A method and system for labeling and identifying a sample, including a rock core sample, after determining a physical primary label has been compromised is provided. The method includes labeling the sample by placing a physical primary label on the sample or sample container, creating a first rollout image of the sample for a secondary label, and storing the first rollout image in a secondary label digital database with a sample identifier. The method continues for identifying the sample after determining the physical primary label has been compromised by creating a secondary rollout image of the sample and searching the secondary label digital database using the second rollout image to create a plurality of matching scores using a machine learning or deep learning image matching technique. The matching scores are then evaluated to determine an identify of a sample and the sample is re-labelled using a replacement primary label.

Sample labeling method using image-matching

Described is a method for enhanced carbon dioxide (CO) sequestration in geological formations. The method includes dissolving COin a low salinity fluid to form a CO-brine solution. The low salinity fluid includes sodium (Na) ions and sulfate (SO) ions. The CO-brine solution is injected into a geological formation, and the COreacts with the geological formation to produce solid carbonate minerals for COsequestration.

Method for enhanced storage of carbon dioxide in geological formations

A method for recovering hydrocarbons from a hydrocarbon-containing formation. The method may include determining the hydrocarbon-containing formation pressure, temperature, and other properties such as the total acid number and total base number of the hydrocarbons, rock type, and brine ionic composition. The method may also include determining a desired amount of wettability alteration of the formation and modeling the formation. Modeling the formation may be based on the determined pressure, temperature, total acid number and total base number of the hydrocarbons, rock type, and brine ionic composition. The method may also include preparing an aqueous wellbore fluid based on the estimated wellbore fluid composition and injecting the aqueous wellbore fluid into the hydrocarbon-containing formation.

Methodology for modeling electrokinetic effects and identifying carbonated water injection parameters

A method for modeling hydrocarbon recovery workflow is disclosed. The method involves obtaining, by a computer processor, stimulation data and reservoir data regarding a region of interest, wherein the stimulation data describe a water flooding process performed in the reservoir region of interest by one or more enhanced-recovery wells. The method may include determining, by the computer processor, a multi-phase Darcy model for the reservoir region of interest using the reservoir data and the stimulation data. The multi-phase Darcy model determines a fluid phase flow rate using a pressure gradient, an absolute permeability value, and a relative permeability value. The method may include determining, by the computer processor, a plurality of relative permeability values for the reservoir region of interest based on a plurality of fluid-fluid interface correlations and an interpolating parameter.

Low pH-based oil recovery method for carbonate reservoirs

A method of measuring two or more fluid phases in a downhole well bore that comprises measuring a flow of each of the two or more phases at respective ports at which the two or more phases are unmixed within the well bore. In certain implementations, the well bore is inclined at 20 degrees or less to a horizontal axis. Each of the two or more phases can flow at a rate to achieve low Reynolds numbers in a laminar flow regime.
