Enhancement of Well Deliverability and Scrutinize the Proppant DiscretionBased on Net Present Value

摘要

The selection of proppants is quite a challenging task as the cost almost comprises 20% to well over 50%of total fracturing jobs when ceramic is used.So,in the current situation of oil price crises,optimizing theproppant cost in Pakistan,where fracturing cost is twice as compared to the United States of America,notonly provide better-optimized stimulation but also maximizes the Net Present Value.The objective of thisstudy constitutes of two:firstly,to investigate the various types of proppants for peerless fracture parametersbased on the post-frac results by using the FracCade simulator.Secondly,to evaluate the Net Present Valueand select the most effective proppant based on the Net Present Value.In this case study,the research is conducted on scrutinization of proppant discretion based on net presentvalue,the reservoir data under the study is real-time data of x-well of Tobra formation.The averagepermeability of the formation is 1md.The focus of this project is to investigate the effects and potential of25 proppants on hydraulic fracturing treatment.Prior to the selection of the proppants for the evaluation ofNPV,sensitivity analysis is done based on closure stress and fracture parameters to screen out 20 proppants.The final selection of proppant is made on the Net Present Value(NPV)which will decide which proppantwill give the economic edge to the fracturing treatment.The result of the study is based on the investigation of 25 proppants based on the Net Present Value(NPV)of the fracturing treatment.Before the selection of the proppants for the evaluation of NPV.Almost 20proppants have been screened out based on the closure stress and fracture parameters.Finally,5 proppantsafter technical scrutinization are selected for the evaluation of NPV.From 17 proppants,5 proppants areselected based on fracture conductivity.These are selected for the evaluation of NPV.Among the 25proppants,proppant which gives the highest Net Present Value(NPV)is Sintered Bauxite which enhancesthe well productivity up to 3.5 times and gives the Net Present Value(NPV)of $12,548,762.98.
