formation water

Formation water resistivity is one of the key parameters used to determine formation water saturation.

Formation water resistivity is one of the key parameters for precisely determining remaining oil saturation of water flooded zone.

It depends on the composition of reservoir-forming power and the formed time of the formation water and it "s host rocks. "

Metallogenic fluids are mainly rock formation water and meteoric water as well as possible addition of magmatic hydrothermal solutions.

Filtering sea water and formation water have been using as the resources of offshore injection in Shengli oilfield.

Generation, migration, accumulation, preservation and dispersion of hydrocarbon are always associated with or accompanied b formation water.

Compared with well test data, the result demonstrates that the formation water resistivity can be accurately determined by the method.

In water zones, the direction of movement depends on the relative densities of filtrate and formation water.

The high temperature of stratum and incompatible of injected water and formation water are the key points of scaling and pressurizing.

Therefore, this paper presents a study of CO2 miscible flooding mechanism which considers the existence of formation water.

selective surface formation water content of less than 8 per cent of the ceramic body for screen business card printing and membership card.

The movements of formation water and hydrocarbon are of interdependent and inter-restricted relationship.

It is concluded that the formation water type can be used to judge the enclosed quality of fault or fracture.

The hydrocarbon-water phase equilibrium model considering formation water evaporation was established.

The damage of formation water and formation water contained anti-swelling agent to core permeability was tested.

How to identify condensed water and formation water is always a bothering problem as for those low content water gas wells.

In many sedimentary basins the salinity of the formation water increases with depth or compaction .

The formation water in oil layer may have the same chemical features as the neighboring water lay-ers, or in contrast with each other.

deviation factor of natural gas; formation water viscosity; formation volume factor of water; compressibility of formation water.

And the formation water soluble dye difficult microcapsulated, a bit trickier.

High sulfur content gas is soluble in formation water under certain pressure and temperature conditions.

The source and migration dynamics of high formation water salinity in Dongying Depression were analyzed.

High formation water salinity reduces resistivity contrast between oil layer and water layer.

The prediction results show that the Kelameili formation water has only little effect on the gas hydrate formation temperature.

With the gas quantity increasing, the formation water will prolong the mature process of organic matter.

The downhole process works well, but water production is decreasing because of the declination of formation water production.

Use SP log in determination of flooding and how to compute resistivity of formation water in flooded zone are also described.

total salinity of the formation water.

Formation water with low salinity.

The salinity of formation water is changeable, oil and water layers are difficult to identify.
