According to CRR, drilling of the well was delayed by a few days due to restrictions on moving larger parts of the drilling rig.
Golden 33-20 is about 1km southwest of Florence in Fremont County and will be drilled to a measured depth of 4926ft.
Australia's Comet Ridge owns a 43.75% stake in CRR, which holds a 97.25% in the Florence project.
CRR was formed from a joint venture between Comet Ridge and New York-based private equity firm Pine Brook Road Partners.
