The current series of Tech Talks is aimed at discussing, in gradually increasing detail, where we are, and will be getting our oil and natural gas from over the next two decades...

Gail Tverberg’s analysis of some of the underlying causes of the current Egyptian crisis is cogent, but one of the other consequences caught my attention today...

In the last two Tech talks I have been discussing the production of heavy oil from the deposits in the Orinoco Basin in Venezuela. Production of that oil requires, in part, the injection of large quantities of natural gas....

Last week I wrote a little about the planned production of heavy oil from the Orinoco Basin in Venezuela and used that as the basis for a discussion on API gravity and refinery gains...

Because the world market is increasingly having to accommodate crudes that are heavier and less easy to refine into desirable, profitable products I thought I would revisit my discussion from earlier in the series about...

Just before the Christmas break the United Kingdom was going through some concerns over natural gas supply. Stored gas levels were falling and the National Grid posted a “Gas Balancing Alert” for only the second...

I have written about the limitations in the free flow of oil because of the increasingly heavy and sour nature of the reserves that are now being developed, and the need for suitable refineries to process that oil...

There are two figures that keep cropping up when folk write about the production of oil, one number is the daily flow rate for crude oil, and while the EIA report that the peak production year to date was in 2005, when the...

This is the second in a series I am just starting on oil production and consumption around the world. While it is going to focus more on individual nations and oil fields, over time, there are some general remarks that I...

There is an aspect of coal mining that gets relatively little attention, even though it is growing in popularity, It is with this method that I will conclude this series on mining, and its precursor on oilwell production...

There is a growing concern, as fossil fuels are recovered from the ground, that the cost of the energy required to extract and process them is rising, and that a point may be reached where it is no longer energy-cost effective...

I have been discussing the technologies for oil well drilling and coal mining for quite some time, and am thinking that with that review available and just about complete, it might be time to switch the focus of these Sunday...

Last time I wrote about grouting of ground in order to either strengthen it, or to stop water flowing through it. Grouting is something that is often carried out during the driving of the tunnel or shaft, so that the effects...

For the last two technical talks I have been explaining how, by bolting rock layers around an opening, spraying concrete on the walls of the opening or a combination of both, one can stabilize openings underground...

This is part of a Sunday series of tech talks, on various energy-related technical subjects. Last week I was talking about building tunnels, and tunnels need roof support.
