Shale gas - ọzọ isi iyi nke ike na nsogbu

Shale gas bụ ụdị nke eke gas, ọ na-emi esịnede predominantly nke methane na lekwasị ke shales.

Shale rock na-akpọ ịkpakọba ọtụtụ n'ígwé ẹbiet ka ala-okpomọkụ minerals (chlorite, sericite, actinolite, muscovite et al.).

A nkume e ji mara ike mfe kewaa efere akpụ ohere (anakọta) n'etiti nke accumulates shale gas.

Onye na-anakọta na-bụghị ọgaranya gas mee, ma, o sina dị, ha na-ezu na-ahazi azụmahịa mmepụta.

Shale ego hụrụ na bụla na Afrika, na mba nwere ike ime ka ọ bụla na-abụghị obodo, na-enye ndị dị mkpa ego.

Mmịpụta nke a gas na-eri dị elu n'ihi na eziokwu na mbụ ya e jikọtara ya na nke mbụ nke nnukwu ebe, iji haịdrọlik agbajikwara technology (haịdrọlik esite) na mgbe nile egwu ogologo n'oghere ọnụ ọgụgụ buru ibu, eke na ha a mgbape maka gas pumping.

gas mmepụta

The mbụ azụmahịa mmepụta nke gas si shale ego na United States nwere rụrụ.

Mgbe e mesịrị mma technology, na ijikọta vetikal na kehoraizin egwu, nke belata na-eri nke gas.

Taa shale gas na-emepụta site na-arụ egwu vetikal ma ọ bụ kwụ olulu iji multiotvodov n'otu omimi na multistage olulu (kwụ) na tinyekwa elu atọ kilomita.

Technology-enye shale gas injection olulu gbapuru na a ngwakọta nke mmiri, ájá na ọgwụ. Water hama emee, nke mgbari gas esite mgbidi, nke na-enye ohere ka imipu na n'elu nke niile dị gas.
