Overview

As Tier 1 acreage in the Bone Spring and Wolfcamp formations becomes increasingly constrained, operators are turning to emerging zones for the next wave of development. TGS data reveals that while traditional landing zones continue to deliver strong oil production, they are producing higher water volumes and rising water-oil ratios as inventories mature.

Haynesville Basin Development Analysis: Legacy vs. Western Regions

matt.mayer@tgs.com (Matt Mayer) — Thu, 21 Aug 2025 00:18:14 GMT

Overview

This comprehensive analysis examines the contrasting development patterns, production performance, and infrastructure challenges between the Legacy Haynesville and emerging Western Haynesville regions. While Legacy Haynesville currently dominates production volumes with established infrastructure, the Western region (comprising Robertson, Limestone, Freestone, and Leon Counties in Texas) demonstrates significant growth potential and competitive well performance. However, this potential is contingent upon critical midstream infrastructure development to overcome higher costs and execution risks associated with the high-pressure, deep reservoirs characteristic of the Western region.

Introduction

The oil and gas industry is undergoing a significant transformation, driven by a surge in mergers and acquisitions that are reshaping the competitive landscape. These transactions reflect the sector’s adaptability to shifting market conditions and have the potential to influence the scale of U.S. hydrocarbon production, particularly from unconventional sources. As companies navigate this evolving environment, assessing the economic viability of assets remains critical, with factors such as commodity prices, operating costs, and regulatory policies playing a key role in shaping production trends.

Unlocking New Frontier Basins in Brazil’s Oil and Gas Exploration

Brazil is a powerhouse in oil and gas production, ranking as the largest producer in Latin America and home to some of the world’s largest recoverable ultra-deep oil reserves. With a coastline of approximately 7,400 kilometers, among the longest globally, Brazil holds significant untapped potential for hydrocarbon exploration.

New Life in The Barnett Shale

As the search for new drilling opportunities in the Permian Basin continues, more operators are investigating lesser-developed formations and the basin’s outer edges. While the Spraberry and Wolfcamp intervals in the Midland Basin remain primary targets, operators are increasingly exploring deeper zones and fringe areas. Recent filings with the Texas Railroad Commission (RRC) indicate a rise in drilling and permitting activity in less-targeted formations like the Barnett Shale and Woodford formations.

Laura Sanchez — Mon, 05 Feb 2024 19:31:03 GMT

In the ever-evolving landscape of the oil and gas industry, the echoes of transformative change resound through the recent surge in merger and acquisition activity. Since October 2023, the sector has witnessed a seismic shift with notable transactions, including the groundbreaking ExxonMobil Pioneer deal, the strategic maneuvers of Chevron Hess, and the dynamic synergy of OXY CrownRock. These mega-mergers underscore the industry's resilience in adapting to market conditions and will influence the scalability of U.S. hydrocarbon production, particularly from unconventional sources.

Unlocking Shale Potential: A Case Study on Seismic-Guided Shale Development

matt.mayer@tgs.com (Matt Mayer) — Wed, 18 Oct 2023 18:32:57 GMT

This year marks the 100-year anniversary of commercial field development in the Permian Basin with the successful discovery of Santa Rita No. 1 in May 1923. Then, in the early 2000’s a new technological discovery, unconventional drilling and completions, or fracking, was operationalized in the Permian and allowed for extraction from previously unavailable reservoirs. While new unconventional wells could return orders of magnitude higher hydrocarbon volumes, they also proved much more costly to drill and complete, where wells with over 10,000-foot laterals could cost upwards of $10 million in CAPEX. Although these new unconventional reservoir targets were typically well-explored from a regional perspective, unconventional well performance still varies widely based on localized changes in individual landing zone thickness, stress orientation, and reservoir geomechanical properties.

Predicting Subsurface Attributes with Machine Learning in Unconventional Basins

keyla.gonzalez@tgs.com (Keyla Gonzalez) — Thu, 09 Mar 2023 23:06:49 GMT

Wireline logs are a fundamental aspect of subsurface property characterization. However, economic constraints often limit data acquisition from specific logs or depth intervals, resulting in incomplete information from the well’s surface to its base in many areas. An alternative that addresses the lack of data is to create synthetic curves. With the advent of data science and the availability of digitized well data, machine learning (ML) algorithms can be used to predict missing logs or log intervals. TGS’ Analytics Ready LAS (ARLAS) leverages both the vast amount of well log data in the TGS library as well as data management infrastructure. TGS algorithms provide curve predictions for five standard curves, including the confidence intervals of each log which can be used for automated interpretation such as facies classification or basin stratigraphy.

Reveal the Best Insights for Carbon Capture and Storage

Climate modeling by the International Energy Agency recommends Carbon Capture and Storage (CCS) as the crucial component to stabilizing global climate. The US Department of Energy recently predicted ten-fold growth of the CCS industry by 2030 suggesting sequestration of 350-1000 GT by the middle of this century. CCS in the United States has been further incentivized by climate-related provisions in the Inflation Reduction act. With all of this activity surrounding carbon capture and storage, it’s a good time to explore how and where CCS can be implemented efficiently.
