摘要： Methods for treating a formation may include introducing components of a treatment solution into a wellbore such that the treatment solution contacts the formation to be treated, where the treatment solution may include urea, urease, a calcium ion source, one or more polysaccharides, a casein protein, a protease, an ionic compound, and a sugar, where the formation may have an amount of sand production before treatment and may be in fluid contact with the wellbore, and where an amount of sand production after treatment may be less than the amount of sand production before treatment. Consolidated sand structure compositions may include previously unconsolidated sand interlinked by inter-particle cementitious bonds comprising deposited calcium carbonate crystals, where the consolidated sand has a structural strength and the consolidated sand structure is porous to permit fluid flow through the composition.

摘要： A method for using genomic data to locate a reservoir is provided. The method includes collecting samples in a field over a reservoir. A genomic analysis is performed on the samples to obtain genomic data. The genomic data is clustered to classify sequences of microbial communities associated with using hydrocarbons for energy. The genomic data is used in an artificial intelligence model to identify a drilling site for hydrocarbon production.

摘要： Methods of enhancing water injectivity into a subterranean wellbore may include injecting a first composition comprising nitrate anions having a nitrate concentration into a target zone of the subterranean wellbore; injecting a second composition comprising nitrate anions into the target zone of the subterranean wellbore, where the second composition has a nitrate concentration of from about 20% to about 70% the nitrate concentration of the first composition; optionally injecting a third composition comprising nitrate anions into the target zone of the subterranean wellbore, where the third composition has a nitrate concentration of from about 20% to about 70% the nitrate concentration of the second composition; and injecting water, where the water injection pressure is reduced by about 5% to 25% compared to the water injection pressure in an untreated subterranean wellbore, where the nitrate anions are reduced by bacteria present in the subterranean wellbore.

摘要： A biocide testing system includes test columns, a bypass tube, control valves, and a control system. Each test column includes biocide test coupons. The bypass tube is fluidly coupled to each of the test columns. Each control valve is coupled between a respective test column and the bypass tube. The control system performs operations including: controlling the control valves to fluidly couple the test columns to a water source; controlling a pump to circulate water from the water source into the test columns to immerse each test coupon in water; controlling the control valves to fluidly isolate the test columns from the water source and to fluidly isolate each test column from the other test columns; controlling a particular control valve to fluidly couple a particular test column to a biocide source; and controlling the pump to circulate biocide from the biocide source into the particular test column to immerse the test coupons in the particular test column in biocide.
