An Overview of Exploration Risk Analysis for Senior Management

Risk Analysis for Managers

This special offering seminar synthesizes the key concepts and applications of risk analysis (RA) and personnel performance for leaders in your organization. The purpose - illustrate exploration as a predictable and profitable long-term business within the context of Portfolio Management. What makes this seminar unique is it goes beyond RA and helps leaders address the critical people element, providing a systematic approach to effectively enhance their overall performance.

Predictability of exploration portfolios is the desired outcome of all that we do and teach. The inherent power of our systematic RA methodology will help you design and enhance the predictability of your portfolios to best meet your corporate goals. Additionally, we address key management issues, common misconceptions, and pitfalls. You will be exposed to the highlights of the critical management tasks necessary to cause progressive improvement in exploration performance, including dealing clearly and objectively with the truth, not only in the performance of your portfolio but also the performance of your people.

In this special offering, we will incorporate the Managerial Moment of Truth (MMOT), a powerful process that can dramatically improve performance, increase productivity, and change your culture at minimal cost. This dynamic technique helps people face up to reality and confront the truth in order to correct mistakes, learn from past performance, and adjust processes to build a more successful organization. MMOT will show you how to use four steps to establish a culture of truth, so that it is not softened, avoided, or worked around.

Because the course integrates fundamental topics such as Uncertainty, EUR Estimates, Chance of Success Predictions, Portfolio Management, Performance Tracking, and Personnel Performance Management, we strongly encourage the participation of decision-makers with diverse backgrounds, such as Geoscience, Engineering, Finance, and Human Resources.

Course Outline

1. Risk Analysis: The What and Why of an appropriate implementation

2. Statistics: The Language of Uncertainty

3. Coping with Uncertainty and Its Consequences

4. Prospect EUR and Chance: The Appropriate Characterization

5. Managing Exploration by Managing the Portfolio

Structural Restoration and Petroleum Systems Modeling of the Wyoming-Utah-Thrust Belt

Hans Axel Kemna, Monika Majewska-Bell, Keith Mahon and Kristijan Kornpihl

An approximately 160 km long 2D section of the Wyoming-Utah thrust belt and the Wind River Basin (U.S.A.) including the La Barge and Tip Top gas fields has been modeled using advanced technologies of structural restoration and petroleum systems modeling. The model is based on publicly available data.

Due to the highly complex tectonic history of the area, which is characterized by extensive thin-skinned thrusting as well as basement-involved flexural movements, a detailed structural restoration was carried out using the software package 2DMove. The restoration takes lateral sediment transport, i.e., erosion and re-sedimentation, and flexural isostasy effects into account.

A petroleum systems model was created based on paleo-geometries derived from the structural restoration. Modeling of the temperature/pressure history as well maturation and petroleum migration was carried out using the TecLink application of the PetroMod software package.

The resulting model provides detailed insight into the history of the petroleum systems present in the area, with a special focus on the La Barge and Tip Top gas fields near the eastern margin of the Wyoming-Utah thrust belt. Several petroleum systems and a source of CO2 occur stacked onto each other in this area. Detailed migration simulations with source rock tracking revealed that the occurrence of gas and condensate can only be explained with the presence of very effective sealing lithologies.

The combination of structural restoration and petroleum systems modeling is a very powerful tool for the analysis of petroleum systems in tectonically complex environments. An approved workflow has been established for this purpose.

Natural Fractures in Shales: Origins, Characteristics and Relevance for Hydraulic Fracture Treatments

Julia F. Gale¹ and Jon Holder²
¹Bureau of Economic Geology, University of Texas at Austin, Austin, TX
²Petroleum and Geosystems Engineering, University of Texas at Austin, Austin, TX

Most shales contain natural fractures. We review common fracture types and their characteristics based on core and outcrop studies from several different shales, including Devonian Woodford shales from the Permian basin and the Mississippian Barnett Shale of the Fort Worth basin.

We measured the subcritical crack index of different shale facies. Geomechanical modeling using the index as an input parameter allows prediction of fracture clustering. To do this rigorously, however, requires an understanding of the diagenetic history as it relates to evolving mechanical rock properties, and the timing of fracturing. Thus it is necessary to integrate fracture work with other fundamental geologic knowledge. For example, there can be many different causes of fracturing over the lifetime of a shale. Some fracture sets in Woodford Shale cores are seen to have been deformed by compaction, whereas some others are later. The mechanical properties of the pre-compaction rock at the time of early fracturing are likely to be very different from those prevailing at a later, post-compaction stage. The resulting fracture patterns and sealing characteristics for the different fracture sets are likely to be different also.

The relevance of natural fractures in these shale gas plays is that they are weak planes that reactivate during hydraulic fracture treatments. We have observed fracture planes only half as strong as the host rock during tensile testing. The first step towards understanding whether hydraulic fractures will be affected in a given zone is to predict the natural fracture patterns and measure the in situ stress.

Porosity Prediction in Deep Eolian Reservoirs from Early Diagenetic Process Models
A Modern Desert Study in Saudi Arabia, New Mexico, and Namibia

Joanna Ajdukiewicz -- Geologist
ExxonMobil Exploration Company, Houston, TX, USA

Favorable reservoir quality in deeply buried sandstones is preserved by early formed grain coats that inhibit growth of high-temperature quartz cement during later burial. Deep eolian reservoirs with grain-coat-preserved porosity include the Norphlet, USA; Rotliegendes, Europe, Nugget/Navaho, USA, and Unayzah, Middle East. Porosity- preserving coats in these reservoirs are mainly composed of infiltrated and diagenetic clays. Coat effectiveness increases with greater coat continuity. Reliable deep porosity prediction requires accurate models for the presence, continuity, and distribution of early grain coats.

A collaborative Saudi Aramco-ExxonMobil study was undertaken to document the distribution and genesis of grain coats in modern eolian settings. Studies of coat formation in eolian settings with different climatic conditions were undertaken in Saudi Arabia, New Mexico, and Namibia. Coat characteristics were evaluated using petrographic analyses and laboratory experiments. Results indicate that coat continuity and effectiveness vary by EOD as well as climate. Infiltrated clay coats form either by percolation of muddy water into wadi and nearby eolian sands after periodic flooding, or illuviation of airborne dust during early soil formation. Continuous diagenetic coats form early in sediments buried to or below the water table. Coated grains blown from these environments into active dunes lose their coats by abrasion during eolian transport, most likely in a multicyclic process of coat formation and destruction. In arid climates, dunes remain active, and grain coats are abraded more quickly than they can form. Wetter climates favor sediment stabilization and coat formation. Consequently, more continuous coats and highest porosity preservation occur in dune sands prone to periodic wetter climate conditions, overbank and sheetflooding, and/or rising water tables.

Hot U.S. Plays: Mostly Shale

Part I (Part II in October)

Stephen Trammel

Key U.S. onshore unconventional oil and gas plays and the Gulf of Mexico, especially the ultra deepwater, Lower Tertiary Trend, continue to attract high bids for acreage. Industry is evaluating potential shale gas reservoirs across the country, geographically and throughout the stratigraphic column—leaving no stone unturned, so to speak. With some notable exceptions for oil plays (Deepwater Gulf of Mexico the Bakken play in particular), the U.S. industry is focusing on gas. Here is the current situation: higher natural gas prices stimulated increased drilling activity, but gas production only has reached an undulating plateau. A shift to lower volume unconventional gas implies further drilling increases to sustain production.

Complications include: rising capital costs; uncertainties about the regulatory climate; questions whether high gas prices will hold; manpower/rig shortages and periodic transportation bottlenecks; energy security needs and growing anti-hydrocarbon sentiments and policies in support of climate change targets could restrict future oil and gas developments; access to potentially large resources currently is restricted due to these environmental and lifestyle issues. Concerns include: what are the implications of these trends on North America gas supplies?

Unconventional gas resources will continue to increase in importance in the U.S. energy mix. Most areas with strong drilling activity are targeting unconventional gas—about 75% of the current gas-related rig count. Of the top 25 U.S. gas fields ranked by production, 20 are classified as unconventional. A strong upside exists through relentless pursuit of new technologies and process improvements. However, a collaborative process among all stakeholders is critical: manage developments with local community concerns; balance climate change policies with gas supply needs, and reach a compromise on access restrictions to high resource potential areas. If the challenges are met, we may be reaching a tipping point in U.S. gas production where unconventional gas and gas from new Gulf of Mexico hubs like Independence, can offset the decline in conventional gas production. This presentation will focus on the activity trends in the lower 48 that industry appears most committed to developing, including both onshore plays and the Lower Tertiary Trend in the ultra deepwater Gulf of Mexico.

Lacustrine Kitchens
Keys to Exploration Success in the Pre-Salt Play, Santos Basin, and Potential along the Eastern Brazil Margin

William Dickson -- Founder
Dickson International Geosciences, Houston, TX, USA

Craig Shiefelbein -- President
Geochemical Solutions International, Shenandoah, TX, USA

In a 2005 poster at AAPG Calgary, the authors integrated geochemistry with detailed maps and revealed trap potential on the unexplored south flank of the Santos basin. Pre-salt basins and individual paleo-lakes were imaged, migration pathways were defined, the limits of different petroleum systems were mapped and a pre-salt play in Brazil's Santos Basin was predicted.

With a subsequent series of significant discoveries, it was time to test predictions against facts. Aided by more and better data, the earlier correlations were first re-examined within the Santos Basin and then along the eastern Brazil margin where similar data supported analogous conclusions.

Key findings relate to widespread evidence for lacustrine-sourced oils, frequently partially masked by multiple phases of migration from the same source type or from younger marine source intervals.

Many structural compartments were mapped from potential fields data, then correlated to geochemical indicators from oil samples and piston cores. These compartments showed subtle variations among a small number of basic oil families with distinct spatial extents. Family trees, constructed by sorting oil indicators in multivariate space, demonstrated genealogical extents. Potential fields, piston cores, remote sensing, literature and other material illustrated spatial extents. Links are shown between these lacustrine kitchens and recent discoveries in the Santos Basin.

Gas in Place Identification from Mudlog Gas
Barnett Shale - Fort Worth Basin, Texas

Jeffrey E. Nunneley
Marathon Oil Company, Houston, TX

Total gas in place (GIP) within a shale is commonly identified by directly measuring the volume of gas given off from sections of full core sealed in canisters at the well site. It is usually measured in standard cubic feet per ton (SCF/ton) and includes free gas in pore spaces, adsorbed gas, plus gas dissolved in liquids in the pores. Gas that is liberated from the rock during the drilling process is frequently measured on a mudlog. The low permeability of a gas shale allows little migration of formation fluids into the well bore during drilling. The gas that is measured on a mudlog represents the total gas present in the volume of rock ground up and removed from the well bore. The mudlog gas can be normalized for penetration rate and mud flow volume to yield total gas from the mud system in parts per million. The volume of rock that is ground up while drilling and the density of the rock can be measured from wireline logging tools after drilling is completed. The combination of hole volume and rock density allow for calculation of the ground up rock mass responsible for the measured gas in the mud system.

GIP values from a canistered, Barnett Shale core have been compared to the GIP values calculated from a normalized mudlog. The two values have a favorable, relative relationship. The mudlog calculated data is more variable in magnitude than that of the canistered core data. A “calibration factor” must be applied to the mudlog gas calculation in order to match the magnitude of the conventional core data. This “calibration factor” is mainly related to the sampling process of the mudlog detector which only samples a portion of the gas present in the total volume of the mud system.
