    Abstract: The systems and method described in this specification relate to at least partially restoring porosity and brine permeability of carbonate core samples. The systems and methods include extracting a carbonate core sample from a subterranean formation. The extracted carbonate core sample is inserted into a core flooding test machine. A first porosity and a first brine permeability of the extracted carbonate core sample is measured. A fluid is pumped through the extracted carbonate core sample to flood the carbonate core sample. The fluid includes at least one of a high-molecular weight polymer solution and a gel particle solution. The systems and methods include at least partially restoring the porosity and the brine permeability of the carbonate core sample by pumping an oxidizing solution through the flooded carbonate core sample and heating the carbonate core sample to a temperature of at least 60° C. after pumping the oxidizing solution through the carbonate core sample.

    Abstract: The present invention relates to a multi-capillary force curve averaging method based on the overall virtual measurement of a plurality of samples. The method includes the following steps: 1, taking m types of rock samples, obtaining a capillary force-saturation curve, an apparent volume and a porosity of each sample; 2, inspecting the quality of the capillary force-saturation curve of each sample and preprocessing the end points of each curve; 3, calculating an averaged wet phase saturation corresponding to different capillary force values of the plurality of samples under the overall virtual measurement of a plurality of samples; and 4, denoting data points on a graph by using the wet phase saturation as the abscissa and capillary force as the ordinate, and finally connecting all data points smoothly to obtain the averaged capillary force curve. This method of the present invention is reliable in principle and easy to operate, can be directly operated on the capillary force curves, is also suitable for various types of samples with different physical properties in consideration of the influence of the numbers of reservoirs represented by samples, has a wide range of applications, and accurate and convenient calculation results, and is more consistent with actual working conditions.

    Abstract: Systems and methods determine a filter efficiency of a fluid filter. A characteristic of fluid flow of a fluid is monitored at a first point and at a second point on a flow path of a fluid filter. A particle absorption level of the fluid filter is determined that is a difference in the characteristic of the fluid flow at the first point and the second point. The particle absorption level of the fluid filter is at a particle absorption saturation level based on the difference in the characteristic of the fluid flow at the first point and the second point. The particle absorption saturation level is an indicator that the particles retained by the fluid filter is decreased and replacement of the fluid filter is required to increase the particles retained by the fluid filter to be above the particle absorption saturation level.
