A seismic attribute is a transformation of the original seismic data that can help determine the rock type and fluid characters. AVO attribute analysis is a proven method for confirming seismic amplitude anomalies associated with gas anomalies. AVO analysis examines the intensity of seismic reflections at varying source-receiver distances (offset). The major risk with AVO analysis is whether seismic amplitude anomalies represent commercial or non-commercial gas accumulations. Combining AVO and absorption attributes using ANN reduces this risk. Further risk reduction is accomplished thorough investigation of the different types of absorption attributes and enhancing the ANN training with petrophysical information derived from well logs. We demonstrate that the high frequency content of the seismic response attenuates more as it propagates through gasbearing reservoirs and, unlike AVO, the absorption attribute is impacted by the amount of gas saturation. Furthermore, we demonstrate how the correlation between shallow gas and shallow seismic amplitudes improves as we include different types of well logs with proper calibration. The ANN, trained by the suite of logs and different frequency-related attributes, enhances the ability to detect undeveloped pockets of shallow gas. Gas has a very marked effect on both density and neutron logs, resulting in lower bulk density and lower apparent neutron porosity. Therefore, combining neutron and density logs and training neural networks based on the well logs with AVO and AQF attributes, instead of just training based on attributes alone, increases the certainty of suspected gas pockets. The real power comes from being able to tie absorption and AVO anomalies with other frequency attributes. Copyright 2012, Society of Petroleum Engineers. Source

Poor indoor air quality (IAQ) is highly correlated with asthma and other respiratory illnesses. As a chronic lung disease, asthma can have significant impacts on the respiratory system and other complications in large populations of the young, the elderly, and the infirm. This disease is associated with various environmental triggers in indoor environments including schools and homes. Reducing these sources of asthma triggers can lead to improved health outcomes in children. Environmental triggers of asthma and other respiratory illnesses can be reduced by systematically identifying and evaluating their sources and then developing a plan of action to prevent, control, and eliminate them. This article presents a step-by-step framework including easy-to-adopt strategies to support the development and implementation of an IAQ improvement and management plan for schools in semiurban environments with a focus on Tangipahoa Parish, Louisiana. The framework presented here encourages outreach, training, and consultations as key parameters for implementation of a sustainable IAQ program. © copyright 2013, national environmental health Association (no refunds).

Grand Bay field has yielded in excess of 250 million hoc since 1938 and is still going strong. Recent reprocessing of Saratoga's proprietary 3D seismic data has allowed mapping of deep potential similar to other deep shelf and ultradeep plays farther west such as Davy Jones with over 1 billion boe of potential. Reservoir presence is the most significant predrill risk, but reservoir quality is expected to be good due to secondary enhancement and geopressures. Drilling cost estimates suggest that these treasures can be commercially attractive and brought to production quickly due to their proximity to Saratoga's existing infrastructure. Source

The shallow Plio-Pleistocene gas play appears to have been largely neglected in southeast Louisiana despite a number of successful completions. Oil companies have not pursued this play because of low historical gas prices, small pool sizes, and increased costs related to compression and gravel pack completions. Other factors relate to the poor seismic imaging of the shallow section and lack of logging. Saratoga has demonstrated that this play can be pursued economically by careful seismic analysis, cased-hole logging, and taking advantage of existing field infrastructure. While such shallow gas reserves are small in size, they represent a "lagniappe" to operators such as Saratoga, focused on more traditional development options but in need of gas lift gas to enhance oil production or to simply develop it commercially in its own right. While we have recognized about 50 bcf potential in and around Grand Bay, we would expect that this shallow gas play is ubiquitous and likely exists elsewhere in all of Southeast Louisiana with a very rough estimate of up to 1 tcf of potential for all fields between surface and 5,000 ft. Our 50 bcf estimate does not cover all the fields in Fig. 3 or Table 1 in Part 1 but only Grand Bay plus portions of Coquille Bay and Main Pass 47. Source

There have been a number of successful completions of shallow Plio-Pleistocene gas in Southeast Louisiana at depths of less than 3,500 ft. The play has been largely ignored, however, due to historical lack of gas demand, increased costs for compression and completion, poor seismic imaging, and lack of logs to evaluate. Numerous shallow gas prospects have been identified at Grand Bay with potential for up to 50 bcf of undeveloped, shallow Plio-Pleistocene gas that will be targeted through recompletions and with the drill bit in the next 2-3 years. Saratoga spent a lot of time and effort reprocessing its 90 sq mile proprietary 3D seismic survey at Grand Bay in order to better image shallow seismic events above 1 sec TWTT in order to tie seismic amplitudes to known shallow gas pay. Shallow gas anomalies often have an amplitude variation with offset (AVO) response and attenuation, which is a gradual loss in intensity of seismic energy. Source
