Fracturing/pressure pumping
When Occidental Resources switched to bigger fracture designs to produce more oil, it produced more water as well. Based on research done since, they cannot have one without the other, and at the oil prices recently seen, that’s OK.
The authors of this paper demonstrate that future produced-water management and scale-mineral control may need to consider the sequential exposure effect of steel, cement, and shale on fluid chemistry and mineral precipitation.
Pennsylvania children living near unconventional oil and gas developments at birth were two to three times more likely to be diagnosed with leukemia between the ages of 2 and 7 than those who did not live near this oil and gas activity, after accounting for other factors that could influence cancer risk, a novel study from the Yale School of Public Health finds.

In this paper, the authors discuss what components have contributed to recent proppant-placement cost reductions and use several case studies to illustrate the potential for further cost reductions. -
This paper presents a new real-time method to estimate stage-to-stage interference and well-to-well interference and their implications on completions efficiency.

Oil companies would have to pay a premium for the hardware and services needed for rapid expansion. But is that likely?
-
Liberty will be integrating Seismos’ measurements-while-fracturing system into its completions service to analyze near-wellbore fracture networks and create a near-field connectivity index.

This paper presents an optimization project that was implemented in the Khazzan and Ghazeer fields of Oman to optimize the post-fracturing cleanup and testing period to reduce hydrocarbon flaring and CO2 emissions as well as the testing cost without compromising the overall well cleanup and testing objectives.

A team of engineers did something no one had done before: a full-scale fracturing test on the surface. The results surprised the fracturing experts involved.
-
The message from a single chart’s data from the first full-scale hydraulic fracturing surface test is simple: Far less proppant flows out of the first clusters passed in a stage than the last ones.

SponsoredFrac operators are continuously challenged by pressures to increase ROI and simultaneously decrease emissions. But is it really possible? New technology released in February from Catalyst Energy Services proves that it is possible. And the results are compelling.
-
Efforts to mitigate the potentially harmful effects of hydraulic fracturing have traditionally been divided along two fronts—those that primarily focus on protecting the environment and wildlife and those that focus on protecting humans and domestic animals. But it doesn’t have to be that way.

Induced seismicity put a stop to hydraulic fracturing in the UK, but rising natural gas prices might change that.
