Mongolia development considerations and project economics
Mongolia has been a self-governing republic since 1991. With a population of just over three million people, Mongolia has the lowest population density in the world and the country’s GDP is heavily reliant on the mining sector – the nation’s largest consumer of energy. Coal dominates domestic power generation. However, Mongolia’s land mass and climate also make it suitable for alternatives such as solar, wind and hydro, which are likely to become competing power sources as technology evolves. Liquid fuels dominate the transportation sector and 100% of refined product is currently imported from Russia – there is political imperative to diversify this single source of supply. Currently Mongolia exports 21kbod of crude from Blocks XIX and XXI to refineries in China while importing refined product from Russia. This is expected to evolve over the next five years as foreign direct investment plays a part in developing a domestic downstream industry.
Beyond the geological rationale for exploration in Mongolia, which we discuss earlier in this note, there is a strong commercial rationale underpinned by several unique factors:
■
Low well costs (shallow wells cost just $1-2m while deeper development wells cost up to $4m) drive high expected monetary value (EMV).
■
Low population density – minimal above ground risk but can be a challenge for equipment mobilisation and resourcing.
■
Attractive fiscal terms with PSC cost recovery and 0% corporate tax. Key terms include: royalty at 5-8%; cost recovery capped at 40% of gross revenue; and contractor profit split at 45% to 60% depending on production rate.
■
Significant running room in the event of commercial discovery.
■
Recent increase in foreign direct investment, including Indian state funding for Mongolian refining capacity.

A key consideration for the development of oil discoveries in Mongolia are offtake options, ie the cost of transportation to buyers, be that by truck, rail or pipeline. Given the remoteness of the country’s hydrocarbon basins, pipeline construction and crude transport costs can have a significant bearing on project economics.
Petro Matad has identified several offtake options; we highlight some of these below:
1.
Mongolia refinery: Sainshand. Public announcements made in 2017 and Q118 suggest that plans are underway to construct a 1.5m tonne refinery (30kbd) in Sainshand Soum (district) at a cost of c $700m under a $1bn loan from the Import-Export Bank of India. This project has gained considerable momentum since the new government took office in H217. Crude from Block IV/V could be transported to Sainshand by truck or, if reserves justify, a dedicated pipeline.
2.
China refinery: Yumen. The Yumen refinery in Gansu province is known to have spare capacity and remains an offtake option via truck/railroad.
3.
China refinery: Ningxia. The Ningxia refinery is known to have spare capacity and remains an offtake option via truck/railroad.
4.
China refinery: Baota. The Baota refinery is known to have spare capacity and remains an offtake option via truck/railroad.
5.
China refinery: Hohhot refinery. The Hohhot refinery is known to have spare capacity and remains an offtake option via truck/railroad.

Some uncertainty pertains with regard to the precise cost of various offtake options; we use company data on offtake costs, which are based on data obtained from Petrovis and US benchmarks. We note that company figures exclude the need for heated transport (required if the pour point of discovered waxy crude is high), which could add up to $2/bbl to opex costs. Given the uncertainty around price differentials, offtake options and costs, we have decided to use a conservative $5/bbl discount to Brent as a differential and company guidance on operational costs plus an additional 20% cost contingency.
Suitable development analogues for the development of resource onshore Mongolia include PetroChina’s development of c 160mmbo of resource in Block XIX and Block XXI; however, publicly available data on costs and productivity is sparse. Petro Matad believes that per well initial production (IP) rates range from just 40bod to 300bod, with estimated ultimate recovery (EUR) averaging 0.6mmbo. Given that better reservoir quality is expected in Block IV/V, management expects that in the event of an oil discovery, average IP rates and EUR will be higher than those found in Block XIX and Block XXI.
Edison’s capex cost assumptions are based on management guidance. Key assumptions include a development well cost of $3.9m, facility costs in line with domestic benchmarks and a conservative 40% development cost contingency to reflect engineering being at the conceptual design stage.

As can be seen in Exhibit 14, total full-cycle unit costs range from $16.4/bbl to $33.5/bbl depending on development scenario. We believe these are broadly in line with onshore development analogues in frontier basins. For example, Tullow Oil quotes a full-cycle cost for discoveries onshore Kenya at $25-30/bbl (capex and opex including pipeline tariff).
As a basis for our valuation we estimate NPVs for potential small, medium and large oil discoveries as outlined below:

Conceptual production profiles for the development scenarios highlighted above are provided in Exhibit 15 below. Management assumes that initial production volumes will be used to fill available ullage at the planned 30kbod capacity domestic refinery in Sainshand, which we assume is operational in 2022. Volumes over and above available ullage at Sainshand will be exported to refineries in China via truck and railroad.

Low volume threshold for commercial development
Based on our economic analysis, low well costs make it possible to scale a development to match the discovery resource size. This provides for a very low commercial threshold for oil given management’s current assumptions for well cost. Based on Edison’s long-term Brent oil price assumption of $70/bbl in 2022, we believe the commercial threshold for oil to be c 10mmbbl at $70/bbl Brent long term.

High IRRs provide an attractive farm-out option post discovery
To value individual prospects we generate a relationship between prospect/development size and value per barrel for Block IV/V. Our analysis shows a higher value per barrel for larger discoveries based on our long-term oil price assumption of $70/bbl Brent, rising from $5.4/bbl for a 15mmbbl discovery to $6.5-7.7/bbl for larger discoveries. As can be seen in Exhibit 17, developments generate high IRRs, which should enable Petro Matad to farm-down its 100% equity interest in the event of discovery while minimising value dilution.

Prospect EMVs are robust given low well costs, but commercial risk and uncertainty remain
We add an exploration overlay to our analysis, as decisions to drill are likely to be made on a case-by-case basis taking into account geological, technical and commercial risks, which we combine into our commercial chance of success (Pc). This risking incorporates probability of geological success (Pg) and probability of economic success (Pe). We calculate the expected monetary value (EMV) of an exploration prospect using the weighted value of failure (exploration well costs) plus the weighted value of success.
Petro Matad’s ability to scale development plans proportionally to discovered resource size, combined with relatively low well costs, means that even relatively high-risk prospects and small volumes are expected to deliver a positive EMV.
