... tubulars, and minimizing acid additives. However, using this acid to treat wells with asphaltene deposition requires removing asphaltene first using a suitable aromatic-based solvent, and then using a matrix acid treatment. This additional step increases the cost and time needed to execute acid treatments...

...-or frac-packing operations to clean up long intervals after perforating. Success or failure of these treatments is often related to the efficiency of diverting agents, especially for acid treatments on wells with long, heterogeneous intervals or multiple-zone completions. A VES diverting agent...

... long horizontal wells with OH completions. The simplicity of the system makes it the fluid of choice, especially in offshore and sour environments. The absence of metallic crosslinkers in this system eliminates problems associated with sulfide precipitation in sour wells. Acid treatments conducted...

... innocuous brine spacers, to maintain separation of the (spent) acid and completion brine, and the use of an appropriate post-flush acid to maintain a low pH in the spent acid. If a precipitate does form, it can be readily cleaned up by acid treatment, if the acid reaches the occluding precipitate. Complex...

Examples of wells indicating this effect during post-gravel-pack acid treatments are discussed. The theory of why this occurs and calculations...
