Paper Number: SPE-163788-MS
... conditions such as temperature and soil type have on terrestrial risks is lacking. In the present study, different base fluids were tested for terrestrial toxicity using aging conditions and soil types to determine how toxicity could be impacted by site conditions. Four base oils were tested including Diesel...
