Some of this material was prepared for presentation at the ADIPEC 2013 Technical Conference, Abu Dhabi, UAE, 10-13 November 2013 in a presentation titled “A Consistent Approach to Source Rock Resource Evaluation and Optimization.” This is the first in a series of five blog entries on the subject. The commercialization and widespread development of shale [...]

Sweepscan improves waterflood performance

Analyzing Waterflood Communication: In this month’s blog, Baker Hughes reservoir engineering consultants Shelia Marsh and Atul Kshirsagar contribute to the blog. I also appreciate Neil Meldrum and Edwin Jong’s input. One key to optimizing oil recovery and determining production potential of waterflooded fields is through reservoir surveillance. Geological studies alone cannot quantify potential increases in [...]

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 [...]

Living in Asia the last year and a half has been a particularly edifying experience for my wife and me. I began writing this article in Hyderabad and am finishing it in Ulaanbaatar. I have been fortunate to have traveled much of the world in my life but living in Hong Kong and working on [...]

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. [...]

For this blog entry I continue to quote from a White Paper prepared by Baker Hughes and available on our website. The complete paper can be obtained here. I will present it here in three parts. Minimizing risks with responsible fluids No regulatory body has documented a single case of fracturing fluid contaminating fresh water [...]

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 [...]

After a long hiatus we are now returning to the series on oilfield economics. Discounted cash flow return on investment (DCFROI) also referred to as discounted cash flow rate-of-return (DCFROR) or Internal Rate of Return (IRR) is defined as the discount rate at which the NPV is zero. It is very attractive to decision makers [...]

In this, the final of three blog entries about formation testing, I will cover the use of FTs for fluid identification and some advanced applications.  In a demonstration that Baker Hughes employees occasionally do to illustrate these capabilities at trade shows we will actually pour either Coca-Cola® Diet Coca-Cola® into the tool and differentiate the two based [...]

In the prior blog entry we discussed the tools and interpretation theory for formation testers.  In this entry we will talk about using FTs for a unique aspect of reservoir characterization that can only be done commercially during the drilling phase of a well and before its completion.  The next blog entry will discuss fluid [...]
