## Abstract

GSH Dry Lubricant Additive is, chemically, magnesium aluminum silicate. It is a clay rich in titanium, magnesium, and aluminum. As an inanimate object, it does not “function” per se, but rather its properties are as such that it is highly beneficial to the drilling industry. It has a naturally high lubricity, a high stall torque, high gel strength, but a low plastic viscosity. This means that it effectively cools the bit while drilling, reduces friction in the system, supports cuttings better, but is easier to break out of a static gel strength than traditional engineered muds. Finally, as a high suspendability, low solids content material, it acts as a natural gel-state cement for unconsolidated LCM particles, effectively strengthening the wellbore.

## Claims

### Claim 1

A drilling mud additive comprising:
a. a determined volume of water; and
b. GSH Dry Lubricant comprising at least 4 percent concentration by weight of Titanium; wherein said GSH Dry Lubricant is suspended in said water.

### Claim 2 (depends on 1)

The additive of claim 1 further comprising barite to weight said drilling mud additive.

### Claim 3 (depends on 2)

The additive of claim 2 comprising 350 cc of said water, 22 grams of said GSH Dry Lubricant, and enough barite to weight said additive to 12 ppg.

### Claim 4 (depends on 1)

The additive of claim 1 further comprising lost circulation material chosen from the group consisting of calcite and graphite.

### Claim 5 (depends on 1)

The additive of claim 1 further comprising bentonite.

### Claim 6 (depends on 1)

The additive of claim 1 further comprising sapiolite.

### Claim 7 (depends on 1)

The additive of claim 1 wherein said GSH Dry Lubricant is diffused into a polymer.

### Claim 8 (depends on 7)

The additive of claim 7 wherein said polymer comprises a polyvinyl alcohol derivative polymer.
