The Use of Hydraulic Fracturing in Stimulation of the Oil and Gas Wells in Romania

This paper presents the application of hydraulic fracturing method in Romania, exemplified by three case studies. In current conditions which oil and gas prices have risen above limit affordability, one few producers Europe, is trying to solve problems that arisen through various methods, are as follows: offshore drilling, underground storage, field rehabilitation increasing efficiency applied technologies. The a safe process, with minimal environmental implications certain economic benefits. important thing necessary energy now, desired quantities expenses. authors sought include key issues this technology Romania. scientific literature on topic has helped us interpret data from difficult situations were real support our activity. We need provide security we do not lot resources. Under these conditions, reactivation existing deposits extension production period essential elements. designed corresponding geological structure obtained investigations, database analyzed wells company’s archive elements used simulation programs. Thus, values area about pore fluid permeability, layers stress, Young’s modulus fracture toughness established. fluids for operation proppant chosen each case, accordance recommendations, team. Testing technologies different variants pumping program was carried out using Fracpro program. presented article some best solutions found. step-by-step flow test find expansion pressure closing case. mini-frac established corrections during quickly reduced costs. allowed anticipate flows pressure, leading choice equipment. operations performed only after projected anticipated benefits covering investments use equipment itself. Knowing measured well communication gas/oil reservoir, could be made simulator. Two an well. results two-year interval also indicated comparison estimated production.
