Reservoir management and production data logging
Course objectives: Students will be able to comment on the fundamentals of reservoir management, present the theoretical production decline curves, evaluate a certain well’s operational conditions and apply the material balance equation.
Course content:
- 1. Reservoir management fundamentals:
- The concept of reservoir management: definition of the term reservoir management, fundamentals of the reservoir management, importance of the geoscience, research and development strategy;
- Consideration of spatial well patterns – four, five, seven, nine spot patterns, including inverse patterns;
- Decision making regarding the implementation of a new recovery method (infill drilling, waterflood, stimulation);
- Collection and analysis of the data: data types, data validation, data storage and withdrawal;
- Management of a geothermal reservoir;
- 2. Theoretical production decline curves:
- Analysis of the reservoir behaviour: primary recovery methods, reserves, volumetric method;
- Exponential, hyperbolic and harmonic decline types;
- Characteristics, equations, and Excel examples and MBAL;
- The Fetkovich method;
- Fundamentals of the rest of the methods for reservoir behaviour prediction;
- 3. Well operational parameters:
- Determination of well interference and selection of wells suitable for conversion from production to injection well and vice-versa;
- Well pressure data collection; Influence of the reperforating, acid treatments and fracturing on the reservoir performance;
- Using tracers for well communication determination;
- 4. Material balance equation:
- Production material balance of a reservoir;
- Matching the reservoir production material balance and well production history data;
- Examples of material balance;
- Reservoir management economics.
Learning outcomes at the level of the course:
- Distinct the well patterns;
- Decide on a new recovery method;
- Prove the production decline type;
- Analyse the well production data;
- Calculate the reservoir behaviour by using material balance equation.
