Also gas analysis is performed real time at the cutting head. They see real time c5 methane shows and the software calculates volume.
Seen this in action on a drill they have a dedicated operative who sits in front of a screen and a time line of various gas shows is created with the data sent to multiple screens around the drill site and via satellite.
Watch the sp nearer the time of expected gas shows.
Got a feeling this will rocket soon
nice update CoMan
Gives food for thought and an insight and further avenue of learning for most on here.
to answer your question regarding the topics in the article;
1) Rock Cuttings are analysed real time on the rig by the Geologist - cuttings are circulated out the well while drilling and samples collected and analysed continuously
2) Mud logs are constructed from the geologist's interpretation of the rock cuttings, these logs show the formation that has been drilled combined with other parameters such as gas levels in the mud that is circulated while drilling (Mud is required to make sure the hydrostatic pressure in the well is higher than the pressures in the formation to prevent the well flowing out of control, its continuously circulated while drilling and also carries the cuttings out) plus a log of drilling parameters while drilling. They are continuously updated while drilling and a very useful record of what's going on while drilling the well.
3) Analysing core data is likely to take months but is not critical to ascertain if the well is a success or not, the information is more relevant for developing a development strategy in the longer term if the wells a success. I'd be surprised if they core this well, its becoming more normal to core an appraisal well when you know you have success rather than commit additional costs to an exploration well where you may not have success. They have the option to take small sidewall cores while doing the wireline logging.
4) Well logs are obtained from the wireline logging tools that are run in the well, they will be analysed by the geophysicists and geologists before the rig has even completed the abandonment phase after the logs are run. Its normal now to run logging while drilling tools (LWD) in the drill string while drilling so a lot of information regarding rock properties, fluid content etc will be available while drilling and prior to the geologist on the rig actually seeing the samples.
5) DST - these drill stem tests are usually performed to establish further reservoir properties, pressures, flow rates from the well etc. A lot of this information can now be obtained with more advanced wireline logging tools. I'd be surprised if they do a DST on this well, again it makes more sense to do it on an appraisal well where you are pretty sure of success rather than commit high costs to an exploration well and then not require the tools etc to do the DST if it is a failure.
6) Reservoir fluid samples will be taken when running the wireline logging tools, the fluid analyser in these tools coupled with other data obtained while logging (formation permeability, fluid mobility etc) will give them a very good idea of fluid properties. I'm not entirely sure how long it would take to get the full lab analysis on the samples but I very much doubt they would require lab data to know if the well is a success or not - that is not normal. If they do a DST then they would also take samples and also fairly quickly have a good understanding of fluid properties while doing the test -
