The Michigan basin is a classic intra-cratonic basin that initiated its formation in the late Cambrian period. The depression is filled primarily with Cambrian-Ordovician around the margins and Silurian-Devonian basin-ward with Mississippian and Pennsylvanian composing the basin's center. A fine layering of Jurassic strata exists on the basin's central surface. This basin has seen active research in the previous decades primarily showing an interest in oil and natural gas exploration in the Cambrian sands and carbonates. The Michigan basin is a strong indicator of what one may find in the strata beneath Michigan and, though the geology exists in the region to suggest reservoirs of hydrocarbon resources they simply do not exist in the quantity to make major economical plays. This is supported by a number of failed drilling attempts that have not produced resources to be worth the attempt. The processes that characterized these finds are the focus. Seismic reflection was an early process that outlined the basin formation. It characterized the broad, gentle slopes requiring little data migration for interpretable data. Drilling interests led to seismic surveys. The survey was conducted using lines of seismic geophones and high energy pulses (dynamite) to reflect deep enough to interpret the cause of a gravity anomaly in the mid-Michigan area. The bedrock below the center of the basin was found to be the cause and borehole drilling characterized it as a Precambrian basement. Although the Michigan basin appears to be an formation with economic resources, seismic reflection studies and failed drilling have proven that, though containing marked features geologically, sufficient volumes do not exist.

The Michigan basin is a classic intra-cratonic basin that initiated its formation in the late Cambrian period. The depression is filled primarily with Cambrian-Ordovician around the margins and Silurian-Devonian basin-ward, with Mississippian and Pennsylvanian composing the basin's center. A fine layering of Jurassic strata exists on the basin's central surface this sentence feels unfinished, making the lead-in to the next feel choppy and awkward. This basin has seen active research in the previous decades primarily showing an interest in oil and natural gas exploration in the Cambrian sands and carbonates Suggested rewording: Active research in the previous decades have shown a primary interest in oil and natural gas exploration in the Cambrian sands and carbonates of the area. Paragraph break The Michigan basin is a strong indicator of what one may find in the strata beneath Michigan and, though the geology exists in the region to suggest reservoirs of hydrocarbon resources, they simply do not exist in the quantity to make major economical plays. This is supported by a number of failed drilling attempts that have not produced resources to be worth the attempt Suggested rewording: The fact that a number of drilling attempts have failed to produce the desired amount of resources supports this.. The processes that characterized these finds, however, are the focus the focus of what, Lat?. Paragraph break Seismic reflection was an early process that outlined the basin formation. It characterized the broad, gentle slopes requiring little data migration for interpretable data (These first two sentences feel out of place upon reading further, but perhaps it's because I'm fairly unfamiliar with geology and how 'seismic reflection' may affect the beginnings of drilling interests, but this seems like it may belong -after- talking about drilling interests). Drilling interests led to seismic surveys. The survey was conducted using lines of seismic geophones and high energy pulses (dynamite) to reflect deep enough to interpret the cause of a gravity anomaly in the mid-Michigan area. The bedrock below the center of the basin was found to be the cause and borehole drilling characterized it as a Precambrian basement. Although the Michigan basin appears to be an a formation formation with economic resources, seismic reflection studies and failed drilling have proven that, though containing marked features geologically, sufficient volumes do not exist.

okay, over all, not bad, but it jumps around a lot. I suggest finding and grouping like ideas. As it stands now, the work and evidence is there, but feels disjointed when looked at as a whole.
