What is KCl drilling mud?
What is KCl drilling mud?
POTASSIUM CHLORIDE (KCl) is a soluble salt that is an extremely efficient shale stabiliser when drilling hydro sensitive clays and shales.
What is KCl used for in oilfield?
Commonly referred to as KCL, our “treated” 98.8% Potassium Chloride (white soluble muriate of potash) is commonly used as an additive in drilling fluids for the oil and gas industry. It is considered an effective clay or shale stabilizer in water sensitive formations.
What is the weight of potassium chloride?
74.5513 g/molPotassium chloride / Molar mass
How toxic is KCl?
Acute oral toxicity of KCl in mammals is low (LD50 = 3020 mg/kg bw). In humans, acute oral toxicity is rare because large single doses induce nausea and vomiting, and because KCl is rapidly excreted in the absence of any pre-existing kidney damage.
Is KCl mud water based?
Potassium-based (KCL)muds are used in areas where inhibition is required to limit chemical alteration of shales. This research study therefore was undertaken to evaluate the inhibition effects of different concentrations of KCL on the rheological properties of water-based mud(WBM) contaminated with shale.
Is KCl a polymer?
Potassium Chloride (KCl) – Potassium chloride is used to inhibit clay hydration….Principal Additives of KCl Polymer Muds.
| Principal Additives of KCl-Polymer Mud | ||
|---|---|---|
| Additive | Concentration, lb/bbl | Function |
| Potassium Chloride | 5 – 60 | Inhibition Source of K+ion |
| Caustic Potash | 0.25 – 0.75 | Alkalinity Control, Source of K+ion |
| Starch | 3 – 6 | Filtration Control |

How do you make a 3M KCl solution?
To make 125 mL of 3M KCl
- Using digital scale, place 27.96 g KCl powder into weigh boat.
- In 150 mL flask, mix 27.96 g KCl with 100 mL H2O.
- Put flask on hotplate/stirrer with stirbar until dissolved.
- Add H2O to bring volume to 125 mL.
What do you mean by percentage composition?
Percent Composition Formula The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100. Here, the quantity is measured in terms of grams of the elements present.
What is antidote for potassium?
In acute overdose situations due to ingestion of potassium salt, the general principles of treatment for overdoses should be followed. Calcium chloride infusion, dextrose and insulin in water, and correction of acidosis with sodium bicarbonate are helpful in controlling the acute, life-threatening cardiac arrhythmias.
How does KCl cause death?
Injection of a lethal dose of KCl produces death by cardiac arrest. KCl eliminates the potassium concentration gradient in cardiac muscle, and the depolarized muscle cannot repolarize.
