Reservoir
As Egypt’s largest oil and gas investor, Eni is ramping up its 2026–2027 drilling campaign with new investments cross the Mediterranean offshore, Nile Delta, Western Desert, and offshore Sinai to strengthen the country’s role as a regional gas and LNG export hub.
This paper presents an experiment investigating dissolution of basaltic primary minerals and conditions favorable for secondary phase formation under deep subsurface storage conditions.
This study aims to investigate the efficacy of chemical additives strontium chloride and barium hydroxide in accelerating CO₂ trapping mechanisms, their effect on dissolution of carbonate-bearing minerals, and resulting poroelastic changes in the host rock.

Tight reservoirs are still in the early stages of becoming a dominant source of energy and economic growth throughout the world for years to come. I recently read two distinctly different articles particularly relevant to tight reservoirs. -
A multidisciplinary approach integrates fracture characteristics, reservoir production, and stress-field evolution to design and optimize the development of unconventional assets.
-
Gas in tight sand and shale exists in underground reservoirs with microdarcy or even nanodarcy permeability ranges; these reservoirs are characterized by small pore throats and crack-like interconnections between pores.
-
This paper sheds light on the nonlinear physics involved in the production of shale-gas reservoirs by improving the understanding of the complex relation between gas production, reservoir properties, and several treatment-design parameters.
-
Unconventional resources are often in good supply, but difficult and expensive to develop. To develop unconventional resources, technologies like hydraulic fracturing and horizontal drilling are key, and higher oil prices will help.

This work presents a workflow that can be used to analyze and forecast time/rate data of wells in low-and ultralow-permeability reservoirs.
-
This paper is intended to increase awareness among the forecasters and the decision makers about pitfalls associated with production forecasting.

The careful planning and successful execution of a multistage-fracture-stimulation completion in one of the first horizontal wells (KZN-F) drilled in the Amin formation in north central Oman instigated a step change in initial production rate and long-term deliverability from this tight-gas-sandstone reservoir. The operator and service company worked as a team, modeli…

The variable data quality of core analysis, the sensitivity of results to different test methods, poor reporting standards, and the reluctance of some vendors to share experience and expertise have contributed to basic mistakes and poor data quality.

When interviewing potential senior-petrophysicist recruits, we exchange pleasantries to break the ice and then I ask an easy, yet fundamental technical question: “How would you explain Archie’s law to an inexperienced colleague?” Then, I sit back in expectation of a slick answer from the candidate. Imagine my surprise when the interviewee takes a sharp intake of breat…
