The impacts of a natural fracture on the propagation of a hydraulic fracture has been extensively studied in the past decade. However, there were only minor attempts to understand the impact of natural fractures on acid distribution during acid fracturing. This study provides an understanding of the impact of natural fractures on acid fracturing …

The document says that dolomite (a.k.a. crushed stone, calcium magnesium carbonate, and other aggregates) has the following hazard statements: "may cause cancer," "may cause damage to organs (lung) through prolonged or repeated exposure," "causes skin irration," and "causes serious eye irritation." It also pointed out that dolomite is a ...

Dolomite is a naturally occurring mineral and has a low carcinogenic level to humans. However, this can be amplified in the food chain through other marine species. Furthermore, long exposure to this mineral can lead to respiratory problems which have been reportedly observed in dolomite miners5. The washing off of dolomite sand from …
