Low toxicity terpene drilling fluid and drilling fluid additive |
| abstract |
A water based drilling fluid comprises 1 - 8% of an additive comprising saturated terpene, a mixture of saturated terpenes or a mixture of saturated and unsaturated terpenes. The drilling fluid is substantially non-toxic and has an LC-50 greater than 30,000 ppm and preferably greater than 100,000 ppm. The most economic additives are a mixture of saturated and unsaturated terpenes and have at least 30% saturated terpenes. The drilling fluid has the advantage of low toxicity over unsaturated terpene drilling fluids. |
