Using Shale Capacity to Predict Well Performance Variability: Part 2

As discussed in part 1 of this article, when it comes to the attributes used in equation 1 for seismically determining shale capacity, it is difficult to make a manual choice for the cut off values. To alleviate such a problem, application of machine learning techniques could be useful and thus worth exploring.

It's All About the Future with the Santos Basin

It’s natural to think of super basins as highly developed, mature play areas. When a basin has already produced more than 5 billion barrels of oil equivalent, there’s an established history of exploration and production. The Santos Basin, especially the basin’s pre-salt play offshore Brazil, is one of the more notable exceptions to that idea. This super basin area is almost all about the future. “There is so much running room, so much remaining potential. We’re going to see new reservoirs developed, new plays developed,” said James Deckelman, vice president of investment and program assurance for ION Geophysical in Houston.

AAPG Launches New Salt Basins TIG

A new AAPG technical interest group is attracting international attention, and the founders hope to continue expanding the group’s influence. The Salt Basins TIG began in May 2020 as a way for geoscientists in industry and academia working on or interested in salt basins to connect, collaborate and share ideas, according to one of the co-founders, Rachelle Kernen of the AAPG Women’s Network.

Paleogeography in Exploration

There is something about colored pencils that we, as geologists, find impossible to resist. From geological maps to field sketches to interpreting seismic on those never-ending rolls of paper taped to the longest corridor wall we can find – what more could any geologist want? Our need for powerful software, paper and colored pencils reflects a fundamental problem in geology and especially exploration: how to manage, analyze and visualize the diversity and wealth of information required to solve exploration problems? Early geologists were faced with the same challenge 200 years ago. It was one of the first petroleum geologists, Thomas Sterry Hunt, who saw the value of paleogeography in exploration, and who, in 1873, first coined the term “paleogeography.”

Record-Breaking Gas Discoveries in the Ortoire Syncline

Touchstone Exploration is the operator of the 184-square kilometer Ortoire Block onshore south eastern Trinidad. The block spans from the villages of Tableland in the west to Pierreville Mayaro in the east and to the very remote areas within the Guayaguayare forest to the south. Structurally, the block covers the greater part of the open east facing Ortoire Syncline which entails Late Miocene Lower Cruse to Pleistocene Mayaro Formation deltaic fill. These passive fordeep infill deposits sit conformably onto a southeastern-verging Early to Middle Miocene fold belt. As such throughout the breadth of the Ortoire Block there are numerous tear fault dissected west-southwest to east-northeast trending anticlines.

Geomechanical Modeling Facilitates Better Production, Safer Drilling

Considering that success or failure of unconventional exploration is largely dependent on drilling horizontal wells in the right area and fracturing efficiently, and considering also that geomechanical modeling facilitates these processes, it is easy to see that when industry professionals have a better perspective of the subsurface mechanics, the better chance they have for increased production. That is the point of geomechanical modeling: safer drilling and increased production.

The Importance of Fracture Toughness

Shale resource plays are associated with low permeability, so hydraulic fracturing is required for their stimulation and production. In order to enhance the flow of fluids with hydraulic fracturing, it is vital to understand the stress field distribution. The efficiency and effectiveness of a hydraulic fracture stimulation are predicated on adequate horizontal well placement in the subsurface. For that purpose, the horizontal wells are usually drilled in the direction of minimal horizontal stress so that hydraulic fracturing takes place in the direction of maximal stress that ensures better reservoir contact and production, which also depends on how a complex fracture network is created by induced fractures.

Underexplored Rub' al Khali Basin Could Hold Major Unconventional Potential

It is one of the most remote places on the planet and home to the largest sand desert in the world. Virtually uninhabited and underexplored, the Rub’ al Khali basin, known as “the Empty Quarter” in Arabic, covers more than a fourth of the southeastern part of the Saudi Arabian peninsula. While the area has been explored in the past, perhaps most notably by Max Steineke, the American geologist known for making the first oil discovery in Saudi Arabia in 1938, and then publicly again in the early 2000s by international oil companies, the basin appears to be of increasing interest once more.

When Salt Disappears: Why Should We Care About Welds?

Salt welds form due to salt thinning by mechanical (e.g., salt-flow) and/or chemical (e.g., salt-dissolution) processes. This webinar explores how we use 3-D seismic reflection, borehole, and biostratigraphic data to constrain the thickness and composition of salt welds, and to test the predictions of analytical models for salt welding.

Salt versus Shales in Continental Margins and Orogens

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

Probing What Makes the Crust Strong (or Weak): Insight from Boreholes, Earthquakes, Active Fault Systems, and Toy Models

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them. Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing. Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

DL Abstract By Kurt W. Rudolph

Tectonic Controls on Source Rock Deposition

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.
