Good formation access is the key to expanding stimulated reservoir volume and increasing production from hydraulic fractured, unconventional wells. In Europe, using long perforated intervals for these treatments in tight-gas operations in wells has led to perforation “screenouts.” Higher fluid viscosities in combination with larger pad volumes were often used to avoid these screenouts, as they were thought to be related to the...

About Klaas van Gijtenbeek
Klaas has a BSc in Geochemistry and a MSc degree in Structural and Applied Geology from the University of Utrecht in the Netherlands and started working for Halliburton in 1981. Klaas started his career as a Field Engineer in Holland and got involved in the design, execution and analysis of hydraulic proppant fracturing treatments in Europe from 1984 onwards. In 2002 he was transferred to Russia where he was lead engineer for all frac operations. He became a Technical Advisor for Fracturing in Kazakhstan in 2007. In 2010 he was transferred back to Europe and became a member of Halliburton’s Technical Team with a focus on Well Stimulation Operations in the ESSA and Eurasia Region. During his technical career Klaas has contributed to more than 15 technical papers and has had the pleasure to serve on several technical committees for various SPE conferences.
