Onshore well - oil/gas (onshore well production)

The activity generating the emissions is onshore well production, oil/gas. The reference product is onshore well, oil/gas. 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 reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity. Please refer to the ecoinvent documentation here for full details: https://ecoquery.ecoinvent.org/3.11/cutoff/dataset/4740/documentation.
