  Ferric iron contained in a fracturing fluid is prevented from precipitating or otherwise disadvantageously reacting by adding a thioalkyl acid compound to the fracturing fluid. The thioalkyl acid compound reduces ferric ion to ferrous ion which remains in solution at pH levels below about 7.5. The thioalkyl acid compound has the formula: where n is an integer from 1 to 10; Z is R or M; R is hydrogen, -(CH₂)xCH₃,-CH₂COOH or -(CH₂)xC₆H₅ wherein x is 0 or an integer from 1 to 6; M is sodium, potassium, ammonium, calcium, magnesium or H₃N⁺OH; and d is 1 when Z is R, or d is 1 or 2 when Z is M to match the valence of M.

  A well acidizing composition for acidizing a hydrocarbon bearing subterranean formation in the presence of ferric ions includes a mineral acid solution, an electron donor agent, a primary electron transfer agent and a secondary electron transfer agent. The primary electron transfer agent is a source of vanadium ions. The secondary electron transfer agent is a source of iodide ion or iodine. The electron donor agent and primary and secondary electron transfer agents function together to reduce ferric ion present in the mineral acid solution to ferrous ion which in turn prevents ferric hydroxide and/or free sulfur from precipitating out of the solution and reduces the formation of sludge in crude oil in the formation.
