This dummy valve is “smart” Gas lift is an artificial lift technology that uses gas injected (generally) from the surface through an opening in the production tubing to lower the density of the liquid column, allowing the well to be produced. In most modern completions, gas enters through one or more gas lift valves placed […]

I recently had the opportunity to address a large group of materials scientists and engineers who work for Baker Hughes. I attended a few of their talks during the two-day conference and I was impressed with how complex and sophisticated the technologies involved are. While this blog is dedicated to reservoir issues I decided to […]

Deepwater exploration, development and production present unique challenges to operators. Safe operations and protecting the environment are primary requirements. Minimizing risks and maximizing recovery are also among their top priorities. With average worldwide rig day rates remaining higher than $300,000 (drillships and semisubmersible rigs), there is no room for unexpected costs resulting from nonproductive time. […]

I collect knives. Custom made knives, hand crafted out of exotic materials by some amazing artists. One of my knives has a bolster made of superconducting[1] materials including such unusual elements as yttrium, bismuth, thallium and strontium. Young professionals may not remember the buzz in the industry when scientists discovered superconducting properties in materials at […]

There is a lot more to this subject than is covered here in one blog post. Essentially this is what I think the petroleum engineer as an analyst needs to know. It is far from the level of understanding needed to calculate WACC and many of its applications. Conceptual Framework Several concepts of financial theory […]

Present Value Ratio (PVR) While NPV fails to deliver a measure of capital efficiency, the Present Value Ratio (PVR) index calculates a measure of investment efficiency that is very useful in ranking projects with significant capital investment. It is the ratio of the discounted (after tax) net cash generated by a project to the discounted […]
