One of the major challenges in Abu Dhabi onshore oil fields is the substantial increased water production with time. This is mainly attributed to unforeseen the presence of sub seismic faults and fractures along the drain hole. To address this, smart completions are being introduced to control water production by moderating the flow profile across the completed interval, whereby water and gas breakthrough are delayed in producing wells and injection rates are optimized in water and gas injectors across the full wellbore face. The smart completion design is supported by dynamic and static reservoir information. In this study, production logging tool (PLT) data was available to benchmark and confirm the results from dynamic simulation modeling. However, geologic features that cause the uncontrolled water inflow were not confirmed due to lack of lack of image data.A novel methodology has been implemented allowing resistivity image acquisition in workover wells by utilizing a compact memory tool that addresses the challenge of accessing old wells in Abu Dhabi onshore oil fields. The poor condition of the well is a result of prolonged production, post-stimulation and subsequent borehole degradation. The technique consists of acquiring data using drill pipe with significant savings in rig time and a higher chance of accessibility when compared to alternative techniques. This technique also protects the tool from becoming stuck and incurring damage during entry, thus improving data acquisition quality and minimizing the possibility of re-runs. When compared with common pipe-conveyed wireline alternatives (TLC) in previous wells, up to 33% savings in logging time was observed with a much safer operation.The procedure was achieved with success in terms of image data quality and execution time. In the absence of core data, the microresistivity imaging technique gives the best possible picture of the rock. It has been effective in characterizing rock fabric required for structural analysis (including fracture identification and fault identification and analysis), geomechanics, sedimentology (including paleocurrents analysis and facies determination) and image petrophysics applications such as identifying vuggy secondary porosity. A quick-turnaround in data processing allows the introduction of detailed fractures and fault interpretation, which in turn allows optimization of the completion design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
