What are s.g. units ??

  1. Jul 5, 2016 #1
    Hi all,

    I am currently trying to understand a paper which presents a model for sand production and wellbore collapse in the oil&gas industry.

    The paper refers to stresses and pressure in "s.g." instead of Pa or other pressure/stress units... values tend to range from 0.4 s.g. for cohesive rock strength to 1.88 s.g. overburden stress at 1.2km depth.

    Anybody knows what those units are ? I seem to get correct values when inputting my own data in Pa. But I wanted to make sure I wasn't missing out a conversion factor.

    Thank you
