“…The main drawback of applying WBMs emerges in the course of drilling a shale formation due to shale swelling which makes the use of WBMs ineffective. This is mainly due to the fact that shale swelling brings other destructive problems such as wellbore instability, lost circulation, and pipe sticking [7][8] which lower the rate of penetration and raise the drilling operation costs. In the 19 th century, OBM was utilized in shale formations.…”

“…The polyglycols ability to reduce the hydration of clay formation was also confirmed by the authors (Balaban et al, 2015) by measuring the capillary suction time and swelling of clay formation. Chemical compounds being the part of polyols group as components of drilling mud may also restrain drilling induced formation fractures and support mechanical stability of the wellbore (van Oort E. et al, 1997;Taugbol et al, 2005;Zamora et al, 2013;Zhang et al, 2015;He at al., 2016;Kazemi-Beydokhti and Hajiabadi, 2018).…”

“…Uwodnione zwierciny na dnie otworu wiertniczego ulegają aglomeracji, przyklejając się do świdra wiertniczego oraz przewodu wiertniczego (rur płuczkowych, obciążników). Zjawisko to często jest określane jako "akrecja" (Mat et al, 2002;Judzis et al, 2007;Black et al, 2008;Mettath et al, 2011, Onuoha et al, 2011He et al, 2016). Akrecję najczęściej tłumaczy się poprzez zwiększenie plastyczności zwierconych części skał ilasto-łupkowych.…”
