Many of us now realize this is not necessarily true. Actually, if we believed this concept, we might have missed a lot of big important petroleum discoveries. Below are some examples that contradict the theory:. What is interesting to me is that the reservoir was merely deposited. 300 °C, and the reservoir contains low maturity oil! 2) In deep water G...

Surface temperature is the boundary condition for our thermal/heat flow models. The "state of the art" approach to estimating surface temperature involves the following:. 1) a function that relates sea level surface temperature to latitude,. 3) a correction of surface temperature with water depth (or elevation). If you are concerned now, that is only...

Paradoxical observation, nevertheless, is that in most margins the extension measured from normal fault throws appears to be much smaller than that inferred from subsidence and gravity modelling,. Thus implying ubiquitous upper-plate rift margin settings (the “Upper Plate Paradox” Driscoll and Karner, 1998; Davis and Kusznir, 2004). The figures ...

In the follow hypothetical case we have 4 prospects in an area, each having the exact same geology (fetch area, geometry, migration distance, and complexity of the carrier beds, …), with the only exception the estimated expulsion volumes in each of the fetch areas are different as shown below because source variability.

The Petroleum System Blog: Shale Plays Need Seals Too
http://petroleumsystem.blogspot.com/2015/06/shale-plays-need-seals-too.html
The Petroleum System Blog. Technical discussions on petroleum system modeling. Sunday, June 7, 2015. Shale Plays Need Seals Too. In an earlier post. I argued that there may be significant lateral migration within shale reservoirs that can lead to higher maturity fluids produced from lower maturity areas, and even. Dry gas production in the oil window. In this post, I would like to propose that shale reservoirs also need seals to work. As saturation in the reservoirs builds up due to continued generation,...

The authors conclude that the transient effect is smaller than that caused by radioactivity within the sediments. You may click on the image to see a version with better resolution. Basal heat flow decreases to 48 mW/m. At the end of the erosion period. This indicates a ±12 mW/m. In recently uplifted parts of North Africa, ...

This figure shows how sedimentation rate affects heat flow. It is based on a simple 1D basin model, with a steady-state initial thermal condition. A shale (with typical shale properties assumed by basin modelers) layer is deposited between 100 and 99 million years ago followed by a hiatus till present day. Posted by The Beta Factor.

Unfortunately, the answer is often "not very useful at all". Here are some published data for several wells in the Bozhong sub basin of the Bohai Basin (courtesy of a literature search by Zhiyong: Guo et al., 2011, Fig. 1b). Not all data sets are like this of course and one could propose various reasons for the scatter observed ...

The Petroleum System Blog. Technical discussions on petroleum system modeling. Tuesday, June 2, 2015. Dry Gas, Wet Gas, Condensate and Condensables. Wet vs. dry gas definitions and terminology can be confusing so I thought it might be worth posting a summary here. Firstly, let's look at the composition of a typical gas condensate:. This one is from the textbook on the phase behaviour of reservoir fluids by Pedersen and Christensen (2007) . When speaking of wet vs. dry gas in the conventional E and P ...
