Abstract

The paper presents the results of well testing of a reservoir subjected to hydraulic fracturing (HF). Pressure build-up recorded is some wells with HF showed no characteristic response of the presence of any fractures. At the same time, the effectiveness of HF could be confirmed by increased production rates and a negative skin factor determined by well test result analysis. To determine the cause of such behavior, a literature review and analysis of influencing factors were conducted. It was found that the main issue masking the diagnostic response is a high mechanical skin effect caused by either incomplete fracture propagation or damage to fracture face zone. It was concluded that the primary reasons for this phenomenon may be related both to the hydraulic fracturing technology itself and to the chemical of the fluids used during the treatment.

Key words:

well testing, pressure buildup curve, hydraulic fracturing, skin effect
