Talu ai nei, o le Roteri steerable PDC laʻititi ma downhole afi tutoʻatasi atinaʻeina e la matou kamupani ua maeʻa lelei faʻatasia ma le faʻaulu mai o rotary steerable mea faigaluega i le tolu avanoa matala ma faʻavaega vaieli vaega Wei202H2-10 (2936-4237m, Longmaxi faʻavae) viliina e le 'au 50022 o Great Wall Drilling Company. Ua ausia le faamoemoe faamoemoeina ma maua autasi viia e viliina kamupani ma faatonuga kamupani kamupani.

O le rotary steerable PDC bit and downhole motor viliina i lalo faalua i le vavave faʻateleina vaega, ma le aofaʻi o ata o 1,301 mita, o 700 mita na viliina faʻasolosolo. O le aofaʻi o taimi e viliina ai le 117 itula, o le aofaʻi o le sikurini faʻaaoga taimi e 229 itula, ma le averesi o le sao i totonu o le 11.12 mita i le itula. O se faʻaiuga o le suia o metotia masani o le toso mai i fafo ao faʻagaoioiga viliina, o le faʻaaogaina laititi o 95% o le muamua fou laʻititi.

O le Roteri uli uli PDC o se fou fou ituaiga o laʻitiiti faʻapitoa atiaeina e la matou kamupani mo fetuʻutuʻunaina faʻasolosolo tiʻetiʻe mea faigaluega ma faʻavili faʻasolosolo tiʻetiʻe i lalo afi e faʻafetaui ai manaʻoga o shale kasa atinae ma faʻavae faapitoa. Lenei ituaiga o laʻitiiti tuʻufaʻatasia ma la tatou tutoʻatasi atamai meatotino aia tatau o tuusaʻo faigofie-ia-faʻatonutonu tekonolosi, puipuia si faʻapipiʻi tekinolosi, Faʻaleleia atili tekonolosi ma vaʻaia maualuga-faatinoga PDC Cutters. E i ai uiga o le lelei azimuth pulea, maualuga rotary saosaoa, leai se paʻu, fale o manu faʻagaioiga ma umi auaunaga ola ao viliina.

O le alualu i luma manuia ma le faʻaogaina o le rotary steerable PDC laititi ma lalo o le afi o se tasi sili taua ausia o la matou kamupani i le tutoʻatasi suʻesuʻega ma atinaʻeina o mea viliina meafaigaluega. O lona faʻalauiloaina ma le faʻaogaina e mafai ona suia ai oloa faʻaulufale mai, matua faʻaititia le viliina o tau, ma lona maketi vaʻaiga lautele.
