Halliburton Aims For Better Wells With Automated Fracturing
The pressure pumping giant turns to algorithms to get better fractures and fewer problems.
Big Leaps Still to Come in Unconventional Technology
Today’s advancements in unconventional technology are worth marveling over, but there is still plenty of room for growth.
Unconventional Resources: Validating the Smooth Success of HEAL System
PipeFractionalFlow, a spinoff startup from the University of Texas at Austin, uses new theories and equations to make modeling complex multiphase flow more affordable. A model recently developed offers operators an “independent and unbiased” way to validate the system and select candidate wells.
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.

With Over 200 Shale Well Installs, This Slug-Smoothing Lift Technology Is Boosted By Schlumberger JV
Slug flow has made the life of an unconventional production engineer a bit complicated, but a new downhole technology may smooth things right out by solving some big artificial lift problems for the shale sector.
Technology, Efficiency, and Midstream Growth Drive Long-Term Future for Marcellus, Utica
While the collapse in oil price is reshaping opinions about the North American shale revolution and the outlook for oil producers, natural gas producers in the United States are in a somewhat different position
A Practical Simulation Method Capturing Complex Hydraulic-Fracturing Physics
To understand production from shale reservoirs, the role of hydraulically induced fractures, natural fractures, and their interaction in a formation must be captured.
Unconventional Technology Gains Exceed Expectations, but Low Prices Offer a Stern Test
Oil markets displayed their manic-depressive side in August, dropping to around USD 40/bbl early and jumping back to near USD 50/bbl at month’s end.
Do Data-Mining Methods Matter? A Wolfcamp Shale Case Study
Data mining for production optimization in unconventional reservoirs brings together data from multiple sources with varying levels of aggregation, detail, and quality.
Artificial Lift Experts Warn of Long-Term Production Issues in Horizontal Wells
A panel of experts says US shale producers need to rethink their drilling and completion designs as problems mount for horizontal wells when they go on pump. Hanging in the balance is whether long-term production from many shale wells will be achievable.
Shale Industry Needs to Look Within for Solutions That Save
At the recent 2015 Unconventional Resources Technology Conference, a major theme was how companies can improve performance without increasing the size of their budget.
Refracturing With Expandable Steel: A Stronger Alternative to Chemical Diverters?
Enventure Global Technology is working to convince operators that its solid expandable steel liners perform better than chemical diverter agents for refracturing operations. Its technology is called the ESeal ReFrac Liner.
Automated Drilling Technologies Showing Promise
For the past several years, automated drilling has promised to deliver major improvements in drilling performance. But the technology is facing new obstacles that might affect its progress and commercialization.
Going Underbalanced in Unconventional Reservoirs
For the past quarter of a century, underbalanced drilling (UBD) has been a niche technology known to many and practiced by few. It has seen acceptance in the North Sea, where UBD is used to drill through depleted reservoirs.
The New Pathways of Multiphase Flow Modeling
In the realm of enabling technologies, multiphase flow modeling has proven to be one of the most important to the oil and gas industry. Without it, nearly all subsea wells would be too costly or dangerous to develop.
New Oil Sands Technology Debuts in Utah, Promises Low Environmental Impact
In the northeastern desert of Utah, a new type of oil sands extraction technology has been born. The company behind it claims the process is the most cost-effective and environmentally sound way to develop oil sands.
Springer Shale Rising: Continental’s New Niche Play
The United States’ liquids-rich shale experience has been dominated by three major plays: the Eagle Ford Shale in south Texas, the Permian Basin in west Texas, and the Bakken Shale that straddles North Dakota and Montana.
Studying the Sources of Methane Migration Into Groundwater
The rapid development of shale formations over the past decade has led the United States to become the world’s undisputed leader in natural gas production.
The Shale Evolution: Zipper Fracture Takes Hold
Hydraulically fracturing and stimulating multiple horizontal wells in sequence has been rapidly adopted by operators because of the potential for production without introducing unwanted risks.
Searching for Solutions to Induced Seismicity
A sharp rise in seismic events in some areas of the United States where oil and gas production is booming is leading regulators and the industry to examine whether the two are related.
