This data-file estimates the CO2 intensity of drilling oil wells, in our usual units of kg/boe. The calculations are conducted bottom-up, based on fuel consumption at onshore, offshore and deep-water rigs; plus drilling days and typical resource volumes per well.
Drilling wells is not the largest portion of the oil industry’s total CO2 intensity. Nevertheless there is a 50x spread between the best and worst barrels, which is wider than other categories we have screened.
Prolific fieldswill have the lowest drilling-CO2 intensities, particularly where they are onshore (e.g., Saudi Arabia). Infill wells at mature deepwater fields may have the highest drilling-CO2.
This database covers all 14 subsea separation projectsacross the history of the oil industry, going back to the “dawn of subsea” in 1969.
For each example, we tabulate the asset, region, operator, water depth, process technology, Service company, start-up year, power rating, oil capacity, gas capacity, water capacity and some notes.
What is interesting about the data is how elusive the technology’s ascent has been. Two of our projects were cancelled. The largest were 2.3MW. Subsea Boosting and Compression has been 4x more prevalent (chart below).
This matters for the Mero pre-salt fieldwhere an unprecedented, giant, 6MW subsea-separation project is being pioneered, to handle high gas and CO2 cuts.
This data-file tracks the construction progress of 30 FPSOsthat are being deployed in the Brazilian pre-salt oil province. In each case, we quantify the vessel’s oil and gas handling capacity, development timing and recent news.
We also compare the FPSOs’ gas-handling capacity with regional pipeline capacity. There will only be room to monetize one-third of the pre-salt’s produced gas volumes by the mid-2020s. The rest must be re-injected (chart below).
This data-file tracks the Lula oilfield, well-by-well, FPSO-by-FPSO, aggregating data from over 100 production reports, which are published monthly by Brazil’s national hydrocarbon regulator.
Hence we have formulated “production forecasts” for each FPSO, and for the entire field; in 2H19 and in 1H20. This matters for oil markets; and for pre-salt producers, such as Petrobas, Shell and Galp.
Our outlook is for slowing growth, due to rising water- and gas-cuts, which are reviewed well-by-well. One FPSO is now definitively constrained by gas-handling capacity. Another is off-plateau due to maturity. Six Lula FPSOs are now negotiating water-cuts, as shown in the data-file.
1H19 production was lower than expected, at just 72% of total installed FPSO capacity. Our notes attribute the drivers, and contextualise the growth ahead.
The CO2 content of gas fields is going to matter increasingly, for future gas development decisions: CO2 must be lowered to 50ppm before gas can be liquefied, adding cost. Moreover, it is no longer acceptable to vent the separated CO2 into the atmosphere.
Large, low-CO2 resources like the Permian, Marcellus and Mozambique are well-positioned to dominate future LNG growth.
This data-file tabulates 30 major gas resources around the world, their volumes, their CO2 content and how the CO2 is handled.
