The new numbers for the Marcellus Shale and Point Pleasant-Utica Shale represent large increases from previous USGS assessments of both formations. Production and proved reserves in the Permian Basin’s Wolfcamp Shale and Bone Spring Formation are reaching new heights, and a new assessment from the US Geological Survey indicates the industry is just scratching the subsurface when it comes to what may be technically recoverable. Major oil discoveries by Armstrong Oil & Gas and ConocoPhillips have compelled the US Department of the Interior to reassess its estimate of undiscovered, technically recoverable resources in parts of Alaska. The list of the biggest gas plays in the US is being revised as the US Geological Survey creates new estimates based on additional drilling results and available rock samples. New at Number 2 is the Mancos Shale on the Western Slope of the Rockies with 66 Tcf in recoverable reserves.
Noble’s first row of wells in its massive Mustang project is helping increase the operator’s DJ Basin output, and similar results are soon expected in the Delaware Basin. Proved oil and gas reserves in the US have spiked to levels not seen before, the EIA reports, and one of the main drivers is the Permian’s Wolfcamp-Bone Spring Shale.
Estimates derived under these definitions rely on the integrity, skill, and judgement of the evaluator and are affected by the geological complexity, stage of exploration or development, degree of depletion of the reservoirs, and amount of available data. Use of the definitions should sharpen the distinction between various classifications and provide more consistent resources reporting. The resource classification system is summarized in Figure 1 and the relevant definitions are given below. Elsewhere, resources have been defined as including all quantities of petroleum which are estimated to be initially-in-place; however, some users consider only the estimated recoverable portion to constitute a resource. In these definitions, the quantities estimated to be initially-in-place are defined as Total Petroleum-initially-in-place, Discovered Petroleum-initially-in-place and Undiscovered Petroleum-initiallyin- place, and the recoverable portions are defined separately as Reserves, Contingent Resources and Prospective Resources.
Petroleum1 is the world's major source of energy and is a key factor in the continued development of world economies. It is essential for future planning that governments and industry have a clear assessment of the quantities of petroleum available for production and quantities which are anticipated to become available within a practical time frame through additional field development, technological advances, or exploration. To achieve such an assessment, it is imperative that the industry adopt a consistent nomenclature for assessing the current and future quantities of petroleum expected to be recovered from naturally occurring underground accumulations. Such quantities are defined as reserves, and their assessment is of considerable importance to governments, international agencies, economists, bankers, and the international energy industry. History and Process The terminology used in classifying petroleum substances and the various categories of reserves have been the subject of much study and discussion for many years.
The committee is responsible for programs dealing with oil and gas reserves and resources matters, including reserves and resources definitions, terms, recommended practices, and standards. The committee disseminates reserves and resources information to other organizations, agencies, and companies involved in reserves matters, including cooperation with other committees and organizations in development and delivery of relevant training courses. The Oil and Gas Reserve Committee (OGRC) typically includes twelve to sixteen SPE members (or more when deemed necessary for special projects or special skill sets) who are degreed engineers and geoscientists with 10-plus years of experience in reserves and resources estimation. Traditionally, members serve three-year terms. In addition to the Society of Petroleum Engineers, other organizations may provide OGRC observers.
Thank you for attending the SPE Workshop. The oil and gas industry is moving towards deepwater exploration as cost optimisation, through a period of low priced oil, has ensured deepwater explorations and production become more viable. Currently, offshore production facilities in Myanmar exists in both shallow and medium water depths; however, the potential of frontier deepwater exploration are available within the Myanmar offshore blocks. This workshop provided a unique platform for industry practitioners and subject matter experts in E&P and operations to discuss opportunities, emerging technologies, holistic approaches to E&P and more. The workshop also provided an insight on how the industry can rejuvenate both onshore production and operations.
Proved oil reserves totaled 43.8 billion bbl at yearend 2018 while proved gas reserves amounted to 504.5 Tcf, both topping records set in 2017, the US Energy Information Administration said. Proved oil and gas reserves in the US have spiked to levels not seen before, the EIA reports, and one of the main drivers is the Permian’s Wolfcamp-Bone Spring Shale.
Two discoveries offshore Mexico add to April’s finding in the Norwegian Sea. The Esox-1 well encountered 58 m of high-quality oil-bearing Miocene reservoirs and will be tied back to Tubular Bells production facilities. The Orca-1 and Marsouin-1 wells have derisked up to 50 Tcf of gas initially in place from the Cenomanian and Albian plays in the BirAllah area, more than sufficient to support a world-scale LNG project, partner Kosmos Energy said. India’s ONGC reported an oil find in Colombia’s Llanos Basin as well as a gas and oil discovery in Brazil’s deepwater Sergipe Alagoas Basin. Development of the Tolmount East discovery will be fast-tracked, the operator said.
This paper presents a methodology that provides the upstream industry with a robust approach to petroleum inventory management. This paper will examine ways in which Chance of Development (CoD) can be defined better, methods for its estimation, and its appropriate application along with common misuses. The implementation of the PRMS has contributed significantly to the understanding of the hydrocarbon-maturation process in the Netherlands. There are no reliable estimates of technically recoverable resources (TRRs) for unconventional reservoirs outside North Amercia, and many countries lack the advanced technology such as horizontal drilling and hydraulic fracturing necessary to develop unconventional resources. The Guidelines for Application of the Petroleum Resources Management System (AG) document was issued in November 2011.
