From Field to Simulator - An Applied Basin and Petroleum Systems Modeling Workshop

AUDIENCEThe workshop is designed for geoscientists or other oil and gas professionals with petroleum geology background, as an introduction or reminder of basin and petroleum systems modelling.

DESTINATIONThe Lodeve Basin, Southern France

TRIP LEADERProfessor Michel Lopez is professor at the University of Montpellier, France, specialized in sedimentology, basin geology and metallogeny and has more than 30 years of experience in international consultancy and lecturing both in industry and academia. Dr. Martin Neumaier is a senior geologist with Schlumberger, with interests in regional and basin geology, basin and petroleum systems modeling, prospect evaluation and risking, conventional and unconventional resource assessment.

ACTIVITIESAfter an introductory classroom session in Montpellier, we will drive to the Lodeve Basin to visit well exposed outcrops of source, reservoir and seal rocks, complemented by the study of spectacular faults and fractures, unconformities and oil seeps. Back in the classroom, we’ll implement these field observations into 1D and 2D PetroMod models to simulate the evolution of the Lodeve Basin and its petroleum systems in a series of hands-on exercises.

The Lodeve Basin (southern France) is an outstanding example of a half graben basin, with well exposed source, reservoir and seal rocks, and oil seeps proving the presence of an active petroleum system. This blended field to classroom workshop aims to observe and discuss the petroleum systems elements and processes based on the visit of high quality outcrops, prior to the integration of those field observations into the Schlumberger software PetroMod. Hands-on exercises and group discussions build the core of the classroom sessions.

OBJECTIVES■ Observe the basin structure, stratigraphy and petroleum systems elements (source, reservoir,

seal, overburden rocks) and implement those into a model;■ Discuss upscaling of detailed field measurements into model cells (source rock net-to-gross,

total organic carbon, etc.) and effects on modeling results (e.g., hydrocarbon potential);■ Understand the importance of dynamic process thinking in field observations: unconformities

and associated erosion periods and amounts, faults and fractures and their possible causes and timing, oil seeps and their provenance, overall timing of petroleum systems elements and processes;

■ In hands-on 1D and 2D modeling exercises, test different geological scenarios (heat flow, erosions, etc.) to reproduce outcrop observations (oil seeps) and measurements (vitrinite reflectance, Tmax) and discuss modeling results versus field reality;

■ Based on the integration of outcrop observations and basin and petroleum systems modeling, evaluate the exploration potential of the Lodeve Basin and other nearby basins of similar age.

AGENDA

DAY 1INTRODUCTION AND LODEVE BASIN■ General introduction■ Introduction to Basin and Petroleum Systems Modeling■ Basic Theory■ Case Study Lokichar Basin■ Introduction to Lodeve Basin

The workshop starts with an introduction to Basin and Petroleum Systems Modeling (BPSM), including some light theory and a case study demonstrating the application of BPSM in the Lokichar Basin, onshore Kenya, a continental rift basin which will be compared to the Lodeve Basin throughout the workshop.

After a short transfer to the field area in the afternoon, the participants will receive an on-site introduction to the Lodeve Basin.

DAY 2STRUCTURAL AND STRATIGRAPHIC ARCHITECTURE OF THE LODEVE BASIN■ Overview of Lodeve Basin■ Base Permian unconformity■ Lower Permian black shales: source rock stratigraphic logging

exercise■ Mid Permian unconformity■ Red Permian and Permo-Triassic unconformity

On the first day in the field, the different formations of the basin stratigraphy will be visited and discussed with respect to their potential in terms of source, reservoir and seal rocks (petroleum systems elements).

DAY 3DYNAMIC ASPECTS OF THE LODEVE BASIN■ Overview of syn-rift geometry in Red Permian■ Syn-rift faulting and role in hydrocarbon migration and trapping■ Fracture dynamics■ Regional overview

The second field day focuses on dynamic aspects of basin formation, in particular syn-rift faulting and fracturing, and petroleum systems processes such as hydrocarbon migration and trapping are discussed.

DAY 4TRANSITION FROM FIELD TO SIMULATOR AND SCENARIOS■ Recapitulation of field observations■ Upscaling exercise of logged source rock stratigraphy■ 1D petroleum systems modeling■ Calibration to field measurements■ 1D scenarios

Participants will learn about pitfalls related to upscaling of measured source rock properties into the software. Measurements made in the field will be used to calibrate 1D models in hands-on exercises, which allow to test geological scenarios about erosional amount, heat flow etc.

DAY 5SCENARIOS (CONTINUED) AND ANALOGUES■ 2D petroleum systems modeling workflow■ 2D scenarios (source rock properties, migration pathways, etc.)■ Continental rift basin analogues■ Discussion and conclusion

Using 2D models, further geological scenarios are discussed and evaluated for their impact on the exploration prospectivity in the Lodeve Basin and surrounding basins. The modeling results are confronted with known regional oil occurrence as well as analogue continental rift basins in the world.
