See half thickness . A resistivity scale used with laterologs and guard logs which compresses high resistivity values. Above midscale, the scale is scaled in resistivity units. The hybrid scale presentation has been replaced by the logarithmic scale on modern laterologs and guard logs. A hydrocarbon and water compound that is formed under reduced temperature and pressure in gathering, compression, and transmission facilities for gas.
Hydrates often accumulate in troublesome amounts and impede fluid flow.
They resemble snow or ice. Water molecules become bound chemically at fixed points as part of the crystal lattice of hydrated substances. The water becomes water of crystallization and loses the properties of the original water. Hydraulic fracturing is a method of stimulating production or injection at a specific depth in a formation of low permeability by inducing fractures and fissures in the formation by applying high fluid pressure to its face. The fluid enters the formation and parts or fractures it.
