Slick Non-Mag Drill Collar
Slick Non-Mag Drill Collar wuxuu bixiyaa culeyska loo baahan yahay xoogaa, mana faragelin doono awoodda qodista jihada.
Spiral Non-Mag Drill Collar
Spiral Non-Mag Drill Collar waxaa loogu talagalay inay oggolaato aagga qulqulka badan ee dareeraha qodista, iyadoo la siinayo faa'iidooyinka birta aan magdhowga ahayn ee barnaamijyada qodista adag.
Flex Non-Mag Drill Collar
Flex Non-Mag Drill Collar waa ka khafiifsan yahay oo ka dabacsan yahay qoorleyda layliga caadiga ah. Awoodda ay u leeyihiin in ay rogrogaan radius gaaban, u foorarsadaan xaglaha dhismaha sare, oo ay dhex maraan doglegs daran waxay ka dhigtaa mid ku habboon isticmaalka jihada iyo codsiyada toosan. Lagu soo saaray bir aan mag-gaab ahayn, kuleelahan daloolista ayaa si fiican ugu habboon guryaha qalabka MWD.

Xasijiye isku-dhafan oo aan magnet-ka ahayn ayaa laga sameeyay hal abuur adag oo bir aan magnetic ahayn. Maaddadu waa nadiif sare oo Chromium Manganese Austenitic ahama.
Kormeerka Ultrasonic iyo MPI waxaa lagu sameeyaa mid kasta oo been abuur ah in ka badan dhererkiisa oo dhan iyo qaybtiisa, ka dib mashiin qallafsan sida ku cad API Spec 71. Shahaadooyinka tijaabada Mill oo ay ku jiraan sifooyin makaanik, falanqaynta kiimikaad, sifooyinka magnetic iyo kormeerka waxaa la siiyaa dhammaan xasiliyayaasha.
Waxaan leenahay awooda aan ku soo saarno Xasilinta Aan Magnetic ahayn ilaa Crown OD 26''

Aan Magnetic MWD Subka ahayn waxaa laga sameeyaa Chromium Manganese Austenitic ahama, tuubada iska caabinta cadaadisku waxay ka samaysan tahay alaab aan ahayn rakibida MWD gudaha iyo kuwa kaleba. Sub Magnetic MWD waxaa si weyn u isticmaalay shirkadaha qodista jihooyinka gudaha iyo kuwa caalamiga ah.
Xidhiidhada oo dhan waxaa loo farsameeyay si waafaqsan API Spec.7-2 iyo xididdada duntu waa qabow la shaqeeyey oo lagu dahaadhay iskudarka dunta API oo lagu qalabeeyay difaacyo.
