Oil prices are high, but spending has not caught up—yet. Meanwhile, exploration strategies are changing around the world toward a lower-risk model, and the frenzied pace of US M&A has very much cooled off. -
This case study outlines a full-scale testing program focused on the behavior of thermal casing connections subjected to severe bending and low-cycle fatigue loading. -
With millions of wells having been drilled in the US since the beginning of the oil age, the land is pocked with old, unused wellbores. For most, repurposing is a pipe dream. Plugging is the best option. -
Disposal wells remain the lowest-cost solution for produced water, but concerns over seismicity and long-term sustainability are accelerating interest in alternatives. -
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities. -
This case study presents the first field deployment of acoustic fracturing analysis to evaluate perforation efficiency and implement real-time interventions during pressure pumping.
-
The enrollment trend in petroleum engineering programs continues downward, but a big increase in oil prices has resurrected thoughts of past enrollment booms. -
Pandemic gridlock, rerouting risk, and net-zero expectations are squeezing oilfield service companies into change.
-
Carbonate reservoirs require effective acid stimulation to improve well productivity. For long horizontal wells, a complicating factor has previously been the difficulty of controlling acid placement along the reservoir section. The Smart Liner concept uses a number of small holes spaced in such a way so as to distribute the acid evenly along the reservoir interval.
-
The study assessed the CO2 footprint and NO2 emissions for different drill-cuttings treatment alternatives. The values were then used to create an emissions calculator that can be applied to projects to clarify the actual potential for emissions reduction within the drilling-waste-management process.
-
The Gulf of Mexico explorer is building off its offshore learnings to scoop up early carbon capture and sequestrations projects on the US Gulf Coast.
-
When water and metal meet, you get corrosion. You also get a good dose of creative engineering and innovation.
-
It appears to be possible to sense how fractures change during production using ultrasensitive fiber-optic strain measurements.
-
A rigless chemical frac-hit remediation process was designed to address the damage mechanisms of capillary phase trapping, reduced hydrocarbon relative permeability, paraffin deposition, and minor scale deposition.
-
When it comes to produced water from US shale plays, it’s either recycle and reuse or throw it away—and both are easier said than done.
-
A new dose of constraint may just be the best prescription for those making reserves estimates on prospective unconventional resources.
