Understanding the Lifecycle of Oil Wells

Key Takeaways:

• Oil industry investments can offer potential high returns but also carry significant risks.
• Returns on oil industry investments are lagging due to high capital requirements and inconsistent oil production rates.
• The lifecycle of oil wells includes Exploration, Development, Drilling and Completion, Production, enhanced recovery and abandonment.
• Assess the financial and operational health of companies involved in oil extraction to make informed investment decisions

Exploration

The exploration stage is the initial phase of the oil well lifecycle. During this phase, oil companies seek out and assess potential oil and gas reserves for production. Geological mapping and seismic testing are performed by geologists as part of the exploratory phase of oil production to identify geological areas with oil resources and to approximate the amount of oil that could be produced from those areas.

While exploration of potential oil fields can provide information to identify oil fields, not all exploration projects will result in successful identification of an actual oil field and therefore represent the highest risk in the petroleum exploration and production lifecycle. Therefore, investors should assess the likelihood of success of the proposed exploration prior to making investments in exploration projects.

Development of Oil Fields

The development of oil fields follows the successful identification of oil and gas reserves associated with the previously identified oil fields. Upon completion of the explorations, the next phase of the oil well lifecycle will be development where infrastructure for producing, processing and delivering oil is constructed and additional wells are drilled. The development phase also includes identifying the most efficient methods of extracting oil such as horizontal drilling and hydraulic fracturing.

The development phase requires substantial investments in drilling for oil and gas reserves and the construction of infrastructure to transport oil and gas from the wells, and the technologies associated with drilling and extracting oil and gas. Development phases can take many years from the drill date before the reserves will have produced oil for sale. Thus, investors should consider both their investment horizon and the likelihood of delays in receiving the expected return on investment from their investments post exploration because these can occur in both the exploration and development phases of the oil well lifecycle.

Drilling and Completion

In the drilling and completion phase, the oil is extracted from the wells through holes drilled using the drilling rigs. An oil well can be drilled using various drilling processes, such as Vertical, Directional, and horizontal. And when the well is drilled to the ideal depth, it’s considered to be ‘Completed’.

Drilling wells incurs high expenditure on labour, equipment, and fuel. As an investor, you must evaluate whether the expected oil production rates justify the costs. Certain drilling techniques, such as hydraulic fracking and horizontal drilling, can reduce costs and increase production rates but they may face regulatory or environmental issues.

Production

Oil is taken out of the reservoir after a well is drilled and finished. The size of the reservoir, the geological features, and the technology employed all affect the oil well's production rates.

At this point, oil extraction begins to bring in money, giving the investor a return. To ascertain the well's capacity to generate profits, it is crucial to evaluate operational expenses like labor, maintenance, and transportation. Production rates will drop as the reservoir shrinks, yielding poor returns. Investors need to plan for low returns and take into account the anticipated decline in production.

Enhanced Recovery

Enhanced oil recovery (EOR) techniques are used to boost the well's output and prolong its life when oil production begins to decline. To push the oil toward the surface, EOR techniques include chemical injection, gas injection, and water flooding.

EOR methods can be expensive, necessitating further capital expenditures for new machinery and technology. Investors need to think about whether the higher production rate makes the EOR expenses worthwhile.

Abandonment

The last stage of an oil well is abandonment. At this point, the well’s reserve has been depleted or the production has become unprofitable, and it can no longer continue producing oil or gas. Decommissioning the facility now takes place along with blocking and preventing the escape of oil or gas through the well, and rehabilitating the land in accordance with environmental regulations.

During the abandonment stage, there will be no further production of oil or gas from the well and thus there ceases to be any revenue from the well. Additionally, if the well does not produce at the anticipated level, then the investors need to understand the timeline for abandonment and the potential financial impact of the abandonment process. In addition to the financial performance of the oil well investments, companies will also need to evaluate their decommissioning costs in order to accurately assess their overall financial performance, and they will need to ensure compliance with all applicable environmental regulations to avoid being subject to fines and penalties.

Should You Invest in the Oil Industry?

Investing in oil is a lucrative way to generate returns and can be risky at the same time. Before making an investment, it’s important to understand how oil wells work. Performing due diligence is also essential before making an investment in oil wells, because this will allow you to make better-informed decisions about the potential profit, risk, and cost of acquiring oil wells at each stage in the acquisition process.
