An Overview of Carbon Capture and Storage and its Potential Role in the Energy Transition
Authors Joseph M. English and Kara L. EnglishAbstractCarbon capture and storage (CCS) is one of a number of mitigation options and a key component of some proposed negative emissions technologies that can be considered to stabilize atmospheric greenhouse gas concentrations in order to meet the targets set out in the Paris Agreement. CCS involves the capture of CO2 emissions produced from industrial and power generation sources, followed by transport to underground geological storage and long-term isolation from the atmospheric system. Here, we provide a brief introductory review of the steps involved with CCS developments, different options for geological storage, the potential role of CCS in the energy transition, and a discussion of some of the key associated risks and uncertainties. In short, CCS can provide an important avenue for mitigating the increase of greenhouse gases in the atmosphere, particularly during the energy transition.

The Importance of Accurate Timing on Land Seismic Data
Authors T. Dean, C. Strobbia and D. SweeneyAbstractAlthough the requirement for accurate timing of both the sources and receivers used for land seismic data acquisition has long been known, the numerical requirement for, and impact of, timing accuracy on data quality is poorly defined. In this paper we derive a method for determining the theoretical timing requirement for data acquisition. We then demonstrate the impact of poorly timed data on data quality and examine our ability to remove timing errors in data processing. Source timing variations can be corrected through the application of surface-consistent static correction but only if multiple shots have not been stacked during acquisition. Receiver timing variations are more problematic and the ability to correct for them relies on a sufficiently dense acquisition geometry.

Wellsite Real-Time Geochemical and Petrophysical Logging in North America Unconventionals
By Isaac EasowAbstractHundreds of wells are drilled in North America each year targeting the unconventional resource-rich oil and gas reservoirs across various basins. Each unconventional reservoir has unique and distinct petrophysical and geochemical properties based on reservoir geology and the geological environment of deposition. Unlike conventional drilling and completions, for unconvention-als, traditional logging and evaluation methodologies leave a lot of uncertainities and inconclusive answers to challenging reservoir heterogenities in providing inputs to target selection, well placement, completions and predict production potential. There are various techniques from surface logging methodologies to achieve quantitative results and interpretations. These techniques are non-intrusive and have provided some important and conclusive interpretation in recent years. This article will highlight key formation evaluation techniques that aided operators to drill and complete wells in the Wolfcamp, Bone Spring, Avalon, Spraberry, Woodford, Meramec, Osage, Haynesville, Marcellus, San Andres and Yeso formations.

Compact Phased Arrays for Microseismic Monitoring
AbstractA network of four SADAR® arrays installed at Carbon Management Canada’s (CMC) Containment and Monitoring Institute (CaMI) Field Research Station provides an example of the results achievable through passive monitoring of microseismicity at an active CO2 storage facility. The SADAR arrays, designed as compact volumetric phased arrays, provide a passive, persistent, and permanent data acquisition and analysis capability. Data from compact phased arrays are processed to take advantage of the spatial coherence of the incident seismic signals to increase signal resolution while suppressing noise and clutter signals, and simultaneously providing signal attributes such as angle-of-incidence and phase velocity. The network of arrays allows for automation of location and magnitude determination at a reduced channel count and sensor footprint. We present results from a nine-day reporting period, a subset of the overall compiled seismic event bulletin, chosen because the time span contains both CO2 injection events as well as other non-injection activities. A total of 55 events were detected and located with an Mw = -2.5 threshold. The results demonstrate the promising performance of permanently deployed, networked SADAR arrays to detect and locate microseismicity associated with CO2 storage reservoirs. Technologies such as SADAR will be an enabling driver as industries embark upon gigatonne storage capacities.
