Geomechanics of subsurface water withdrawal and injection

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Rapid injection of rocuronium reduces withdrawal movement on injection.

STUDY OBJECTIVE To test whether rapid injection of rocuronium reduces withdrawal movement on injection. DESIGN Randomized, prospective trial. SETTING Operating room in a university hospital. PATIENTS 150 ASA physical status I and II patients aged 18 to 60 years, undergoing general anesthesia. INTERVENTIONS Patients were randomized to three groups. After undergoing anesthesia induction w...

Survey on Housing Equity Withdrawal and Injection

Over the past few years, household borrowing against the stock of housing has increased by more than household spending on new housing and renovations. As a result, the household sector has effectively extracted equity from the housing stock, though the net amount withdrawn has recently been declining. The signifi cant equity withdrawal over 2001 to 2004 stands in contrast to experience in prev...

Were the May 2012 Emilia-Romagna earthquakes induced? A coupled flow-geomechanics modeling assessment

Seismicity induced by fluid injection and withdrawal has emerged as a central element of the scientific discussion around subsurface technologies that tap into water and energy resources. Here we present the application of coupled flow-geomechanics simulation technology to the post mortem analysis of a sequence of damaging earthquakes (Mw= 6.0 and 5.8) in May 2012 near the Cavone oil field, in ...
