Research on the timing of polymer flooding oil and water well fracturing [PDF]

E3S Web of Conferences
Fracturing technology is the main measure to increase production and injection in oilfield production. With the gradual expansion of the scale of polymer flooding, the proportion of fractured Wells also increases year by year.

The politics of hydraulic fracturing in Germany : party competition at different levels of government

, 2016
Hydraulic fracturing has been practiced in Germany for decades, and several attempts have been made to legalize and regulate new drilling methods, which eventually led to the approval of a law to effectively ban this activity in 2016.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Hydraulic fracturing in ice boreholes: Theory and tests

, 2019
Hydraulic fracturing is the well-known phenomenon that can occur intentionally, as it is used in the petroleum industry to stimulate the flow of natural gas or oil, or naturally, for example, as a reason for calving of ice shelves.
