Parent well modelling

This article highlights some of the considerations that should be made when evaluating the well completion strategy with focus on two unconventional plays, the Bakken and the Eagle Ford.

Keeping complexity under control

Nicole Ramsey Braley, Weatherford, explains how a framework for real time geomechanics optimises drilling and borehole stability in complex reservoirs.

Slow motion precursors give earthquakes the fast slip

At a glacier near the South Pole, earth scientists have found evidence of a quiet, slow-motion fault slip that triggers strong, fast-slip earthquakes many miles away.

Slow earthquakes: It's all in the rock mechanics

Earthquakes that last minutes rather than seconds are a relatively recent discovery, according to an international team of seismologists. Researchers have been aware of these slow earthquakes, only for the past five to 10 years because of new tools and new observations, but these tools may explain the triggering of some normal earthquakes and could help in earthquake prediction.

Human-made earthquake risk reduced if fracking is 895m from faults

The risk of human-made earthquakes due to fracking is greatly reduced if high-pressure fluid injection used to crack underground rocks is 895m away from faults in the Earth's crust, according to new research.

Lessons from Pohang: Solving geothermal energy's earthquake problem

A geothermal energy project triggered a damaging earthquake in 2017 in South Korea. A new analysis suggests flaws in some of the most common ways of trying to minimize the risk of such quakes when harnessing Earth's heat for energy.

Geomechanics and Fluid Flow in Geothermal Systems

The deployment of geothermal systems is being hindered by insufficient permeability of the reservoir rock, excessive induced seismicity during reservoir stimulation, and geochemical reactions accelerated by high temperature that lead to corrosion and scaling.
To overcome these challenges, interdisciplinary approaches
that investigate relevant processes occurring during geothermal energy exploitation are necessary

Boosting the efficiency of carbon capture and conversion systems

New design could speed reaction rates in electrochemical systems for pulling carbon out of power plant emissions.

Evaluating geothermal potential in Yukon through
temperature gradient drilling

A major goal of the project is to determine whether ground temperatures warrant further geothermal exploration in the territory.

Micro-Slimtube Shrinks EOR Screening From Months to a Week

Interface Fluidics carved out a niche for itself in the oilfield testing sector a few years ago with a new alternative to coreflooding. Now, along with Equinor, the Calgary-based company is taking on another industry laboratory stalwart: the slimtube test.

Plug and Frac: Grid-Powered Pressure Pumping

Is it possible to fracture a well using power off the grid? The answer is yes, but sharp electric engineers are required.

Shuttle Concept Brings CO2 to Subsea Reservoirs

A new idea from Equinor calls for autonomous submarines to transport CO2 from the surface to the seabed. The Norwegian operator says the shuttles could also carry oil and water for injection.
