Crude production in the US topped an average of 13.3 million B/D in December according to the latest estimate from the US Energy Information Administration (EIA). The new figure, both a global and US record, is about 300,000 B/D above the nation's pre-COVID 19 pandemic November 2019 peak. While the number of new wells added each year has served as a key driver of production growth, the EIA suggested that is no longer the case. Instead, it credited advances in drilling and hydraulic fracturing technology which have not only increased well productivity but have also led to a stabilization in output from existing wells since 2021. Although the report did not detail specific technologies contributing to the growth, a major trend emerging in the US shale sector is the shift toward 3-mile lateral wells.

All are playful nicknames for the oil and gas icon known as a pumpjack. To the uninformed, the pumpjack is a thing-a-ma-jig that has something to do with oil, probably "fracking" because that's what drilling rigs do, right? But as an industry-educated and well-informed reader of JPT, you know this is inaccurate. By whatever name you call it, you know that the pumpjack is the visible manifestation of an invisible physics equation, a mechanism buried deep underground that lifts reservoir fluids to the surface. You also know it is one type of artificial lift available in a stable of systems with equally curious and technical names like progressive cavity, plunger, jet, gas lift, and electrical submersible pump (ESP).

ABSTRACT Organic matter (OM) maturity is closely related to organic pores in shales. Quantitative characterization of organic and inorganic pores in shale is crucial for rock-physics modeling and reservoir porosity and permeability evaluation. Focused ion beam-scanning electron microscopy (FIB-SEM) can capture high-precision three-dimensional (3D) images and directly describe the types, shapes, and spatial distribution of pores in shale gas reservoirs. However, due to the high scanning cost, wide 3D view field, and complex microstructure of FIB-SEM, more efficient segmentation for the FIB-SEM images is required. For this purpose, a multiphase segmentation workflow in conjunction with a U-net is developed to segment pores from the matrix and distinguish organic pores from inorganic pores simultaneously in the entire 3D image stack. The workflow is repeated for FIB-SEM data sets of 17 organic-rich shales with various characteristics. The analysis focuses on improving the efficiency and relevance of the workflow, that is, quantifying the minimum number of training slices while ensuring accuracy and further combining the fractal dimension (FD) and lacunarity to study a simple and objective method of selection. Meanwhile, the computational efficiency, accuracy, and robustness to noise of the 2D U-net model are discussed. The intersection over the union of automatic segmentation can amount to 80%โ95% in all data sets with manual labels as ground truth. In addition, calculated by the FIB-SEM multiphase segmentation, the organic porosity is used to quantitatively evaluate the OM decomposition level. Deep-learning-based segmentation shows great potential for characterizing shale pore structures and quantifying OM maturity.

ABSTRACT Understanding the elastic and attenuation signatures of shales is of considerable interest for unconventional reservoir characterization and sealing capacity evaluation for CO2 sequestration and nuclear waste disposal. We have conducted laboratory measurements on seven shale samples at seismic frequencies (2โ100ย Hz) to study the effects of clay-bound water (CBW) on their wave dispersion and attenuation signatures. With nuclear magnetic resonance and a helium porosimeter, the volume of CBW in the shale samples is quantified. The forced-oscillation measurement reveals that Youngโs modulus exhibits a continuous dispersion trend from 2 to 100ย Hz. The extensional attenuation () shows a weak frequency and pressure dependence on effective pressure ranging from 5 to 35ย MPa. The magnitude of extensional attenuation shows a positive correlation with CBW, with an value of 0.89. It is found that 4% of CBW in the rock frame causes approximately a 5% modulus increase from 2 to 100ย Hz. We adopt a constant model for assigning frequency-dependent bulk and shear moduli to the CBW in the rock-physics modeling, which can fit the experimental data of modulus dispersion and attenuation well, indicating that the bulk and shear moduli of CBW in shales might behave viscoelastically.

Houston-based Chord Energy has announced plans to acquire Canadian producer Enerplus Corp. in a deal with an implied valued at 3.8 billion. The transaction, which involves a combination of stock and cash, will create a company with an enterprise value of 11 billion. The company's footprint will expand to 1.3 million acres, 98% of which is in North Dakota's Williston Basin which is home to the prolific Bakken Shale. The transaction aligns with the ongoing consolidation trend in the North American shale sector that has been marked in recent months by major acquisitions from large oil and gas companies including ExxonMobil, Chevron, Chesapeake Energy, and Diamondback Energy. Chord said its daily output will increase as a result of the deal to a basin-leading average of 287,000 BOE/D, about 56% of which is crude oil.

Diamondback Energy has announced its acquisition of Permian Basin rival Endeavor Energy Resources in a cash-and-stock deal valued at approximately 26 billion. The consolidation will create a firm worth almost 60 billion. It also underscores the recent shake up of the US shale sector, following a year in which mergers and acquisitions topped 192 billion, with an additional 40 billion occurring in this quarter alone, according to figures from Enverus Intelligence Research (EIR). The trend underscores the drive of large operators to add significant volumes of flowing barrels along with untapped drilling locations to secure long-term viability. Prior to today, Diamondback itself has made more than 4 billion in other cash-and-stock deals to enhance its drilling inventory and cash flow from mineral rights since 2022.

Abstract Continuing from the previous publication (Navaiz et al. 2023) detailing the hydraulic fracturing energy system and energy transfer as fluid and proppant are pumped from the surface into formation. this paper focuses on the validating the importance of effective energy delivered to formation and its correlation to total productivity. Combining extensive in-house pumping data and well-production data available from the public domain, a two-dimensional approach cross-plotting total effective energy injected per unit area against production output shows a highly correlative positive relationship (R2>0.75) across several basins in North America. This strong relationship not only reinforces the value of this energy analysis concept in hydraulic fracturing established by the authors previously. It also validates the conservation of energy principle highlighting the usefulness of relating effective energy injected into formation to a direct increase in reservoir energy potential and therefore a greater potential for total productivity. With the unconventional oil and gas industry highly focused on capital efficiency, the effective energy metric enables near-instantaneous optimization of development costs rather than iterating on 6-month or 1-year production performance. Time and capital can then be invested in technologies and processes that maximize effective energy and resultant productivity or minimize energy losses in the system.

Shale gas producer BKV Corp. has made the leap into the US carbon capture and storage (CCS) sector, becoming the latest upstream firm to challenge the idea that only industry giants can make significant moves in this emerging arena. Founded in 2015 as a privately held subsidiary of Thailand's coal and energy conglomerate Banpu, BKV and its fewer than 400 employees have quickly built the company into the 17th largest gas producer in the US. In addition to its upstream operations in the Barnett and Marcellus shales, BKV's business model borrows from its Thai energy roots and includes ownership of two natural gas power plants in Texas. But the firm is better known within upstream technical circles for its leadership in refracturing horizontal wells in the Barnett where it is the largest operator both in terms of acreage and flowing wells. No stranger to diversification, BKV is now shifting its focus to CCS--a market anticipated to balloon almost fivefold from 3 billion to over 14 billion by the end of the decade.
