Managing Risk and Reducing Damage From Well Shut-Ins
A technical synopsis of major considerations for unconventional wells facing prolonged shut-ins. The review includes deciding factors for kill fluid selection and risks of incompatible fluid mixing.
Australia Study Finds Few Environmental Effects From Hydraulic Fracturing in Coal Seams
A 3-year study of air quality, soils, groundwater, and waterways found few to no effects as a result of hydraulic fracturing operations in Surat Basin coal seam formations.
The US Fracturing Market Is Sinking, But How Low Will It Go?
Shale producers are pulling completions crews out of the field to respond to the recent price crash, but the contraction has only begun.
Podcast: Highlights from SPE Hydraulic Fracturing Technology Conference
In this episode, we discuss some of the latest research and emerging techniques that were shared at the industry’s leading hydraulic fracturing gathering earlier this year.
The Top Stories of 2019
The most read stories reflect interest in the digital transformation, the energy transition, and shale operations.
To Spark Real-Time Revolution, Fracture Diagnostic Firms Partner Up and Innovate
The types of advancements made in real-time drilling data acquisition and processing are now on the doorstep of the North American completions sector. Technology developers are banding together under the umbrella of “coopetition” in a bid to change the way producers fracture tight reservoirs.
Shale Sector’s Switch to Slickwater Highlights Compatibility Issues with Produced Water
Not all friction reducers are created equal. With dozens of varieties on the market, industry research suggests that oil and gas companies be choosy.
To “Right Size” Fractures, Producers Adopt Robust Monitoring and Custom Completions
If you can see it, then maybe you can control it. This sums up the latest quest that the unconventional engineering community embarked upon to get a better understanding of proper well spacing and how fractures really interact.
Permian Basin Frac Hit Notification System Under New Management
First developed as a proprietary system by a large Permian Basin operator, this hydraulic fracturing schedule exchange will be run by a data company and opened up to the entire North American shale sector.
New Merger to Create Third-Largest US Pressure Pumper
As the hydraulic fracturing market faces pressure to lower costs, Keane Group and C&J Energy Services announce they will combine their businesses.
New Operators, Well Designs Drive Record Gas Production in Haynesville
After a long cooling off period, this dry-gas shale play is once again red hot.
EIA Adds New Plays to Shale Gas, Tight Oil Reports
The agency updated its methodology and production volume estimates to factor increasing production from new, emerging plays as well as older plays that have rebounded thanks to drilling advancements.
To Solve Frac Hits, Unconventional Engineering Must Revolve Around Them
The struggle to overcome the challenge of frac hits has led to a critical dialogue about which pathway the shale sector should take. One idea is to simply put the problem at the center of every major decision.
UK Shale Flow Test Positive, But No Regulatory Relief in Sight
UK’s first horizontal shale well has yielded positive results after an initial flow test. But further testing—and fracturing of a second well—will have to come amid a continuation of UK’s stringent regulations on induced seismicity.
Reservoir-on-a-Chip Technology Opens a New Window Into Oilfield Chemistry
An oil and gas startup has attracted the business with a major operator thanks to its ability to forecast whether production-enhancing chemicals will work as advertised.
Frac Hits To Take Center Stage at SPE Hydraulic Fracturing Conference
The upcoming event will provide the shale sector with a venue to share new learnings and approaches meant to overcome one of its greatest subsurface challenges.
Gas Begins Flowing From UK Shale Well
Small quantities of gas and water are flowing to the surface from the UK’s first horizontal shale well—just days after operator Cuadrilla paused injection work for a second time amid earthquakes.
Small Earthquakes Pause Fracturing of UK’s First Horizontal Shale Well
Cuadrilla has encountered its first bumps in the road while fracturing its Preston New Road shale gas well, with two quakes already temporarily halting injection operations.
Company To Fracture First UK Horizontal Shale Wells
Cuadrilla Resources will test the two wells over the next 6 months to determine how much gas it can initially recover from the Bowland Shale.
Innovative Pressure Map Offers Insights on Frac Hits
Well-interference issues can be hard to diagnose, but this startup may be figuring that out. The data-driven process it developed can also help operators come up with more effective ways to use diverters.
Official: Lack of Industry Knowledge Hampered EPA Study on Hydraulic Fracturing and Drinking Water
A professor who the EPA charged with reviewing its 2016 study on hydraulic fracturing’s possible drinking water impacts shared her observations on the flawed process that led to the agency’s final conclusion.
UK Shale Horizontal Drilling Under Way, Fracturing to Follow
Overcoming numerous regulatory hurdles, Cuadrilla Resources is pressing ahead with its plans to fracture a well in the UK for the first time since 2011.
Natural Fractures Add Little to Shale Gas Reservoir Productivity
Senior Research Scientist and SPE Distinguished Lecturer Ian Walton uses a semianalytic shale gas production model to show that natural fractures, contrary to the intuitive beliefs of many, do not contribute significantly to production.
