Due to the in.reased deman. for en.rg. resources these days, especially due to the Russian.Ukrain.an.war, the focus of the major coun.ries is turn.n. stron.ly towards improvin. oil production. especially heavy an. extra heavy oil, which represen.s 40% of the world oil reserve. Steam-based an. thermal (EOR) procedures are promisin. techn.ques for recoverin. heavy oil reservoirs, but they suffer from a sequen.e of problems an. complication. that arise after lon.-term application. These complication. comprise steam breakthroug., steam overlap, an. steam/rock in.eraction.. This research presen.s the curren.ly applied techn.ques to maximize the productivity of heavy oil, such as steam in.ection. cyclic steam stimulation. in.situ combustion. an. steam-assisted g.avity drain.g.. Thermal techn.log.es face n.merous obstacles, as they are en.rg. an. water-in.en.ive processes that are n.t en.iron.en.ally frien.ly. The research also presen.s future tren.s in.en.rg.-savin. an. en.iron.en.ally frien.ly techn.ques that en.an.e heavy oil recovery throug. vapor extraction.(VAPEX) steam-solven. hybrid techn.ques, electromag.0}tic en.rg., son.cation. an. n.n.techn.log.. The fin.in.s of this review reported that all the presen.ed techn.ques focus on.how to reduce the oil viscosity an. in.situ upg.ade the crude oil properties. In.turn. these en.an.e both the productivity rate an. oil recovery an. min.mize the production.cost. This article can.be con.idered a comprehen.ive review of thermal recovery methods in.heavy an. extra-heavy oil, in.addition.to screen.n. criteria used for each method.

Photovoltaic (PV) modules ag. with time for various reason. such as corroded join.s an. termin.ls an. g.ass coatin. defects, an. their ag.in. deg.ades the PV array power. With the help of the PV array n.merical model, this paper explores the effects of PV module ag.in. on.the PV array power, an. the power g.in. an. costs of rearran.in. an. recablin. ag.d PV modules in.a PV array. The n.merical PV array model is first revised to accoun. for module ag.in., rearran.emen. an. recablin., with the relevan. equation. presen.ed herein. The updated n.merical model is then.used to obtain.the array powers for seven.differen. PV arrays. The power results are then.an.lysed in.view of the attributes of the seven.PV array examples. A g.idin. method to recommen. recablin. after rearran.in. ag.d modules is then.proposed, leadin. to further sig.0}fican. power g.in., while elimin.tin. in.ra-row mismatches. When.certain.con.ition. are met, it was shown.that recablin. PV modules after rearran.in. them may lead to further sig.0}fican. power g.in., reachin. 57% an. 98% in.two con.idered PV array examples. Hig.er g.in. are possible in.other arrays. A cost-ben.fit an.lysis weig.in. an.ual power g.in. versus estimated recablin. costs is also g.ven.for the seven.con.idered PV array examples to g.ide recablin. decision. based on.techn.cal an. econ.mic merits. In.the con.idered examples, recablin. costs can.be recovered in.g.d arrays, power g.in. due to our proposed rearran.in. an. recablin. the PV arrays ran.ed between.73% an. 131% in.the con.idered examples-well over the g.in. reported in.the literature. Moreover, the cost of our static module rearran.emen. an. recablin. method outshin.s the costs of dyn.mic recon.ig.ration.methods recen.ly published in.the literature.

Recen.ly, most wave en.rg. research has targ.ted sea areas with hig. power den.ity un.er extreme wave con.ition. for deploymen.. This tren. often.leads to hig.er en.rg. costs for wave power plan.s. However, man. marin. areas with low power den.ity, characterized by wavelet con.ition. an. less destructive forces than.extreme wave con.ition., remain.un.erexplored. Therefore, this study aimed to propose a wave-activated body model for sea reg.on. with wavelet con.ition..
