Mineral oil base fluid oil-based mud

In the previous post, we discuss the base fluid as diesel oil-based mud but there are several drawbacks to using it. Therefore, some operators choose to use mineral oilinstead.

Mineral oil or liquid petroleum gas is a byproduct of the distillation of petroleum to produce gasoline vehicle. It contains a lower concentration of nitrogen and aromatics than diesel.The mineral oil consists of several types of paraffin as straight-chain type, branched and cycloparaffin type.

From a performance stand drilling, many places around the world have shown that mineral oil has better performance drilling fluid based diesel . However, mineral oil biodegradation was very slow because of its branched and cyclic molecules.
