Ezinkampanini ezibandakanyeka ochungechungeni lokuhlinzekwa kokuqhekeka, njenge-河北凯源石油支撑剂有限公司, le yindawo eguquguqukayo futhi ezuza kakhulu efuna ukufunda okuqhubekayo, ukuzivumelanisa, nokutshalwa kwezimali ezingeni eliphezulu nasekuzinzeni.

Ngokufingqa, i-hydraulic fracturing ubuchwepheshe obuzohlala buyingxenye ebalulekile yengxube yamandla emhlabeni iminyaka eminingi ezayo, noma ngisho nomnotho womhlaba ushintshela emithonjeni yamandla ehlanzekile futhi ehlukahlukene. Izinto ezibalulekile ezithathwe kulesi sihloko yilezi: i-hydraulic fracturing inqubo eyinkimbinkimbi kodwa eqondwa kahle esebenzisa ukusebenzisana okuhlangene kwezinto eziwuketshezi, ama-proppants, kanye ne-rock mechanics; izinzuzo zezomnotho nezokuphepha kwamandla zinkulu futhi ziyaziwa kabanzi; izimo zamanje zibheke ekusebenziseni ugesi, ukubeka idijithali, nokusimama; futhi ikusasa libambe amathuba ajabulisayo okwandisa ubuchwepheshe bokuhlukanisa ezindaweni ezintsha ezifana ne-geothermal nokugcinwa kwekhabhoni. Ngokuhlala unolwazi ngalezi zenzakalo nokusebenzisana nabahlinzeki abathembekile njengoHebei Kaiyuan Petroleum Proppant Co., Ltd. (IKHAYA), amabhizinisi angazula ezindaweni eziguqukayo zokuhlukumeza ngokuzethemba. Sikhuthaza abafundi ukuthi bahlole izinsiza ezitholakala kuwebhusayithi yenkampani ukuze bafunde kabanzi ngohlu lwemikhiqizo yabo olubanzi, izinketho zezinsizakalo ezenziwe ngendlela efanele, nokuzibophezela ekugqamaleni ekukhiqizeni i-proppant. Uhambo lwe-hydraulic fracturing alukapheli—ilungena esahlukweni esisha sokusungula amathuba, futhi labo abayemukelayo bazoba sesikhundleni esihle sokuphumelela.
