Basic Relationships of Well Log Interpretation

a limestone composed primarily of calcium carbon-ate). In the early days of log interpretation (with limit-ed measurements), this was usually a sufficient description. Probably the first instances of lithologic effects on the logs were observed in shaly or clay-con-taining sandstones. With the advent of multiple poros-

2: Plateau phase in which calcium continues to flow into the cell and potassium flows out. (Note that phases 1, 2, and the beginning of 3 are referred to as the refractory period because no stimulus can excite/depolarize the cell). 3: Rapid repolarization during which calcium channels close but potassium flows out of the cell at increased speed.

Hardness in Drinking-water - World Health Organization

Calcium concentrations up to and exceeding 100 mg/l are common in natural sources of water, particularly groundwater. Magnesium is present in natural groundwater usually at lower concentrations (from negligible to about 50 mg/l and rarely above 100 mg/l), so calcium-based hardness usually predominates (National Research Council, 1977).

3. The Winkler titration for the determination of dissolved oxygen involves the treatment of the sample with iodide ion (I-) in the presence of manganese ion catalyst (Mn2+) as follows. O2 + 2 Mn 2+ + 4 OH-Æ 2 MnO 2(s) + 2 H2O MnO2(s) + 4 H + + 2 I-Æ Mn2+ + I 2 + 2 H2O The liberated iodine is then titrated with a standard thiosulfate solution.
