Field development studies require, among many other things, reliable estimates of fluid properties.
An accurate characterization of the reservoir should yield consistent estimates of fluid volumes that are originally in place in the reservoir regardless of the method chosen to determine the fluid volumes.
Fluid balance, diureses and haemodynamic status can give only gross estimates of fluid balance.
Unfortunately, estimates of fluid deficit that are based on traditional physiological parameters, such as heart rate, blood pressure, and cardiac filling pressures, are not sufficient.
Indeed, the micropuncture glass capillary method is known to yield more reliable estimates of fluid pressures than the wick-in-needle because it produces less trauma and requires smaller volumes to record IFP (Heldin et al, 2004).
This method requires an estimate of fluid and matrix travel times ((Delta t_{text{fluid }}) = 607 μs m−1, (Delta t_{text{matrix}}) = 182 μs m−1) and compares these with travel times measured in the reservoir ((Delta t_{log})): varPhi_{text{m}} = frac{{Delta t_{text{log}} - Delta t_{text{matrix}} }}{{Delta t_{text{fluid }} - Delta t_{text{matrix}} }}quad left[ - right].
The estimated amount of fluids for the first 24 hours was 11,150 (± 4115) ml LR in the crystalloids only group versus 7,082 (± 5142) ml LR and 1,409 (± 642) ml HES in the HES 200/0.5 (10%) group.
One 24-h recall appears to only yield valid estimates of relative fluid intake for groups, i.e. drinking water expressed as a percentage of total fluid intake.
Using plausible estimates of mineral-fluid interfacial free energies, chlorite growth is not achieved until 5000 years of simulation time.
New robust quantitative estimates of tissue fluid content would allow clinicians to better guide treatment, minimizing reactive treatment decision making.
