Geochemical characterization | SPE

Geochemistry is the study of the chemistry of the Earth and within solid bodies of the solar system, including the distribution, circulation and abundance of elements (and their ions and isotopes), molecules, minerals, rocks and fluids. For geochemists in the petroleum industry, source rock geochemistry is a major focus. Geochemical techniques can determine whether a given source rock is …

High efficiency gel breaker is introduced to reduce the carrying capacity of the ,fracturing fluid, during its postfrac flowback process. Jiang et al. pointed out that the forced closure technique in ,fracturing, operation ahead of the natural fracture closure is another technique to encapsulate the maximum proppants within the fracture [ 7 ].

Consider an example. You are planning an injection operation in an aquifer that is (or will be) into a twenty-foot thick zone with a permeability of 1000 md. The average reservoir pressure is 2000 psi. Suppose that the bottomhole pressure during injection is 2100 psi, the viscosity is 1 cP, the formation volume factor is 1.0, the porosity is 20%, the total compressibility is 1.0 x 10-5 psi-1 ...
