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.

After a drop in drilling activity in recent years, the Haynesville shale has become a hot area for natural gas production in the US, and companies are looking to bolster their positions in the area. -
The complete paper discusses the advancements in mud-displacement simulation that overcome the limitations of the previous-generation simulator and provide a more-realistic simulation in highly deviated and horizontal wells.
-
Natural gas producers should remain happy campers for the foreseeable future; they are supplying an increasing long-term demand at an increasingly stable international market price.
-
The primary objective of this study is to address all known causes of productivity declines in unconventional shale gas formations with horizontal multifractured wells and to develop a fully coupled geomechanical/flow simulation model to simulate these production conditions.
-
The promise of getting 30% more oil production from shale wells has set off a race by companies trying to see if they can replicate what EOG has done. But the big question is: Can it add enough oil to increase the industry’s low average recovery rate?
-
Currently, there are few studies on smart waterflooding in tight and very tight oil reservoirs. This work examines smart-waterflood opportunities in such reservoirs.
-
Previous studies demonstrate that Montney rock samples present a dual-wettability pore network. Recovery of the oil retained in the small hydrophobic pores is uniquely challenging.
-
While enhancing oil production from multizone, hydraulically fractured completions in tight reservoirs is not straightforward, recent studies have shown that applications such as gas injection and waterflooding have the potential to create significant improvement in oil recovery.
-
This paper presents the performance results from one of the waterflood pilots in the Viewfield Bakken.

Schlumberger’s new multifunction spectroscopy system builds on previous innovations to offer the first complete cased-hole formation evaluation and reservoir saturation monitoring capability that provides openhole-equivalent logging measurements.
