physics that actually matter.
EOR Screening: A Modern Decision Framework for Mature Assets
1980s screening tables miss field-specific physics and ignore commercial reality. Here's a defensible framework that doesn't.
Hydraulic Fracturing Design Fundamentals That Still Decide the Job
Most screenouts and underperforming stages trace back to a small number of inputs. Get them right before tweaking schedule.
Downhole Scale Management: From Water Analysis to Squeeze Design
Scale management starts with a defensible water analysis and ends with a return-curve you can audit. Everything in between is engineering.
Primary Cementing Displacement Efficiency in Deviated Wells
Channeling on the low side of a deviated well is rarely a slurry problem. It's a displacement problem you can simulate before you pump.
Using an Analogue Field Database for Faster Reservoir Decisions
When the model is uncertain and the data is thin, the strongest argument is a comparable field that already lived the answer.
Wormhole Propagation in Carbonate Acidizing: What Engineers Should Model
The optimal-rate curve isn't a constant. Heterogeneity, temperature and mineralogy shift it — and shift the right pumping schedule with it.
Polymer Flooding Screening: When It Works, When It Doesn't
Polymer projects fail more often on field operations than reservoir physics. Screen for both — early.
Sandstone Acidizing Fluid Selection: HF/HCl, Mud Acid and Retarded Systems
Picking the right acid system in sandstones is mineralogy first, temperature second, and rules-of-thumb a distant third.
CO₂ EOR Screening Checklist: Miscibility, Sources and Surface Constraints
CO₂ EOR is as much a logistics decision as a reservoir decision. Both belong in the screening table.
Acid Diversion Strategies for Long, Layered and Deviated Wells
Coverage, not just chemistry, decides acidizing outcomes. Here is how to choose and sequence diversion across long or layered intervals.
Acid Fracturing vs Hydraulic Fracturing: Choosing the Right Treatment
In the right carbonate, acid fracturing wins on conductivity per dollar. In the wrong one, it wastes the job. Here's the call.
