Abstract
The subject invention provides compositions and methods for improved acidizing treatments in oil and gas wells, as well as for enhancing oil recovery. Advantageously, the invention utilizes naturally-derived ingredients to replace and/or reduce chemical acidizing additives in order to simplify acidizing jobs, reduce logistics and improve efficiency. Furthermore, the invention allows for acidizing additives that are typically incompatible to be combined into a stable formulation without high energy input and with reduced need for on-site preparation.
