Description
One of the greatest revolutions in the history of the oil and gas industry has taken place over the past decade. This revolution is the rise of the shale reservoirs. Initially, these shales were developed using statistical drilling methods in which a large number of horizontal boreholes are drilled throughout the play. Until recently, gas prices supported the economics of this approach. Because of their success, an abundance of gas has caused a decrease in gas price and a new economic paradigm has emerged: shale sweet spot drilling. Sweet spots result from certain geologic conditions, such as increased matrix porosity or total organic content, increased microfractures, and areas with increased brittleness. These reservoir characteristics affect the physical rock properties that, in turn, affect a passing seismic signal. The ability to locate these sweet spots before drilling significantly affects the economics associated with these plays.
