What you will learn
Learn how to confidently forecast oil and gas production using proven industry techniques such as PTA, RTA, and Decline Curve Analysis. This course teaches how to estimate reserves, evaluate well performance, and model both conventional and unconventional reservoirs. It includes practical workflows, uncertainty analysis (P10, P50, P90), and real-world case studies to help you apply forecasting methods in real projects.
Description
This course offers a detailed coverage of the industry recognized techniques used to generate production forecasts for oil and gas wells using the applicable techniques; well testing (PTA), Rate Transient Analysis (RTA) and Decline Curve Analysis (DCA). Production forecasting can be more reliable with the knowledge of the OOIP and OGIP; except for DCA, which is achieved using the P/Z plot and PTA for conventional reservoirs. For unconventional reservoirs RTA is utilized using techniques such as the flowing material balance, Rate normalized and type curve methods. Forecasting can readily be performed using Arps decline analysis for conventional reserves (old method) but for the unconventional reservoirs several techniques including: Power Law, Modified Hyperbolic methods. Well Typing is discussed for well with short history but with of offset wells with long history to generate well forecasts. Pressure history matching using either RTA and PTA can allow reliable production forecasts to be generated, which requires both production and pressure data, and also can perform sensitivity analysis for (P90, P50, and P10 cases) using deterministic and probabilistic methods. Other techniques will be discussed for mature waterflood projects using a unique imperial method.
Numerous case studies will be presented using both analytical and
numerical methods. A course hand-out which is an excellent reference will be provided.

Curriculum
Estimate of hydrocarbons-in-place using well test analysis techniques (PTA)
- Review basic concepts of reservoir evaluation, such as flow geometry and boundary conditions.
- Flow regime diagnoses using PTA methods (Log-log plots of pressure vs time and for production rate vs time).
- Review of the principles and applications of the well test analysis techniques to estimate hydrocarbons-in-place, including:
- Reservoir Limit Tests (RLT) – case studies
- Deconvolution techniques – case study
Estimate of the hydrocarbons-in-place using deterministic and probabilistic methods
- Volumetric, static material balance methods (oil and gas), methods (class example)
- Probabilistic method using Monte Carlo simulation
- Use of Rate Transient Analysis (RTA), including:
- Flowing material balance technique
- Advanced type curve matching (Blasingame, Fetkovich)
- Use of history matching techniques of production/pressure data
- Use of new numerical techniques to estimate:
- Stimulated Reservoir Volume (SRV)
- Contacted Reservoir Volume (CRV)
- Forecasting, commonly used for reserves booking of Multi-stage Frac of Horizontal wells (MFHW’s)
- Numerous case studies
Decline Curve Analysis (DCA)
- The use of ARPS decline curve analysis, applications and deficiencies (class example)
- The use of new DCA methods and its application for unconventional wells that are not stabilized (still in transient), including the methods in the graph below
- The use of well typing is discussed to generate production forecasts (P90, P50, and P10 cases)
- A unique empirical (Russian method!) used to estimate recoverable oil and production forecasts for mature waterflood projects – Case studies
- Production forecast for gas wells using the Modified Isochronal test is presented
Target Audience
This course is aimed at reservoir, petroleum and exploitation engineers/technologists, geophysicists, and geologists who are involved in reserves determination and production forecasting.Specification: Oil and Gas Production Forecasting Tools
