Reservoir quality database enhanced prediction

项目摘要

As we explore for deeper and hotter oil and gas reservoirs, the quality (porosity and permeability) of the host reservoir rock becomes ever more critical, since burial and heating typically lead to extreme degrees of compaction and mineral cement growth (these are collectively known as diagenesis). There is no universal way of predicting sandstone reservoir quality, especially in high-pressure and high-temperature settings, so that this aspect of oil and gas exploration is becoming increasingly critical. As well as ultimately producing an invaluable tool to help exploration, it is expected that this research will result in new insights and conclusions about the origin and distribution of the controls on sandstone reservoir quality deep in sedimentary basins.This research is designed to collect published data on sandstone oil and gas reservoir quality, dispersed over the world's literature in book-chapters, journals and published government archives, into a relational database. The database will contain porosity and permeability data and information on the age, depth, temperature and type of sedimentary rock. Most crucially, it will contain data on the fundamental characteristics that control reservoir quality; the mineralogy and texture of the original sand grains, type and quantity of mineral cements and the quantity of clay matrix.This task is substantial but not impossible; in the one year initial project it is proposed that the database-build is restricted to UK basins and neighbouring areas (Norwegian sector of North Sea, Irish territorial waters). The ultimate goal is to capture all relevant published data for all sedimentary basins on Earth.This database will help oil and gas exploration companies predict sandstone reservoir quality, and so reduce risk, by allowing explorers to find appropriate analogues. The database will help to extend the life of mature basins within UK territories and should help exploration and exploitation in challenging high pressure and high temperature environments such as the areas west of the Shetland Islands. It is expected that there will be an ever-increasing demand for this type of knowledge.End-user organisations (oil and gas exploration companies: BG, BP and Nexen) have been involved in the inception and design of this research initiative and will be consulted extensively at the outset of the work to ensure that the database design is fit for purpose. The research will involve two-week visits to BG, BP and Nexen in order to input proprietary data into the database. This will demonstrate its potential to be an industry standard for reservoir quality prediction.During the project a formal proposal for a Joint Industry Programme (JIP), to continue this work, will be prepared and circulated to all oil and gas exploration companies. A workshop will be held at Liverpool University, towards the end of this short project, to promote the Reservoir Quality Database to all interested oil and gas exploration companies. The workshop will promote the JIP to sustain and continue this work.As part of the new JIP, oil and gas companies will be invited to develop company-specific, proprietary versions of the Reservoir Quality Database, fully compatible with the open-access version, since these companies do not typically systematically archive their own data. They will be invited to have data from current or ongoing projects archived as well as older data, in order to ensure maximum impact of historical exploration and oil field appraisal activities.The output from this initial phase of the work will be presented at a major petroleum geology-focussed conference and submitted as a paper to an international journal. It is expected that this unique collation of sandstone reservoir quality data will lead to a new perspective on compaction and cementation and so result in new research initiatives, both at Liverpool and possibly within oil and gas exploration companies.

随着我们勘探更深、更热的油气藏，宿主储集岩的质量(孔隙度和渗透率)变得越来越关键，因为埋藏和加热通常会导致极端程度的压实和矿物水泥生长(这些统称为成岩作用)。目前还没有通用的方法来预测砂岩的储集层质量，特别是在高压和高温环境下，因此这方面的油气勘探变得越来越关键。除了最终产生一个无价的工具来帮助勘探，预计这项研究将产生关于沉积盆地深处砂岩储集层质量控制的起源和分布的新见解和结论。这项研究旨在将散布在书章、期刊和出版的政府档案中的有关砂岩油气储集层质量的公开数据收集到一个关系数据库中。该数据库将包含孔隙度和渗透率数据以及关于沉积岩的年龄、深度、温度和类型的信息。最重要的是，它将包含控制储集层质量的基本特征、原始砂粒的矿物学和结构、矿物胶结物的类型和数量以及粘土基质的数量的数据。这项任务是艰巨的，但并非不可能；在为期一年的初步项目中，拟议的数据库建设仅限于英国盆地和邻近地区(北海挪威部分、爱尔兰领水)。最终目标是获取地球上所有沉积盆地的所有相关公开数据。这个数据库将帮助石油和天然气勘探公司预测砂岩储层质量，从而通过允许勘探者找到合适的类似物来降低风险。该数据库将有助于延长英国领土内成熟盆地的寿命，并应有助于在具有挑战性的高压和高温环境中进行勘探和开采，例如设得兰群岛以西地区。预计对这类知识的需求将不断增加。最终用户组织(石油和天然气勘探公司：英国天然气集团、英国石油公司和尼克森公司)参与了这项研究计划的初始和设计，并将在工作开始时广泛咨询，以确保数据库设计符合目的。这项研究将对英国天然气集团、英国石油公司和尼克森公司进行为期两周的访问，以便将专有数据输入数据库。这将证明它有潜力成为储层质量预测的行业标准。在项目期间，将编制一份关于继续这项工作的联合行业计划(JIP)的正式提案，并将其分发给所有石油和天然气勘探公司。在这一简短项目接近尾声时，将在利物浦大学举办一次研讨会，向所有感兴趣的石油和天然气勘探公司推广储层质量数据库。作为新的联合执行计划的一部分，将邀请石油和天然气公司开发针对公司的、与开放获取版本完全兼容的储集层质量数据库的专有版本，因为这些公司通常不会系统地将自己的数据存档。他们将被邀请将当前或正在进行的项目的数据以及较旧的数据存档，以确保历史勘探和油田评估活动的最大影响。这项初步工作的成果将在一个以石油地质学为重点的主要会议上提交，并作为论文提交给一家国际期刊。预计这种对砂岩储层质量数据的独特整理将导致对压实和胶结作用的新视角，从而在利物浦和可能在石油和天然气勘探公司内产生新的研究举措。
