We are grateful to our generous sponsors for their assistance in building and supporting PetroWiki. SPE-99971-MS. http://dx.doi.org/10.2118/99971-MS. Gringarten, A.C. 2010. Outcomes of a well test, for instance flow rate data and gas oil ratio data, may support the well allocation process for an ongoing production phase, while other data about the reservoir capabilities will support reservoir management. The reservoir model is further developed to support the field development planning and to advise for the optimal location for extra production wells to be drilled. These tools include RFT, MDT, etc. Contamination may also be removed and fluid samples collected. Reservoir engineers in large oil companies, data interpretation engineers in well testing service companies, evaluation engineers in acidizing and fracturing companies, graduates or undergraduates as reference book, and oil engineers as skill training materials.

To obtain individual well flow rates, it is common to use a smaller test separator. Effect of Scaleup and Aggregation on the Use of Well Tests To Identify Geological Properties. SPE-77452-PA. http://dx.doi.org/10.2118/77452-PA. Wei, L., Hadwin, J., Chaput, E., et al. [4] This is generally taken into account by the allocation of products back to individual wells based on the field total, and by using data from the individual well tests. In 1980s took charge and operated interference tests and pulse tests in an oilfield in carbonate reservoir successfully; during this period he invented the interpretation type curves for interference well test in dual porosity reservoirs and applied these type curves in field practice; took charge of research of downhole differential pressure gauge and applied these gauges in data acquisition in fields and consequently won the invention award from China Nation Science and Technology Committee and was present the First International Meeting on Petroleum Engineering in Beijing in 1982and his paper was published in the JPT. Since 1990 he served Research Institute of Petroleum Exploration and Development of CNPC, was concerned with the exploration and development of several large- or medium-scale gas-fields in China and has been doing dynamic performance research in about recent 20 years.

Shut in the well till pressure reaches static level and then flowing the well at a constant rate ,q & measuring Pwf.

He participated in the exploration and development of several large- and medium-scale gas fields in China and completed more than one thousand gas well intervals dynamic performance study over the past 28 years.

To perform a well test successfully one must be able to measure the time, the rate, the pressure, and control the rate. Presented at the SPE Eastern Regional Meeting, Lexington, Kentucky, USA, 3-5 October.

Now is serving SPT Energy Group Inc. as its chief geologist. Applied well test interpretation. In the petroleum industry, a well test is the execution of a set of planned data acquisition activities. SPE-161000-MS. http://dx.doi.org/10.2118/161000-MS. Bourgeois, M., and Couillens, P. 1994.

Test objectives will change throughout the different phases of a reservoir or oil field, from the exploration phase of wildcat and appraisal wells, through the field development phase and finally through the production phase, which may also have variations from the initial period of production to improved recovery by the end of the field lifecycle time. There are many flavours of well tests and various ways to categorize test types by its objectives, however two main categories only by objectives, these are productivity tests and descriptive tests. Discriminating Fracture Patterns in Fractured Reservoirs by Pressure Transient Tests. Multiphase flow meters have to some degree reduced the need for flow tests and test separators. A DST is used to obtain reservoir fluid samples, static bottomhole pressure measurements, indications of productivity and short-term flow and pressure buildup tests to estimate permeability and damage extent. Multi-point tests are used to establish gas well deliverability and absolute open flow potential. Dr. Hedong Sun received his PhD degree from Xian Jiaotong University in 2004. Well testing.

This is the most preferred well testing technique. Well test analysis in tight gas reservoirs.

Dynamic Well Testing in Petroleum Exploration and Development, Second Edition, describes the process of obtaining information about a reservoir through examining and analyzing the pressure-transient response caused by a change in production rate. SPEBookstore or WorldCat, Lee, J. Single-point tests typically involve a measurement or estimate of initial or average reservoir pressure and a flow rate and flowing bottomhole pressure measurement. WorldCat, Earlougher, R.C. Flexible - Read on multiple operating systems and devices. According to The Lease Pumpers Handbook of Oklahoma Commission on Marginally Producing Oil and Gas Wells, there are four basic well test types: potential tests, daily tests, productivity tests, and gas oil ratio tests,[2] the latter three in the broader productivity test category. Senior Reservoir Engineer of the PetroChina Research Institute of Petroleum Exploration & Development (RIPED) and Deputy Director of the Department of Gas Field Development, China testing types manual software qa test methodologies automation different various application process tester difference between techniques 360logica end under softwaretestingclass Flow rate, water cut, GOR and other parameters for the test system can deviate from production separators.

A production test is just like a drawdown test, except that it is generally run for a longer period of time. https://petrowiki.spe.org/w/index.php?title=Well_test&oldid=54181, Copyright 2012-2022, Society of Petroleum Engineers, Evaluating the well permeability and skin effect.

He holds a BS degree in Reservoir Engineering from Daqing Petroleum Institute of China, MS and PhD degree in Reservoir Engineering from China University of Geosciences (Beijing).

Identifying heterogeneities and boundaries.

We are always looking for ways to improve customer experience on Elsevier.com. melvi todd student arc Data gathered during the test period includes volumetric flow rate and pressure observed in the selected well. The well is first produced at a constant rate till pressure is stabilized and then the well is SPE-28899-MS. http://dx.doi.org/10.2118/28899-MS. Cramer, R., Jakeman, S.V.J., and Berendschot, L. 2006. 2013. 2013. SPE disclaims any and all liability for your use of such content. Often, and especially at offshore fields, a number of wells produce to a common separator, and flows from several separators or facilities may be headed into a commingled flow in pipeline that transports oil or gas for sale (export). Locating Closed Perforations and Damaged Sections Using Well Test Analysis.

1982. Theres no activation process to access eBooks; all eBooks are fully searchable, and enabled for copying, pasting, and printing. Pressure transient testing. Use of Well Test Analytical Solutions for Production Prediction. Another method[5] to obtain individual well flow rates takes the state observer approach, where the states to be estimated as the unknown flow rates from individual wells. Her focus is combining well short term PBU with long period performance and geology to propose production optimization. Information from well tests will supplement the amount of information with flow rate data, pressure data, and other, which is needed to build a rich reservoir model. Most well tests consist of changing the rate, and observing the change in pressure caused by this change in rate. Sign in to view your account details and order history.

The test will also provide information about the state of the particular well used to collect data. Dallas: Society of Petroleum Engineers of AIME. Some flow tests, such as drill stem tests (DSTs), are performed in the open hole.

To check pressure equilibrium and thus homogeneity wells can be tested using wireline-conveyed tools, either in casing or open-hole.
