 The Multiphase Journey: Why You Can’t Separate the Reservoir from Surface Facilities Think about the last time you opened a shaken bottle of soda. You don’t just get liquid; you get a chaotic, fast-moving explosion of gas bubbles and foam. Now, imagine that exact same chaotic mess happening inside a steel pipe that is thousands of meters long, buried deep underground, under massive pressure and shifting temperatures. Welcome to the world of multiphase flow. In petroleum engineering, we rarely, if ever, pump just "oil." We pump a complex, moody mixture of oil, gas, water, and sometimes solid sediments. For decades, the industry treated this as two separate problems. The reservoir engineers cared about getting the fluids to the bottom of the well. The facilities engineers took over once the fluids hit the surface. But here is the catch: the physics of what happens in the dirt completely dictates the physics of what happens in the steel pipelines at the surface. You cannot opti...

Engineering Decision-Making Under Uncertainty: Why Every Petroleum Engineer Needs More Than Accurate Calculations Every petroleum engineer at some point in their career comes to terms with the fact that they will have to make important decisions long before all of the answers appear. Engineering Decision-Making Under Uncertainty Decisions, such as whether to complete a well immediately or defer the completion to gain more insight on the well's potential. Decisions, such as whether a well's production decline is transient or a permanent loss of production. Decisions, such as whether to increase the choke size to improve production, or if that decision would lead to faster water production, and cause a premature abandonment. However, the reality is that most of these decisions do not always have clear cut answers. A petroleum engineer should not be penalized for making a decision in the face of uncertainty, because that is the environment petroleum engineers work in. Uncertainty ...

  Why Reservoir-to-Surface Integration Matters More Than Ever in Petroleum Engineering This article is part of a series inspired by the book Petroleum Engineering: From Reservoir to Surface in the Context of Engineering Decision-Making Under Uncertainty. Petroleum Engineering: From Reservoir to Surface in the Context of Engineering Decision-Making under Uncertainty Petroleum engineering is a very specialized field. Reservoir engineers, drilling engineers, production engineers, process engineers, and facilities engineers all bring the critical skills to developing and operating an oil or gas field. While specialization has greatly moved the industry forward, there is one issue it created: in many cases, engineering decisions are made with in disciplines rather than at a systems level.  It takes more than optimizing a individual part to develop a modern field.  Decisions about the reservoir have a ripple effect on well performance, production system performance, facility pe...
