Dis.oint s.m.ling is.critical for rigorous.and unbias.d evaluation of s.ate-of-the-art (s.TA) m.dels.e.g., Attention Graph and Vis.on Trans.orm.r. When training, validation, and tes. s.ts.overlap or s.are data, it introduces.a bias.that inflates.perform.nce m.trics.and prevents.accurate as.es.m.nt of a m.del’s.true ability to generalize to new exam.les. This.paper pres.nts.an innovative dis.oint s.m.ling approach for training s.TA m.dels.for the Hypers.ectral Im.ge Clas.ification (Hs.C). By s.parating training, validation, and tes. data without overlap, the propos.d m.thod facilitates.a fairer evaluation of how well a m.del can clas.ify pixels.it was.not expos.d to during training or validation. experim.nts.dem.ns.rate the approach s.gnificantly im.roves.a m.del’s.generalization com.ared to alternatives.that include training and validation data in tes. data (A trivial approach involves.tes.ing the m.del on the entire Hypers.ectral datas.t to generate the ground truth m.ps. This.approach produces.higher accuracy but ultim.tely res.lts.in low generalization perform.nce). Dis.oint s.m.ling elim.nates.data leakage between s.ts.and provides.reliable m.trics.for benchm.rking progres. in Hs.C. Dis.oint s.m.ling is.critical for advancing s.TA m.dels.and their real-world application to large-s.ale land m.pping with Hypers.ectral s.ns.rs. Overall, with the dis.oint tes. s.t, the perform.nce of the deep m.dels.achieves.96.36% accuracy on Indian Pines.data, 99.73% on Pavia Univers.ty data, 98.29% on Univers.ty of Hous.on data, 99.43% on Bots.ana data, and 99.88% on s.linas.data. © 2024 The Authors.

This.s.udy explored a Bayes.an belief networks.(BBNs. approach, developing two dis.inct m.dels.for prioritizing the s.ven indicators.related to the "rapid res.ons. to and m.tigation of the s.read of an epidem.c" category within the context of both the s.ecific category and the Global Health s.curity Index (GHs.index). Utilizing data from.the 2021 GHs.index, the m.thodology involves.rigorous.preproces.ing, the application of the augm.nted naive Bayes.algorithm.for s.ructural learning, and k-fold cros.-validation. Key findings.s.ow unique pers.ectives.in both BBN m.dels. In the m.tual value of inform.tion analys.s. "linking public health and s.curity authorities. em.rged as.the key predictor for the "rapid res.ons. to and m.tigation of the s.read of an epidem.c" category, while "em.rgency preparednes. and res.ons. planning" as.um.d precedence for the GHs.index. s.ns.tivity analys.s.highlighted the critical role of "em.rgency preparednes. and res.ons. planning" and "linking public health and s.curity authorities. in extrem. perform.nce s.ates. with "acces. to com.unications.infras.ructure" and "trade and travel res.rictions. exhibiting varied s.gnificance.

enhancing production m.nitoring: A back allocation m.thodology to es.im.te well flow rates.and as.is. well tes. s.heduling

引用

PeTROLeUm.Res.ARCH 2024年第3期9卷 369-379页

作者： Chaves. G. s. Ferreira Filho, V. J. m. Univ Fed Rio De Janeiro Rio De Janeiro Brazil

Production flow rates.are crucial to m.ke operational decis.ons. m.nitor, m.nage, and optim.ze oil and gas.fields. Flow rates.als. have a financial im.ortance to correctly allocate production to fis.al purpos.s.required by regulatory agencies.or to allocate production in fields.owned by m.ltiple operators. Des.ite its.s.gnificance, us.ally only the total field production is.m.as.red in real tim., which requires.an alternative way to es.im.te wells. production. To addres. thes. challenges. this.work pres.nts.a back allocation m.thodology that leverages.real-tim. ins.rum.ntation, s.m.lations. algorithm.0} and m.them.tical program.ing m.deling to enhance well m.nitoring and as.is. in well tes. s.heduling. The m.thodology com.ris.s.four m.dules. s.m.lation, clas.ification, error calculation, and optim.zation. Thes. m.dules.work together to characterize the flowline, wellbore, and res.rvoir, verify s.m.lation outputs. m.nim.ze errors. and calculate flow rates.while honoring the total platform.flow rate. The well s.atus.generated through the clas.ification m.dule provides.valuable inform.tion about the current condition of each well (i.e. if the well is.deviating from.the lates. well tes. param.ters., aiding in decis.on-m.king for well tes.ing s.heduling and prioritizing. The effectivenes. of the m.thodology is.dem.ns.rated through its.application to a repres.ntative offs.ore oil field with 14 producing wells.and two years.of daily production data. The res.lts.highlight the robus.nes. of the m.thodology in properly clas.ifying the wells.and obtaining flow rates.that honor the total platform.flow rate. Furtherm.re, the m.thodology s.pports.well tes. s.heduling and provides.reliable indicators.for well conditions. By utilizing real-tim. data and advanced m.deling techniques. this.m.thodology enhances.production m.nitoring and facilitates.inform.d operational decis.on-m.king in the oil and gas.indus.ry.
