Abstract: 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.

Abstract: A method for the removal of well bore damage, the method including performing an acid cleaning of one or more of a coiled tubing and the well bore using a hydrochloric acid mixture of 7 to 15 wt % hydrochloric acid and displacing the hydrochloric acid mixture with a first fresh water stream. After acid cleaning, a composition comprising at least 10 wt % acetic acid into the wellbore is injected into the wellbore. After injecting acetic acid, gel jetting of the well is performed with a gel mixture, and the gel mixture is subsequently displaced with a second fresh water stream. After gel jetting, an organic solvent mixture is injected into the well bore and allowing the organic solvent mixture to soak for 2 to 6 hours. Finally, a thermochemical mixture is injected into the well bore, thereby increasing temperature and pressure and cleaning build up from the well bore.
