Wax　deposition　is　an　intractable　flow　assurance　challenge　for　the　petroleum　industry.　For　wax　remediation,　varieties　of　approaches　have　been　proposed　and　mechanical　pigging　ranks　among　the　most　widely　used　ones.　To　lower　the　risk　of　pig　stalling　and　improve　the　cleaning　efficacy　in　pigging,　this　work　uses　superparamagnetic　nanoparticle　(SPM-NP)　heating　to　soften　the　wax　layer.　It　involves　installing　a　magnetic　field　induction　coil　on　conventional　pig　and　coating　a　nanopaint　on　the　inner　wall　of　the　pipe.　The　SPM-NP　pigging　system　is　actually　a　combination　of　mechanical　pigging　and　thermal　management.　The　yield　stress　of　the　prepared　wax　samples　was　experimentally　determined　to　be　binomially　correlated　to　temperature.　The　COMSOL　software　was　used　to　simulate　the　temperature　field.　A　methodology　to　estimate　the　wax　resistive　force　in　pigging　was　proposed.　It　was　found　that　the　SPM-NP　pigging　system　decreases　wax　resistive　force　by　up　to　20–40%　in　the　given　cases,　which　effectively　lowers　the　risk　of　pig　stalling　accident.　Multiple　factors　affecting　wax　resistive　force　were　also　investigated.　Compared　with　wax　melting　formula,　the　softening　approach　dramatically　slashes　the　required　current　intensity　to　a　realizable　level　for　field　pigging　operations.　It　could　be　a　promising　alternative　for　conventional　pigging　in　wax　remediation　and　hydrate　prevention　for　offshore　pipelines　and　production　tubings.　Copyright　©　2022　Society　of　Petroleum　Engineers
