Well Testing—Getting the Objectives Right
This course reviews past and current testing methodology applied to conventional and non-conventional reservoirs (shale oil and gas), heavy and extra heavy oil, naturally fractured, carbonates and gas condensate reservoirs located either inland or offshore. Participants will learn that, although current testing practices are carried out using modern testing equipment and high resolution pressure data acquisition system, getting the reservoir evaluation objectives depends on the behavior of the formation fluid properties, well completion, and flow assurance situations which just happen to be known only when testing is carried out, and in many cases have not been anticipated by test design. To get the testing objectives right, testing program changes need to be done during the progress of the test which are based on well pressure and production data analysis. Based on field experience there is always a risk of not getting evaluation objectives at all or an equally worst testing scenario where the obtained evaluation results are subject to discussion.
- Well testing – why and when is needed
- Conventional and non-conventional reservoirs
- Hydraulically Fractured Horizontal Wells
- Heavy and extra heavy oil reservoirs
- Carbonates and fractured reservoirs
- Gas-condensate reservoirs.
- Testing management
- Flow assurance
- Management of contingencies
There are many reservoir and flow assurance situations when testing the well which have not been anticipated by test design. This course will make you aware that in order to get testing objectives right, appropriate management of contingencies during testing which are based on pressure and rate data analysis is needed in most cases.
Who Should Attend
This course is for petroleum, reservoir and production engineers, as well as testing managers.

Giovanni Da Prat is the president of DA PRAT consulting, an independent international oil and gas consulting firm. He has more than 32 years of experience in the oil and gas industry, primarily dedicated to testing management, pressure transient analysis and nodal analysis. Da Prat’s experience besides 14 years as the president of DA PRAT consulting, includes nine years as a reservoir engineer for Schlumberger where he designed and interpreted testing data including data from formation testers acquired from wells located in Venezuela, Colombia, Peru, Ecuador, Bolivia, Brazil, and Argentina fields. He also spent three years with Halliburton as the regional reservoir engineer in charge of DST testing design and interpretation for South America oil and gas fields.
Da Prat has been the author and coauthor of numerous SPE technical articles, and he wrote the book, Well Test Analysis for Fractured Reservoir Evaluation, published by Elsevier in 1990. He was an SPE Distinguished Lecturer in 2003–2004. Da Prat holds an MS in geophysics (1977) and a PhD in petroleum engineering (1981), both from Stanford University.
