Composition of crude oil and natural gas produced from 10 wells in the Lower Silurian "Clinton" Sands, Trumbull County, Ohio

Composition of Crude Oil and Natural Gas Produced from 14 Wells in the Lower Silurian "Clinton" Sandstone and Medina Group, Northeastern Ohio and Northwestern Pennsylvania

“…Crude oils from "Clinton"/Medina reservoirs in this study and in Burruss and Ryder (1998) are characterized by pr/n-C 17 and ph/n-C 18 values that vary broadly with their depth of production ( Figure 16). Major exceptions are sample 14 (#6 Weber) that is grouped with oils produced from much shallower depths and sample 6 (#3 Griffin) that is grouped with oils produced from much greater depths (Figure 16).…”

“…Judging from their isotopic location on a Schoell (1983) diagram (Figure 4), "Clinton"/Medina natural gases from this study and from Burruss and Ryder (1998) are thermogenic in origin. The δ 13 C methane and δD methane values define a straight line that indicates that the gases become isotopically heavier with depth of production ( Figure 4).…”

“…Cross section A-A' , which connects with cross section D-D' in Mercer County, is located 5 to 10 miles from the wells sampled in southeastern Mercer and northwestern Butler Counties (Figure 3). Also located in Figure 3 are 10 wells in Trumbull County for which oil and gas analyses have been reported by Burruss and Ryder (1998). Selected information on the wells sampled for this investigation is listed in Table 1.…”

Age Dating Heating-Oil Releases, Part 1. Heating-Oil Composition and Subsurface Weathering

“…The samples were analyzed with a GC/FID to evaluate n-C 17 /pr ratios. Furthermore, a literature review was conducted to establish n-C 17 /pr ratios in middle distillates and crude oils (Palacas et al, 1982;Collins et al, 1994;Buruss and Ryder, 1998;Porter and Simmons, 1998;Wang et al, 2003;Chung et al, 2004;Environment Canada, 2004;Hurst and Schmidt, 2005;Blanco et al, 2006;Hwang et al, 2006;Røberg et al, 2007). Christensen and Larsen (1993) claim that n-C 17 /pr ratios for fresh heating oil range from around 2.0 to 2.4 (based on Figure 4 of their article).…”

Study of Natural Bitumen of Nagornoye Deposit, Troitskneft JSC (the Republic of Tatarstan, Russian Federation) aimed at Processing Options Determination

“…The most important indicator of oil quality, which determines the processing method, range and performance characteristics of the obtained petroleum products is the chemical composition and its fraction allocation (Altgelt, 1993;Burruss & Ryder, 2013;Speight, 2014).…”
