Abstract
A method for treating a hydrocarbon containing layer in a subsurface formation is described. The method may include removing at most about 20% by weight of the nahcolite from one or more intervals in the hydrocarbon containing layer that include at least about 40% by weight nahcolite. Heat may be provided from a plurality of heaters to the hydrocarbon containing layer such that at least some hydrocarbons in the hydrocarbon containing layer are mobilized. At least some mobilized hydrocarbons may be produced through at least one production well.
