摘要

增加油氣產量，為各國重視課題。油氣資源可分為傳統與非傳統油氣資源。由於傳統油氣資源逐漸耗竭，且非傳統油氣具有分布範圍廣泛及經濟規模大的性質，因此非傳統油氣資源逐漸成為油氣開採的趨勢。要進入非傳統油氣礦區，須了解非傳統油氣礦區特性，才能找到有利於投資的非傳統油氣礦區，增加自有油氣產量。在本研究中，篩選四個指標（Indicators）可供評估水平液裂井最終可採量（Estimated ultimate recovery, EUR）之用，並實際評估KOC位於美國德州非傳統油氣礦區，評估結果EUR為11至17萬桶油之間，此案於目前低油價可能無法回本，或是在未來油價較高或EUR產能較高，或鑽井成本較低時，才有機會達到公司開發階段門檻，但在現今條件下，因不符成本，故不建議投資。

Every country must have a sustainable oil and natural gas supply. Although some alternative energes have been exploited, they are not adequate to substitute for oil and natural gas energy. As the conventional oil and gas resources are being depleted, we need to look for unconventional oil and gas resources. Oil and natural gas resources can be divided into conventional and unconventional resources. The unconventional resources have been discovered and some have been recovered economically in the past decades. The unconventional oil and gas resources are the main target for current oil and gas exploration. In this study, four indicators were selected to evaluate the estimated ultimate recovery (EUR) of horizontal wells from unconventional oil and gas reservois. We developed a procedure to evaluate the unconventional oil and gas resources of KOC in Texas, USA. The EUR of oil from KOC estimated was 110,000 to 170,000 BBLs. Current low oil price makes the investment in KOC economically infeasible.
