Experience of the silicate reagents in oil and gas well drilling use

Abstract

The article presents the analysis of incidents occurred while production drilling and side track drilling at the Samotlor field during the period from 2012 to 2023 and the relevance sticking problem occurrence with amount to more than 40%. The reason for the sticking in 90% of cases is the discrepancy between the drilling mud properties and the drilling well geological and technical condition. To prevent sticking the authors propose the boron-silicate solution (BSS) and its analogues use in the composition of drilling washing liquids. The BSS in well drilling high efficiency use is shown. Due to the combination of high inhibitory properties, low fluid loss and reinforcing properties at the same time the reagent allows to drill a well without complications, preserving the productive formation reservoir properties and the well cementing quality improving.
