Two mechanisms are responsible for the swelling and migration of clays, surface hydration and osmotic swelling.
Surface Hydration show little visible signs of swelling, however the pressure greater than 60,000 psi is required to desorb surface hydration moisture.
Swelling and softening of clays due to Osmotic differences is a bigger problem. This occurs when concentration of Ions (like Na+, Ca++, Cl-, etc) in the clay at the wellbore walls is higher than that of the drilling fluid. Due to this difference in ion concentrations (aka osmotic pressure), water moves toward the clay surface causing swelling. The amount of swelling depends up on the concentration of salts in the clay relative to the salts in the fluid.
Hence the objective is to keep a sufficiently high ion concentration in the fluid to prevent swelling.
Clay Stabilizers work on the principle of Cation Ion Exchange, similar to water softeners resins. Water softeners can be regenerated using Salt, KCl, and many other cations. Similarly, Clay’s can be stabilized using a variety of cations.
Using sacks of KCl is a difficult approach, especially with the increased fluid volumes used in fracturing. Handling, mixing and disposal costs related to sacks of KCl are prohibitive. Herein, we will discuss a few potential Clay Stabilizers, compare their performance and economics.
Several options are available as KCl replacements or Clay Stabilizers:
|Product||CST Filtration Time secs|
|Clay Ste ADV™ - 2 gpt||220|
|50% Choline Chloride - 2 gpt||307|
|50% Choline Chloride - 2.8 gpt||219|
|75% Choline Chloride - 2 gpt||220|
|TMAC - 2 gpt||297|
Clay Stabilizer STE Adv is extensively used in frac jobs or oil well drilling, fracturing or fracking.
Clay Ste Adv™ is a liquid product designed specifically for use as a replacement for solid potassium chloride (KCl). Clay Ste Adv™ is biodegradable.
Compatibility with brine, calcium chloride, KCl solutions as well as all known fracturing fluids, cross-linkers and breakers.
