The Importance of Petroleum Economic Evaluation and Risk Analysis

An oil platform


In today’s volatile oil price environment, the analysis of risk in an economic evaluation of an upstream oil and gas investment is absolutely crucial. Corporate/asset acquisitions and disposal, acreage bidding, exploration drilling evaluations, field development decisions, equipment purchases, lease / buy decisions, fiscal negotiations and so on all require comprehensive economic analyses.


The complete economics analysis will be based first of all on detailed after tax cash flow analyses incorporating full fiscal effects, the assessment of economic indicators and detailed probability analysis. Such analyses are now standard in the evaluation of investments in today’s international upstream oil and gas industry.


If you want to be able to perform this analysis and learn how to:

  • Value oil and gas properties
  • Construct petroleum industry cash flow projections.
  • Calculate and know how to apply economic indicators.
  • Perform risk analysis to exploration & production investments.
  • Evaluate and model fiscal/PSC terms of countries worldwide.

Here is the course which you may want to attend:

8 Facts About Bakken Shale Oil


  1. Bakken Shale oil is name after the Bakken Formation, a series of geological layers of shale, siltstone, and sandstone underlying parts of North Dakota, eastern Montana, and southern Saskatchewan. The 360-million-year old formation is up to two miles below the surface, but is itself very thin, generally less than 100 feet.
  1. Bakken Formation holds huge amount of oil and gas. In the entire Bakken Total Petroleum System, which includes another rock layer called Three Forks, the USGS estimates that there are 7.4 billion barrels of technically recoverable oil. In addition to the oil, the formation contains 6.7 trillion cubic feet of natural gas.
  1. The oil contained in the Bakken is not easy to extract due to the low permeability of the rocks and the thinness of the deposits. To stimulate production, horizontal drilling and hydraulic fracturing are used to create pathways for the oil to flow from the tight rocks into the well bore.
  1. Crude oil production surged from 100,000 barrels a day in 2007 to more than 1.1 million barrels a day in 2014. Current production is about 1 million barrels per day.
  1. Thousands of wells have been drilled since 2007. Currently the number of wells is around 13,500.
  1. Crude oil from the Bakken Formation is more volatile than many other forms of crude oil.
  1. The number of active rigs in the state’s oil patch was 39 in February 2017. It increased to 51 in April 2017 – an 18 percent increase since February.
  1. According to Platts analytical data, breakeven prices in the Bakken shale play fell to $33.53 a barrel in April 2017, from $37.91 a barrel in the same month last year. According to Arthur Berman, 10% of the reduction is due to advancement in technology and 90% is due to lower costs in equipment and services.

What is your conflict management style?

Untitled design

Conflict is defined as a situation where your concerns or desires differ from another person’s.

People tend to have a preferred conflict resolution style, but may use different methods in different conflict situation. Therefore, it is important that you realize the styles you use in resolving various conflicts you face.

Here are the common 5 styles people use in resolving conflicts.

  1. Avoiding Style

In this style, you are unassertive and your approach is uncooperative. You probably feel neither your personal goals nor the relationship with the other person is important.

You probably adopt this avoiding style when there is no urgency to resolve the situation.

Results: No win No win

  1. Accommodating Style

In this style, you are cooperative yet your approach is unassertive. You probably give in to maintain the relationship with the other person, but your personal goals are sacrificed.

You probably adopt this style because you want to preserve harmony and avoid disruption.

Results: Small win Small win

  1. Compromising Style

This is a cooperative approach. In this style, you value your personal goals and your relationships with the other party. Here you are willing to give and try to get concessions from the other party.

You probably use this style when you and the other person have equal power and you want to achieve temporary settlement for complex issues.

Results: Medium win Medium win

  1. Competing Style

This is an uncooperative approach. In this style, you seek to achieve your personal goals at the expense of the relationship with the other person.

You probably use this style because a quick and decisive action is vital, or when you feel you must get what you want.

Results: Win Lose

  1. Collaborating Style

This is an assertive and cooperative approach. Here you and your counterpart both try to resolve the conflict by open and direct communication.

In this style, you and your counterpart want to achieve a win-win outcome and desire to maintain good relationships with each other.

Results: Win Win

So, are you an avoider, accommodator, compromiser, competitor or collaborator?

It is important that you understand these 5 styles. By knowing the consequences of each style, you will be able to apply these strategies in different conflict situations to achieve the results you want.

The Future is Bullish for LNG


The Asia Excellence, one of six new LNG vessels in Chevron Shipping’s fleet, delivered the first cargo of LNG from the Gorgon Project to foundation customer Chubu Electric in Japan in 2016.

“Natural gas is truly becoming a globally traded commodity, and the future is bullish for liquefied natural gas (LNG),” according to Mike Wirth, Chevron vice chairman and executive vice president of Midstream and Development. With LNG demand projected to grow by roughly two-thirds over the next decade, he says, “It’s an exciting time to be a part of this industry.”

“Asia alone will be responsible for nearly 50 percent of expected global LNG demand growth over the next decade.”
