PDC bit loo isticmaalo sahaminta juqraafiga, horumarinta saliida iyo gaasta, qodista ceelasha biyaha, godadka qarxinta iyo samaynta godadka sahaminta seismic, injineernimada dhismaha. hadda waxaa jira 2 nooc: Matrix iyo Jirka Birta.
Qalabka wax lagu dubo ee PDC waa walxo aad u adag oo lagu daray dheeman iyo daawaha adag ee hoos yimaada heerkulka sare.Ma aha oo kaliya inay leedahay faa'iidooyinka adag oo adag oo ka yimaada dheeman, laakiin sidoo kale waxay leedahay faa'iidooyinka iska caabbinta saameynta sare iyo daab weyn oo ka soo jeeda daawaha adag.Waxay si weyn u wanaajisaa waxtarka qodista waana tan ugu habboon ee hawsha qodista ee dhexdhexaadka ah & adag iyo sidoo kale dhagaxa adag ee aad u adag.
Qaab dhismeedka goynta waa xoog isku dheeli tiran, daab yarna si asymmetrical ah ayaa loo qaabeeyey si culeyska saaran uu isu dheellitiro taas oo keeneysa xasillooni wanaagsan oo xoogaa ah.
Gooyeyaasha ugu muhiimsan waa kuwa wax qabadkoodu sareeyo ee PDC si ay u caymiyaan nolosha adeegga xoogaa inta ay hagaajinayaan ROP.
Soo-gaadhista gooyuhu waa la hagaajiyay si loo hubiyo in xoogaa saliidda ahi uu gaadhi karo ROP sare waa qaab-dhismeedyo jilicsan ama dhexdhexaad ah
Qalabka shoogga waxaa loogu talagalay inay ka dhigaan xoogaa awood u leh inay qodaan iyada oo loo marayo qaabab leh qalab adag
Nidaamka Hydraulic ee xoogaa ayaa la hagaajiyay iyadoo la adeegsanayo tignoolajiyada jilitaanka socodka dhaqdhaqaaqa firfircoon si kor loogu qaado nadiifinta iyo qaboojinta saameynta xoogaa si wax ku ool ah looga ilaaliyo xoogaa kubbadda
