N186 Complex Carbonate Reservoirs: Influence of Facies and Tectonic Processes on Porosity Development (Southern Italy)
N186 Complex Carbonate Reservoirs: Influence of Facies and Tectonic Processes on Porosity Development (Southern Italy)
The course follows the trajectory of a virtual well drilled in the prospective Monte Alpi (and Tempo Rosso) trend. The effects of a contractional regime on a wide range of carbonate rocks, from basinal to platform margin and interior facies, are observed. Principal among these effects is fracturing, and the resultant implications for reservoir performance are examined. The development of karstic macroporosity is also reviewed.
Six field days covering the Apennine Mountains of Southern Italy from the Tyrrenian coast to the Adriatic coast, starting in Naples and finishing in Rome. The course is primarily field-based with maximum time spent in front of the outcrops. There is a short classroom session on the first night to introduce the regional geology. Examples of public domain data from the local producing areas are included wherever possible to enhance the generic principles outlined during the course.
Participants will learn to:
Carbonate reservoirs are liable to display a large variability in their characteristics, affecting both performance and economic viability. Prominent among these are primary facies distribution and properties, the sequence stratigraphic framework, diagenesis and fracturing.
Numerous subsurface disciplines contribute to carbonate reservoir characterisation, such integration being crucial to an understanding and prediction of dynamic reservoir performance, and ultimately leads to more closely focused exploration, reservoir development and depletion strategies.
To achieve such a comprehensive reservoir picture, geoscientists must make use of outcrop analogues, evidence from which can be integrated with subsurface datasets from the specific reservoir under study. For the models to have predictive capability, the regional geological evolution however needs also to be integrated to place the reservoir and the processes through which it has been subjected in context. This field seminar aims to provide such elements.
The field area includes a wide range of sedimentary facies, stratigraphic architecture and structural environments, all within a highly compressive setting, sampling two Mesozoic to Cenozoic carbonate platforms, the Apulian and Apenninic, which formed, grew and then collided as elements of the interaction between the African and Eurasian plates. The two platforms and the previously intervening Lagonegro Basin are now stacked in complex thrust sheets in the southern Apennines.
The Apulian Platform is reservoir in the giant Eni-Shell oilfields of the Val d’Agri and also in the undeveloped Tempa Rossa field. Fractures and karst play a major role in the production performance of these fields.
In each segment of the class there is emphasis on the linkage between depositional facies, structural development and fracture formation.
Course Itinerary
Day 0
Days 1 and 2
Days 2 and 3
Days 4-6 at Monte Maiella
A sampled pop-up of the Apulian Platform’s northern margin that exposes the platform-slope-basin transition from Turonian to the Eocene. 1000 m of original topographic break can be inferred.
End of Day 6
Petroleum geologists, reservoir engineers and geophysicists working on carbonate sequences, especially where there is a close relationship between facies, fracturing, structure and potential reservoir performance. Ideally, the components of a subsurface team would greatly benefit from participating together.
Participants with familiarity with carbonates will benefit most from this course. There are no formal prerequisites but Nautilus Training Alliance classes N020 (Carbonate Depositional Systems) and N059 (Applied Carbonate Geology) provide suitable primers. N143 (Advanced Concepts in Carbonate Exploration and Reservoir Characterization) can be considered as a linking course, outlining a number of the new and developing ideas in carbonate reservoir geology.
The physical demands for this class are MODERATE according to the Nautilus Training Alliance field course grading system. The majority of the stops are close to the coach or involve short walks of a kilometre or two on good trails. Many outcrops are in quarries and these may be uneven underfoot with occasional scrambling up or down quarry benches. Temperatures are expected to be comfortable but it can be hot, especially in the quarries. The final day involves greater physical demand with a 6 km (4 miles) mountain hike up a steep trail at an elevation of up to 1800 m (6000 ft). Participants need to be equipped for the mountain day with waterproofs and warm clothing, as well as prepared for hot or variable weather on other parts of the trip.

Background
Davide is an explorer at TOTAL. He has 23 years of experience in the oil and gas exploration business. He worked on projects spanning exploration to reservoir development for BP, Marathon, Apache and TOTAL. Davide’s experience includes exploring, developing and managing carbonate and clastic reservoirs in the North Sea; Atlantic Margin; Mediterranean, West Africa and South East Asia.
His main expertise is in mapping the structure and stratigraphy of sedimentary basins using a range of datasets and skills including quantitative seismic interpretation and outcrop analysis. He has mapped several sedimentary basins both in the subsurface and in outcrop with various structural configurations and with carbonate and clastic fills. He has experience in working at various scales from the pore size to the basin scale.
His main professional interest is the integration of data and disciplines aimed at finding and developing hydrocarbons safely for profit.
Davide is author of several technical papers.

Background
Raffaele speaks fluent English, French and Italian.
He’s presently partner and Technical Director of G.E.Plan Consulting s.r.l.in Ferrara, Italy where he deals with project management, reservoir characterization projects and development of new opportunities. He previously held technical positions with TOTAL S.A. (France), FINA E&P (Italy) and began his career with Arco British in the UK.
He has 15 years experience in E&P industry and he has worked as an asset geologist, an exploration geologist over deep offshore plays and as a reservoir geologist/petrophysicist over fractured carbonate and clastic turbidite reservoirs. During his career he was involved in multidisciplinary studies from the early exploration basin evaluation to reservoir characterization, seismic and drilling projecting, early production, reservoir modeling and late re-evaluation of old HC fields.
Since joining G.E.Plan Consulting in 2004 he has been involved in building and managing new attractive exploration portfolios for small and medium-size E&P companies in Italy and Europe by evaluating the potentials of onshore and offshore sedimentary basins together with previous exploration and production activities and by coordinating the new exploration activities.
During his career he has worked on projects in different countries of Europe, Middle East, Russia and a former Soviet Countries and North and Central Africa. He’s also involved in research projects focusing on the characterization of fractured carbonates and dolomitized reservoirs using different techniques and approaches.
