綠龍公司是格瑞克（中國）的母公司，致力于在中國境內專業從事天然氣產業。綠龍公司在中國的經營活動是以其子公司格瑞克的名義開展的。
作為一家外資燃氣供應商，綠龍公司專注于煤層天然氣（俗稱為煤層瓦斯或煤層氣）的勘探、開發、生產與銷售。公司旨在不斷強化其垂直一體化的綜合開發程度。
格瑞克（中國）是中國境內煤層氣勘探開發的先鋒，它在山西、江西、安徽和貴州等6個項目（總面積7589平方公里，預測氣體儲量22萬億立方英尺）擁有自有煤層氣氣源。采出氣體后，公司以CNG壓縮天然氣為主，PNG管道天然氣為輔的方式將之銷售給市場用戶。
在中國，格瑞克公司與中聯煤層氣有限責任公司（一家國有煤層氣公司）通力合作，旨在發展壯大我們自有的煤層氣儲備，并遵循與其簽訂的產品分成合同，享有開發項目的開采權。
格瑞克（鄭州）煤層氣技術服務有限公司，作為鉆井平臺的分支，是位于鄭州的整個格瑞克公司上游業務的運營中心。公司已從美國進口了五臺鉆機并聘請了150位專業技術人員，且已有效的規避了各種鉆井成本提高的風險。目前格瑞克（鄭州）煤層氣技術服務有限公司的各臺鉆機及技術人員已完全到位。
格瑞克制造公司則是一家頗具效益的CNG加氣機、站點及相關服務的供應商。本公司生產的加氣機為“CLEAN”牌，目前生產能力為300臺以上，今后，將隨著中國市場需求的增加而提高。
格瑞克信息技術服務公司是一家致力于小生境技術的供應商，產品主要包括石化行業專用的各種專利軟件、監控及信息采集系統。公司設計研發的各種軟件滲透于格瑞克上游鉆井及采氣、中游氣體壓縮及運輸、下游天然氣銷售及現金收款等各個環節。
格瑞克運輸及基建，在當前中國天然氣市場需求不斷增長的環境下，一個全面一體化的企業應不斷提高其團隊協作程度并增強其抓住市場機遇的能力。為實現我公司中游優組協作方案，我們計劃開展的物流業務，以便將本公司的煤層氣產品輸送給相關客戶。
格瑞克天然氣銷售公司是致力于CNG壓縮天然氣氣站開發及運營的公司，它將協助山西柿莊南煤層氣生產區塊和近收購的鄭州燃氣銷售中心為公司創造效益。
