Onshore well - oil/gas (onshore well production - oil/gas)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This is an immobile infrastructure representing the drilling of an onshore well for oil or/and gas extraction. The infrastructure represents all the types of onshore drilling. The rotary drilling method is predominantly used in wells for finding and producing oil/natural gas. The drilling activity requires land for both work and disposal. While the work area can be held relatively small at around 0.2 ha the disposal of drilling waste requires more space. Additional land is used for roads that need to be established as the wells are often located in remote areas. Here a conversion of 90m2 per meter of drilling depth is expected and with a 2-month construction period the use of 15m2a/m. The process includes all energy uses materials and emissions for drilling of an offshore bore hole and finishing of the well. No differences depending on depth of sea and type of geological formation are taken into account. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
