Effect of miscibility and injection rate on water-saturated CO2 Injection
, 2021Water-saturated CO2 (wsCO2) injection into oil reservoirs has recently been proposed to provide better oil recovery and CO2 storage than can be obtained by pure CO2 injection.

Continuation Rates Among Injectable Contraceptive Users
Family Planning Perspectives, 1996Few published data exist on the ongoing use of depot medroxyprogesterone acetate, the injectable contraceptive. Women who obtained the injectable from Planned Parenthood of the Rocky Mountains between January 1993 and March 1995 were followed to ascertain continuation rates for the method.

Injection rate: A factor in contrast reactions?
Clinical Radiology, 1990A prospective study comparing the frequency of contrast reactions by the rate of contrast injection is presented. One hundred patients undergoing excretion urography with meglumine diatriazoate (18%) and sodium diatriazoate (40%) mixture (Urografin 325) were randomised into slow (mean 0.975 ml/s) and rapid (mean 2.575 ml/s) injection groups.

Minimizing Hydrate Inhibitor Injection Rates
International Petroleum Technology Conference, 2014Abstract Inhibitor injection is probably the most popular option for avoiding gas hydrate problems. However, inhibitor injection rates are normally designed based on worst operating conditions (i.e., maximum pressure and minimum temperature) with significant safety margin (e.g., 3–5 °C). Although the system pressure

An on-line measurement method of injection rate of high pressure common rail system
, 2020This paper presents a new on-line measurement method of injection rate based on the injector inlet pressure. The Riemann wave theory is applied to the fuel system, and the mathematical relationship of injection rate (G) and pressure (P) under single ...
