Anyone have info on drilling to monitor gas pressure away from actual well?

I talked to my neighbor yesterday and he told me that they are fixing to drill between our houses to monitor the gas pressure on the well that they are fixing to start drilling.  Granted there is over a quarter of a mile between our houses, but I was wondering what this will be and if anyone had heard of it before.

I think your neighbor may be confusing a "monitor well" with something to do with "pressure".  When completing (fracking) a horizontal well, a monitor well is used for "micro seismic" monitoring of the fractures created in the formation.  By observing the creation of the fractures being induced in real time, the completion crew can adjust their pumping regime to get the spatial frac cylinder that is intended.

It would be of interest if you or your neighbor could get more detail.  There is new approach to drilling multiple wells as a group called "cube" development.  This is used where there are a group of closely located horizontal wells being drilled and completed over a relatively short period of time.  Operating companies want to get the maximum recovery of hydrocarbons without having too much "communication" between wells (frac cylinder overlaps).  This approach does use "pressure walls" or undrilled slots or uncompleted wells between wells undergoing completion operations.  I know this approach is being employed in the Permian Basin but have not read anything about it being used in the Haynesville Shale Basin as yet.

I think that you are correct and I had the wording wrong.  We are just East of 2 wells that just came on line,(Titan), and we will have 2 wells that they are supposed to start drilling this month (Vulcanadon) and then there is one well to the East of us (Velo) that should be online soon or may be on line already.  Our wells will be the Vulcanadon and they are supposed to have a second set of wells for Vulcanadon but I have not seen the paperwork filled for it yet but the title searches for it should be done by now. 

I may be wrong but I think he said that this would not be real deep, 300 ft is what I think he said.

Sounds like a micro-seismic monitor well. 

Microseismic Interpretation

Improve well economics with microseismic monitoring

Schlumberger petrotechnical services collaborate with operators on understanding hydraulically induced fracture system geometry, and temporal evolution facilitates effective stimulation treatments and improves well economics.

Integrated data optimizes stimulation treatments

Borehole-based microseismic fracture monitoring involves accurate imaging of the geometries of sets of hydraulic fractures (natural or induced), providing a 4D view of your reservoir’s flow network. Monitoring network design, tool selection, processing, visualization, and interpretation using seismic-to-simulation software  provides this analysis directly within the geological model, fully integrated with your seismic and petrophysical data.

The StimMAP hydraulic fracture mapping service captures microseismic activity during the fracturing process. Schlumberger petrotechnical engineers collect microseismic data from sensor arrays in nearby wells, apply processing techniques to analyze complex sets of recorded acoustic waveforms, and use advanced visualization and interpretation techniques to monitor and analyze the spatial and temporal evolution of fracture networks in 4D, relative to the location of the fracturing treatment. InterACT global connectivity, collaboration, and information service enables onsite engineers to collaborate in real time with interpreters and decision makers offsite.

Stress monitoring enhances reservoir development

Microseismic monitoring also delivers information about evolving reservoir stress that can enhance reservoir development in tight gas and shale completions, fault mapping, reservoir imaging, waterflood monitoring, drilling waste disposal, and thermal recovery.

Real-Time Interpretation

Very shallow for microseismic - best info for this approach usually acquired by putting sensors in wells that are much deeper and closer to the depth where the frac is being placed.

Could these be some sort of pipeline monitoring wells? I have seen a lot of these ultra shallow wells permitted in many areas.

Well I am probably wrong on depth, I would imagine that this is a microseismic, we do not have any pipelines near us.  Where he is talking should be about a thousand feet from where the plat shows the bore to be going through.
