1 Innvative Petrtech Slutins, Inc Integrating Cre, Well Lg and Well Test Data Instructrs: William Clay Kimbrell, P.E., C.P.G., P.G. Dr. Maghsd Abbaszadeh, Ph.D. Duratin: Level: 5 days Basic-Intermediate Curse Descriptin The curse prvides imprved linkage between the techniques f cre, lg and pressure tests used at varius scales t evaluate reservir quality, reservir hetergeneity, mdel petrleum reservirs t imprve understanding f the prductivity ptential f il and gas reservirs and assess prductin prblems fr remedial actins fr maximizing the recvery f hydrcarbns. As such, the curse prvides the participants with methds t acquire, evaluate, interpret and integrate varius gelgical data (including mineral cntent, rck prperties and pressure/temperature regimes) by means f whle and sidewall cring, lgging and well testing t mre fully utilize these data in develping a cmprehensive picture f the reservir t imprve the understanding f the prductivity ptential f il and gas reservirs and becme mre intuitive f the knwledge gained frm the data. The curse will present methdlgies t integrate petrphysical infrmatin with ther dynamic pressure data and pressure transient well test infrmatin. Prper and adequate attentin t naturally fractured reservirs will be given in this data scientific data analysis and integratin effrt. Ample hand-n exercises cmbined with field examples will be prvided in wrkshp frmat t enhance learning and knwledge f participants during varius phases f the curse. Cmmercial sftware f ARCGIS and Gestatistical Analyst will be utilized fr sme applicatins t integrate infrmatin frm different surces. Special field case studies will illustrate intricacies f cre, lg and well tests data integratin fr defining reservir flw units, well prductivity and ptential il and gas recvery prblems. The field case studies address practical appraches t slve prblems assciated with cmplexity f reservir cnditins such as lithlgy, faulting, natural fractures, cning and s n. Learning Outcme Learn basics f rck mineralgy, rck prperties, reservir pressure and temperature develpment Understand varius surces f data and purpses f data acquisitin fr reservir analysis and quality Learn hw t assemble and integrate reservir and wellbre data t frm a cmprehensive and cherent reservir descriptin and rck quality discriminatin. Use cre and lg data t identify and characterize flw units and reservirs cntinuity Generate gelgically-driven permeability-prsity relatins fr reservir depsitinal settings Learn hw t analyze and interpret cre, lg and well test data t judge reservir cntinuity, limits and fluid cntacts Use MDT testing fr vertical permeability f reservir units. Relate k v/k h ratis t reservir quality Evaluate well prductivity and identify prductin prblems Perfrm OOIP estimates fr reserves Wh Shuld Attend The curse is designed fr starting t mid-level gelgists, gephysicists, reservir engineers and thse persnnel wh wish t imprve their skills/understanding f reservir analysis thrugh integrating cre, lg and well test data infrmatin at different scales and different accuracy.
