Zoram chhuah chhoh chang hian, zokhua lama awm kan chhungte thenkhat hian, Oil company a thawk ka nih hria in, Khawnvartui sema thawk turah ngar ngar min lo ngai a, engemaw zawng tak chuan a nuihzat thlak ang reng hle a, mahse, anin Oil Company a la hmuh chhun kha chu Petrol Pump ka a nih mai hmel a, a awm viau tho mai. Kan hnathawhna lam hi luhchilh lem lo tan chuan a lo hriat loh theih viau mai dawn a lo ni a. A tawi kim thei ang bera sawi kan tum a nge.

Ka thawhna company hna ber chu Oil leh Gas zawn chhuah, verh, tharchhuah leh pipeline a thawn darh a ni a, a zawnchhuah lam leh a verh lam hi ka hna a nih loh avangin sawi tur ka hre tlem khawp mai. Chuvang chuan keima’n a ka thawh ve chin hrim hrim hi sawi ila, sawi sual a tlem deuh vang chu. Production Gas department ah 1996 atang khan ka thawk ve tan a, Production engineer post a lut ni mahila, kan hna erawh a tam zawk chu Mechanical engineering lam a ni. Tun hnu hian Production lam hi kan khawih ve ta chauh tih mail oh chu.

Oil leh Gas zawnchhuah, verh a nih hnu hian lei chhungril (km 4 -7 thlenga thuk te pawh a ni thei) atanga lak chhuah leh kha khur atanga rawn chhuak, tui, oil leh gas te then hran kha production hna chu a ni tlangpui awm e. A chipchiar chuan well completion (Lei chhungril lama hmanrua kan hman etc) chu ni danga sawiah khek phawt ila, kan thu a sei lutuk loh nan.

Natural Gas chu enge? : Leilung inthlak danglam velin a siam, lei chhungrila gas awm hi Natural Gaas kan tih chu a ni mai a, chemistry lam te kan tui viau anih chuan Hydrocarbons te ti ila, a fiah deuh awm e.

Chung well fluids te then hran an nih hnu chuan then hran dan azir khan gas pawh Thuang hnihin kan hmu / dawng tihna a nih chu. HP gas leh LP Gas tiin. Chung gas thenhran tawh ho lo enkawl chu kan hna a ni. Chung gas te chu keinin Pipeline bawkin Gas Compressor Station ah kan la a. LP Gas hi a pressure a tlem avangin hmanna a tlem hle mai a, hmun hla-ah a thawn theih loh avangin HP gas ah siam a ngai thin. Chu chu compressor hmangin HP Gas ah kan siam thin, Chumi compressor chu Low Pressure Booster (LPB) kan ti. Ni khatah gas 5000000 Cubic Feet kan LPB hian a compress thei, kan compress hma hian gas a bawlhhlawh leh tui awm te pawih chhuah nan Knock Out Vessels leh Mist Extractor kan kaltlang tir phawt thin.
