Our IQP analyzes public data regarding regulatory violations related to the casing and cementing of shale gas extraction wells in the state of Pennsylvania. Computer based data analysis programs including Microsoft Excel and MATLAB were used to generate visual representations of the data, which allowed our group the ability to more easily identify trends. Our group also interviewed experts on the shale gas industry in order to gain a more complete understanding of the issues at hand. These specialists included petroleum engineers from drilling companies such as Range Resources, employees at U.S. government agencies such as the Department of Energy (DOE) and the Environmental Protection Agency (EPA), and academic experts from institutions such as Cornell University. After these interviews and a thorough analysis of the available data, our group recognized and provided explanations for trends in the data. Some noteworthy trends identified by the group included the clustering of violations in the north-central region of Pennsylvania, and the fact that some companies appear to operate with a lower level of cementing and well casing violations. The group also identified specific areas which may need continuing research including the way that well sites are chosen for inspection and the effects of drilling through younger, shallower hydrocarbon formations in order to access the Marcellus Shale. Our final report was submitted to the DOE for use in their continuing research." ; dct:identifier "6c71d68d-eef8-48ff-a9f7-d2c3008f6236" ; dct:issued "2025-11-25T21:54:07.194192"^^xsd:dateTime ; dct:modified "2025-11-25T21:54:07.194195"^^xsd:dateTime ; dct:publisher ; dct:spatial [ a dct:Location ; locn:geometry "MULTIPOLYGON (((-75.6479 37.9703, -75.8654 37.9798, -76.3298 38.0458, -79.4899 39.1974, -79.4810 39.7203, -78.8178 39.7231, -78.0960 39.7255, -75.7911 39.7239, -75.0456 38.4496, -75.0873 38.3231, -75.1728 38.1243, -75.2422 38.0286, -75.6479 37.9703), (-74.2369 40.5060, -79.7617 42.0031, -79.7632 42.2673, -79.0622 43.2682, -75.3289 44.8106, -74.9685 44.9486, -74.7361 44.9929, -73.3447 45.0061, -71.8700 41.0745, -71.9187 41.0306, -72.5212 40.8150, -73.0309 40.6713, -73.2491 40.6254, -74.1936 40.5106, -74.2369 40.5060), (-78.5794 33.8822, -84.3238 34.9891, -84.2910 35.2106, -84.2259 35.2617, -83.8811 35.5107, -81.6698 36.5898, -75.9016 36.5564, -75.8778 36.5560, -75.4566 35.6176, -75.5259 35.2281, -76.5439 34.5880, -78.0345 33.9145, -78.5794 33.8822), (-82.5476 38.4005, -82.5754 38.4039, -83.6785 38.6209, -83.7702 38.6508, -84.1767 38.7885, -84.2287 38.8127, -84.8115 39.1026, -84.8121 39.3030, -84.8110 39.5641, -84.7904 41.6975, -80.5206 41.9869, -80.5200 41.4893, -80.5203 40.8542, -80.5220 40.6372, -80.6045 40.3062, -80.6147 40.2765, -80.8328 39.7034, -80.8811 39.6241, -82.3292 38.4419, -82.4950 38.4058, -82.5476 38.4005), (-79.3966 39.7193, -80.4291 39.7198, -80.5243 39.7212, -80.5260 40.1625, -80.5239 41.4951, -80.5226 41.8508, -80.5206 41.9869, -79.7632 42.2673, -75.3828 41.9984, -75.3457 41.9928, -75.1248 41.8492, -75.0798 41.8141, -74.7400 41.4221, -74.7053 41.3751, -74.7001 41.3506, -74.7255 40.1493, -74.7463 40.1244, -75.1429 39.8816, -75.2537 39.8455, -75.4205 39.7990, -75.7749 39.7246, -75.7911 39.7239, -76.1392 39.7222, -76.5698 39.7203, -77.4758 39.7196, -79.3966 39.7193), (-84.6187 34.9888, -85.2677 34.9892, -89.7173 34.9993, -90.3054 35.0008, -90.2919 35.0485, -90.1728 35.4238, -89.6946 36.2522, -89.5333 36.4982, -88.0713 36.6797, -81.9183 36.6136, -81.6523 36.6077, -81.7093 36.3338, -82.0203 36.1298, -82.0776 36.1003, -84.3238 34.9891, -84.6187 34.9888), (-81.6659 37.2049, -81.8389 37.2855, -82.2956 37.6691, -82.5002 37.9223, -82.6461 38.1463, -82.6472 38.1694, -82.5982 38.3685, -82.5866 38.4125, -80.6677 40.5821, -80.6373 40.6140, -80.6115 40.6201, -80.5220 40.6372, -77.8424 39.6054, -77.7716 39.4981, -77.7372 39.3962, -77.7275 39.3178, -77.8200 39.1417, -77.8307 39.1322, -80.2879 37.5112, -80.4254 37.4349, -80.9679 37.2918, -81.2229 37.2402, -81.5567 37.2064, -81.6659 37.2049)))"^^gsp:wktLiteral ] ; dct:title "Marcellus Shale: Cementing and Well Casing Violations" ; dcat:contactPoint [ a vcard:Organization ; vcard:fn "Deane-Shinbrot, Steven" ] ; dcat:distribution ; dcat:keyword "amerigeo", "amerigeoss", "cement", "ckan", "edx", "energy", "energy-data-exchange", "geo", "geology", "geoss", "global", "marcellus-shale", "task-9", "violations", "well-casing" . a dcat:Distribution ; dct:description "Natural gas extracted from shale formations is one of the fastest growing sources of energy in the United States.
