FACILITATOR: TBD

DATE:
TBD, September 15-18, 2019

TIME:
8:30am – 4:30pm

LOCATION:
Little America Conference Center, Cheyenne, Wyoming

This course will present several case studies of actual horizontal wells from the Rocky Mountain Region that presented unique challenges in planning and execution. Case studies from the Williston, Powder River, and DJ basins will be presented and discussed. Representatives from the teams that planned and drilled these wells will take participants through each step of the process, and discuss how problems and unforeseen circumstances were recognized and overcome, and how lessons learned from the case study wells were applied to future drilling in the respective areas. Participants will have the opportunity to ask questions about how critical decisions were made along the way, and share similar experiences with wells they were involved with. It is hoped that these opportunities to interact will be mutually beneficial to everyone who is involved in the planning and drilling of horizontal wells in the Rockies.
Who should attend:

Geologists, Drilling/Production Engineers, Service Company Representatives who are or may be involved in planning/drilling horizontal wells in the Rocky Mountain Region.

Sequence Stratigraphy of Resource Plays

Dr. Ali Jaffri
Applied Stratigraphix, LLC

DATE:
TBD, September 15-18, 2019 (2 days)

TIME:
8:30am – 4:30pm

LOCATION:
Little America Conference Center, Cheyenne, Wyoming

This course introduces participants to the sedimentology of unconventional reservoirs and then covers sequence stratigraphic applications.

Due to the homogeneous nature and limited thickness of most unconventional resource plays, seismic has very limited applicability. Therefore this is not a Seismic Stratigraphy course and the bulk of our time will be investigating these reservoirs using well logs (including borehole image logs), core and thin- sections. Each day of the course will be devoted to one play type with case studies from popular oil and gas fields within North America.

The instructor will provide a small collection of well logs and core photos, but we strongly urge participants to bring paper copies of their own data to work on. These data will not be shared with anyone and the instructor will only review the work done by participants.

COURSE OUTLINE

1: INTRODUCTION

1.1. Will it add value to your business?
1.2. Difference between sequence stratigraphy in conventional vs unconventional reservoirs
1.3. Why it matters – geosteering applications

2: TIGHT OIL SANDSTONES

2.1. Are these even true sandstones?
2.2. Concept of the “halo play” – why it works.
2.3. Sequence stratigraphy examples from the Gallup-Mancos of the San Juan Basin and the Frontier- Turner-Parkman of the Powder River Basin.

3: SHALES

3.1 Classification of fine-grained rocks
3.2 Myths, half-truths and truths about shale: deposited in low-energy, shales are anoxic, shales are pelagic, shales are deposited in deepwater, shale are homogeneous, most shales have carbonate components, shales get deposited during transgression, shale fractures depend on grain richness, the higher the natural fracture density the better, all hydraulic fracs will cutacross bedding boundaries

4: PLATFORM CARBONATE MUDROCKS

4.1 The diversity of platform interior mudrocks and controls on microporosity
4.2 Sequence Stratigraphy examples from the Bakken and Three Forks in the Williston Basin

5: BASINAL CARBONATE MUDROCKS

5.1 Platform margin classification
5.2 Mass Transport and sediment Gravity Flows

LOCATION:
Little America Conference Center, Cheyenne, Wyoming

This two-day short course focuses on the challenges and issues that arise when hydraulic fracturing operations are conducted in horizontal wells, as compared to vertical systems. The mechanics of completion and diversion techniques and tools, such as plug-n-perf and sliding sleeves, will be discussed, along with the pros and cons of these various horizontal well completion systems. In-situ stress profiles and their effects on transverse and longitudinal fracture growth, both near wellbore and far-field, will be addressed. Stress shadowing and the resulting impacts on cluster and stage spacing will be reviewed. Proppant and fluid selection, proppant transport, and the conductivity requirements will be discussed. The application of diagnostics, such as DFIT’s and geometric measurements (tracers, microseismic, fiberoptics, etc.) will be reviewed, along with how the results can be integrated for enhancing future treatments. Other topics include: perforating, fracture clean-up, flowback, brittleness, enhanced permeability volumes, treatment optimization, and post-treatment analysis. All disciplines are welcome to attend the course; however, a basic understanding of hydraulic fracturing should already be in place prior to enrollment.

LOCATION:
Little America Conference Center, Cheyenne, Wyoming

The late Mississippian to early Pennsylvanian Heath and Tyler Formations in central Montana and the Williston Basin, North Dakota contain well documented conventional reservoirs and have produced more than 95 MMBO in central Montana and 87 MMBO in North Dakota.  Both producing areas have associated organic-rich source rocks that have been the subject of oil resource play assessments starting in the late 2000s.  Multiple pilot holes with cores and modern logs have been drilled in both Montana and North Dakota, yielding new data that are helping geologists better understand the lithofacies, depositional environments, and ages of these strata.  Workers in the past have been challenged to correlate these units from the type area outcrops in central Montana, to the central Montana subsurface, and into the Williston Basin in North Dakota, and these new data are facilitating a new discussion on how these units are areas relate to one another.

COURSE OUTLINE

Key elements of the Tyler and Heath that will be observed in this workshop include:

  • Cores from central Montana that illustrate typical lithologies of the Upper Tyler, the Bear Gulch Limestone, the Lower Tyler, and the Heath;
  • Cores from North Dakota that illustrate lithologies found in the Central Basin area (high gamma ray shales within the siliciclastic dominated lower Tyler) and in the southwestern Tyler producing area (mixed carbonate-siliciclastic upper Tyler);
  • Lithologic distinctions between variously defined units in the Tyler of central Montana, including upper Tyler, Bear Gulch Limestone, lower Tyler, Cameron Creek “Member”, and Stonehouse Canyon “Member”; and a discussion of what terminology is most useful;
  • Cyclicity in the late Mississippian and early Pennsylvanian strata related to glacio-eustatic sea level fluctuations;
  • A discussion of oil types present in central Montana and the Williston Basin associated with Heath-Tyler reservoirs and source rocks.
Who should attend:

This course will be of interest to anyone working on the oil resource potential or conventional oil potential of the Tyler and/or Heath Formations in Montana and North Dakota, those working on self-sourcing tight oil carbonate systems, workers assessing resource plays that involve thinly interbedded lithologies, geoscientists interested in mid-Carboniferous cyclical sedimentation, , and those interested in better understanding the stratigraphic and geological history of Montana and North Dakota.
