Mine site Introduction
Located in Gongguan Mining Village, it is the birthplace of petroleum in Taiwan. The earliest discovery of oil in Taiwan was in the 22nd year of the Qing Jiaqing period (1813), at the site of the "Chuhuangku Pit No. 1 Well," about eighty meters in front of the main entrance of the Chuhuangku Pit. This was the first well drilled by the Japanese, and due to the rich oil reserves at Chuhuangku, they drilled a total of 99 wells. The name "Chuhuangku" originated when locals discovered a sulfur-colored liquid gushing from underground, not realizing it was crude oil, and thus named it "Chuhuangku" (Sulfur Outflow Pit). Chuhuangku is the earliest and most important oil mining site in Taiwan, geologically belonging to the anticline structure, with the highest point in the center and slopes towards both sides, where oil and gas are trapped within the anticline structure, extracted through oil wells. The wings of the Chuhuangku anticline are composed of alternating layers of soft and hard sandstone and shale. The geological structure, stratigraphy, and paleobiological studies in this area make it a typical region in Taiwan, essential for geology students to visit! The China Petroleum Company has marked the geological rock layers of the Houlung Creek Valley in the southern part of our town along the roadside, making it a great venue for outdoor geological teaching. The mining area of Chuhuangku is brightly lit at night, incredibly beautiful with the farm on the left, and is also known as the "Night Hong Kong."
