The global energy system is in transition. As renewable penetration rises, the challenge of balancing intermittent supply with fluctuating demand becomes ever more pressing. Industrial-scale energy storage will be the backbone of a resilient low-carbon grid. Yet, with multiple competing technologies—each with strengths and limitations—the question is not whether to store energy, but how. Below, I review the… Continue reading Industrial-Scale Energy Storage

CCS Storage Site Risks
This article is based on the paper “Workflows and Considerations for CO2 Injection in a Highly Depleted Gas Field” which was originally presented at the Offshore Mediterranean Conference in 2011. As the world intensifies efforts to reduce greenhouse gas emissions, Carbon Capture and Storage (CCS) has emerged as a critical technology. CCS involves capturing CO₂… Continue reading CCS Storage Site Risks
Determination of Rock Properties from Logs I
UNCONFINED COMPRESSIVE STRENGTH The production of sand from hydrocarbon reservoirs can result in various operational and safety issues. In addition to lost production from sand fill and or plugging, solids particles can cause significant erosion to both downhole tubulars and surface facilities. Predicting the onset of sand production has always been a bit of a… Continue reading Determination of Rock Properties from Logs I

A simplified workflow for completion tubing metallurgy selection
We’re all familiar with the sort of H2S and CO2 partial pressure material selection graph shown in Figure 1. Here, the appropriate metallurgy for a well based on the partial pressure of the CO2 and H2S as well as operational temperature is divided into zones. Increasing CO2 pushes us up the Y-axis moving from standard… Continue reading A simplified workflow for completion tubing metallurgy selection
