Mu gukomeza kwiyongera kw’umutungo ukenewe ku isi, ibikoresho by’amabuye y'agaciro bikora neza kandi bihamye byabaye ingenzi mu kwemeza ingufu n’amabuye y'agaciro. Polycrystalline ya diamant compact (PDC), hamwe nibikorwa byayo byiza, bigenda bisimbuza buhoro buhoro ibyuma bya karbide nkibintu byingenzi mugukuramo umutungo. Agaciro kabo kingenzi kari mubice bitatu byingenzi: iterambere ryikoranabuhanga, imikoreshereze yihariye yo kurwanya imihindagurikire y'ikirere, no guhanga udushya.

Urebye muburyo bwa tekiniki, abakata PDC bageze kuri kwant gusimbuka mubukomere no kwambara birwanya. Gukomatanya munsi yubushyuhe bwinshi hamwe numuvuduko mwinshi uturuka kuri poro ya diyama na karbide substrate, baragwa ubukana bukabije bwa diyama (hejuru ya HV10.000) mugihe bagumana ingaruka zikomeye za karbide. Ibi bikemura ikibazo gihura nabakata gakondo: gukomera gukomeye kuganisha ku buryarya, mugihe gukomera gukomeye biganisha ku kwambara. Mu bucukuzi bwimbitse, ibiti bya PDC, bikorera mu bitare bikomeye nka granite na basalt, byerekana igipimo cyo kwambara kingana na kimwe cya gatanu cy’ibikata karbide, byongera ubuzima bwabo inshuro 3-5. Ibi bigabanya cyane inshuro zo gusimbuza ibice munsi yubutaka kandi bigabanya ibyago byo guhagarika ubucukuzi. Kubijyanye no guhuza n'imihindagurikire y'ikirere, uburyo bwinshi bwo gukata PDC bwujuje ibyifuzo bitandukanye byo gukuramo umutungo. Mu gucukura peteroli na gaze, impande zabo zikata zisenya vuba vuba urutare. Umwirondoro wamenyo yihariye (nka wedge na shusho yikiyiko) uhuza inzira zinyuranye za wellbore, byongera imikorere yo gucukura mumariba atambitse kandi yerekeza hejuru ya 40%. Mu bucukuzi bw'amakara, imashini ya PDC idashobora guhangana n’ingaruka zihanganira ingaruka zikomeye ziterwa n’amakara, birinda kuvunika amenyo no gukomeza gukora ibikoresho by’ubucukuzi bwuzuye. Mu bucukuzi bw'ibyuma, imashini ya PDC ifite ibishishwa birwanya ruswa irwanya isuri ituruka ku mazi acukura acide, bigatuma bikenerwa haba mu bucukuzi bw'amabuye y'agaciro ndetse no mu kuzimu mu bidukikije bigoye bya geologiya.

Urebye mu nganda, abakata PDC bagize uruhare rutaziguye mu kugabanya ibiciro no kuzamura imikorere mu gukuramo umutungo. Ku ruhande rumwe, igihe kirekire cyo kubaho kigabanya ikiguzi cyo kugura no gusimbuza ibikoreshwa. Kurugero, mugucukura peteroli, ikiguzi cyo gutema iriba gishobora kugabanukaho 20% -30%. Byongeye kandi, imikorere yabo myiza yo kugabanya igabanya ubucukuzi bwamabuye y'agaciro. Kurugero, nyuma yo gufata amashanyarazi ya PDC, ikirombe kinini cyamakara cyongereye amashusho yabyo buri munsi kuva kuri metero 80 kugera kuri metero 120, byongera umusaruro wumwaka 15%. Byongeye kandi, imyambarire mike yimyenda ya PDC igabanya kubyara no koroshya ibikorwa byogusukura umwobo, kuzamura umutekano wubucukuzi butaziguye.

Mugihe gukuramo umutungo bigenda byiyongera no muburyo bugoye, ubwihindurize bwikoranabuhanga bwibikoresho bya PDC bikomeje kwihuta. Mu bihe biri imbere, mu kongera ubushyuhe bwo hejuru cyane binyuze mu ikoranabuhanga rya nano-coating no kunoza imiterere yo gutema hifashishijwe icapiro rya 3D, imashini ya PDC izarushaho kunesha imikorere, itanga inkunga ikomeye yo guteza imbere umutungo utoroshye wo gukuramo nka gaze ya shale hamwe n’amabuye y'agaciro yo mu nyanja, ndetse no kurushaho gushimangira umwanya wabo w'ingenzi mu gucukura umutungo.
