When water flows through porous media under small pressure gradient, the connate water
will not flow in narrow pores and will block the flow of free water in the adjacent bigger pore.
The greater part of the sediment is therefore flushed and groundwater is rarely stagnant except in those places where saline, presumably connate water
entrapped in aquicludes, persist in depth.
wc]) is the relative permeability to oil at the connate water
saturation, fraction; [[mu].
After characterizing the model, the oil flooding is done using a very precise syringe pump and the connate water
is measured (Figure 1).
Higher concentrations of chloride are attributed to zones of fault-related discharge, and typically increase basinward where marine sediments with saline connate water
Depleted hydrocarbon reservoirs that are filled with connate water (fully water-saturated reservoirs) offer limited storage capacity.
Deep aquifers are found in most of the sedimentary basins around the world (Bachu, 2001a) and typically contain high-salinity connate water not suitable for human consumption or agricultural use.
The special issues related to oil sand processing arising from the combined trace minerals, dissolved gases, connate water
, unrelated organic matter attached to the mineral matter are treated thoroughly.
The first step in the investigation concluded that the water that resided in the pipeline was a combination of the connate water
produced from the reservoir and water formed from condensing vapor caused by changes in the pressure and temperature conditions in the pipeline.
Most mineralogists consider the deposits to be epigenetic, the elements in the ore being carried by hot connate water
heated by igneous activity.
Thus the pore spaces between clay-sized particles may still contain connate water
that was present when the clay was deposited.
If the matrix materials have never had their connate waters
removed by desiccation and/or the historical lowering of water tables in the region, does this mean that all regional dewatering has been along fractures and matrix borders only?
