The Mittelplate field is the largest German oil reservoir and has been in production for more than 20 years. Due to its maturity there has been a rising interest from its operator to apply Enhanced and Improved Oil Recovery (EOR and IOR) techniques to the field. The general objective of this thesis is the evaluation of EOR and IOR potential, considering technical boundary conditions implied through rock and fluid properties of the reservoir additionally to economical considerations. Corner points for this evaluation are technical screening studies, adapted from well known literature resources as Taber et al. or done through the application of commercially available software. To complement the screenings, different technical studies of key parameters, such as the minimum miscibility pressure, have been undertaken to improve the viability of the evaluation. With the results from the screening processes a commercial software package was used to analyse possible EOR methods analytically, to judge not only the applicability but as well the performance potential of the different techniques. Supplementary emphasis has been put into an economical analysis, based on a sample case, for a possible chemical project, which yielded the most promising technical results. Again commercial software was used to satisfy corporate standards. Based on all economical and technical assessments, suggestions will be given on a continuative project plan including tracer studies, laboratory analysis and numerical simulations for a chemical injection project within certain areas of the Mittelplate oil field.
