  1. Design, environmental impact and performanceof energized fluids for fracturing oil and gas reservoir rocks of Central EuropeAcronym: ENFLUID Project Promoter – Politechnika Śląska Norwegian Partner – University of Stavanger Polish Partner – Oil and Gas Institute - NRI Project duration: June 2013 – April 2016 Budget and receivedfunding: 4 062 628 PLN (990 064 Euro) PROJECT KICK-OFF CONFERENCE Polish-Norwegian Research Programme Core 2012 Call & CCS 2013

  2. Hydraulicfracturingis an engineeredpropagation of fracturesin a rock by means of fluidsinjectedat high pressureinto a well. Itisessential for producinghydrocarbonsfromunconventionalformations. To avoidformationdamage (swelling of clayminerals ) by a waterbasedfracturing fluid - substitutingwater by gasesispossible. Suchfracturingfluidsarecalledenergizedfluids. Development of optimal energized fracturingfluidcompositions for use in oil and gas reservoir rocks formations in CE 1. Petrophysical, mineralogical, and geochemicalanalyses in formulating the criteria screening the energized fluid fracturing and EOR 2. Effects of fluids influence on the geochemistry of theformation 3. Composition of fluid for stimulationof differentformations of CE 4. Mutual interactions between the fluids and the fractured rock 5. Impact of designed fluids on the formation damage 6. Flowback – treatmentor recycling Project objectives PROJECT KICK-OFF CONFERENCE Polish-Norwegian Research Programme Core 2012 Call & CCS 2013
