A foamed composition includes a base fluid, a graphene particle, one or more surfactants, a gas, and an inorganic acid. The foamed composition has a foam quality in a range from 50 to 90 vol/vol % at a temperature in a range from 120° C. to 165° C. A method of stimulating a hydrocarbon-bearing formation includes introducing the foaming composition into the hydrocarbon-bearing formation under a pressure greater than fracturing pressure of the hydrocarbon-bearing formation to generate fractures in the hydrocarbon-bearing formation and generating a foam from the foaming composition inside the hydrocarbon-bearing formation using a gas. The foam has a half-life of 130 to 260 min at 200° F.

A method for removing liquid buildup in gas wells may include introducing a first aqueous solution and a second aqueous solution into the wellbore such that the first aqueous solution and the second aqueous solution may intermix within the wellbore. The first aqueous solution may contain a nitrogen-containing compound and the second aqueous solution may contain a nitrite-containing compound and a foaming agent. The method may further include maintaining the intermixed solution in the wellbore such that gas, heat, and foam may be generated, and removing the excess fluid from the wellbore. Furthermore, the method may include introducing an acid or acid precursor into the wellbore, releasing an acid from the acid precursor into the intermixed solution, and maintaining the acid with the intermixed solution in the wellbore to adjusted the pH of the intermixed solution to less than 7.0.

Method and composition to remove liquid build up in gas wells

An acid mixture includes hydrochloric acid, a monoamine corrosion inhibitor, and at least one of a diamine corrosion inhibitor and an acid additive. A method for inhibiting corrosion in an acid treatment operation includes introducing an acid mixture comprising hydrochloric acid and a monoamine corrosion inhibitor into at least one of a subterranean formation and subterranean wellbore. The method also includes maintaining the amount of the monoamine corrosion inhibitor in the acid mixture in the subterranean formation and/or the subterranean wellbore in a range of 10 ppm to 400 ppm for the duration of the acid treatment operation. The corrosion rate of steel parts of an acidic fluid circulation system in the acid mixture may be within an acceptable corrosion rate in a temperature range of 20&#xb0; C. to 135&#xb0; C.

A method of stimulating a hydrocarbon-bearing formation may include generating a foamed fracturing fluid having a half-life of 160 to 300 min at 77&#xb0; F. The foamed fracturing fluid may comprise a fluorosurfactant, a nanoparticle, and a gas phase. The method may then include introducing the foamed fracturing fluid into a hydrocarbon-bearing formation under a pressure greater than the fracturing pressure of the hydrocarbon-bearing formation to generate fractures in the hydrocarbon-bearing formation. Another method of stimulating a hydrocarbon-bearing formation may include introducing a foaming composition into the hydrocarbon-bearing formation under a pressure greater than fracturing pressure of the hydrocarbon-bearing formation to generate fractures in the hydrocarbon-bearing formation. The foaming composition may include a fluorosurfactant, a nanoparticle, and a gas phase. The method then may include generating a foam from the foaming composition inside the hydrocarbon-bearing formation. The foam may have a half-life of 160 to 300 min at 77&#xb0; F.

Systems, methods, and apparatus for a three-dimensional (3D)-printed vessel for wettability assessment of fracturing proppants are disclosed. The vessel includes a base component including a threaded cylindrical portion extending outward from a first side of the base component. The cylindrical portion has a particular thread profile. The base component defines a cavity sized to contain a proppant sample. A cap is configured to be screwed onto the threaded cylindrical portion after the proppant sample is injected into the cavity. A surface of the cap is shaped to flatten a proppant surface of the proppant sample. The cap is threaded with the particular thread profile. A pin is configured to be partially screwed onto a second side of the base component before the proppant sample is injected into the cavity. The second side is opposite to the first side. Other embodiments may be described or claimed.
