Gas from the wellhead contains all kinds of impurities. The first step is to run it thru a seperator where liquids contained in the gas stream are removed as the wellhead pressure is lowered. At this point the stream is tested for BTU content. Generally a Btu value in excess of 1150 is too rich to be mixed with pipeline quality gas (1030 Btu), although I know of instances where gas greater than 1150 Btu was mixed with pipeline quality gas. It all depends on the volume flowing and the existence…
Gas from the wellhead contains all kinds of impurities. The first step is to run it thru a seperator where liquids contained in the gas stream are removed as the wellhead pressure is lowered. At this point the stream is tested for BTU content. Generally a Btu value in excess of 1150 is too rich to be mixed with pipeline quality gas (1030 Btu), although I know of instances where gas greater than 1150 Btu was mixed with pipeline quality gas. It all depends on the volume flowing and the existence of processing facilities downstream of the meter into the pipeline. Back to the wellhead, gas which has been thru a seperator and is less than 1150 Btu still needs to be dehydrated to remove any water vapor in the gas to less than 7 lbs per Mcf. At this point the gas is "pipeline quality" and can be injected into the pipeline at the meter. The meter is typically the point at which ownership of the gas passes from the producer/gatherer to the buyer (marketer, processor, utility, etc.). Any gas with a Btu content greater than 1,000 Btu has some amount ethane, propane etc that in many cases can be removed in processing plants downstream.<br />
<br />
The value of the gas produced is determined by its Btu content. The higher the Btu, the higher the price. Thanks pg guy.tag:gomarcellusshale.com,2014-08-05:2274639:Comment:6087202014-08-05T15:49:45.630ZJoseph-Ohiohttps://gomarcellusshale.com/profile/JosephEPowell

<p>Jeffrey, by definition they can not "run together". If you put wet gas from one well in a pipeline and dry gas from another well you will have gas that is either above 85% methane or below 85% methane. You will have either wet gas or dry gas but NOT both. It could change on a daily basis depending on production at any given well and the addition of new wells on the pipeline. Also where is your pipeline going .... for residential use? You CAN NOT send wet gas to residentail homes. Wet gas…</p>

Also where is your pipeline going .... for residential use? You CAN NOT send wet gas to residentail homes. Wet gas must be processed further. This is why people are not getting FREE gas from these wells but in lieu of payments if they have a pad on their property.<br/> Wet gas is separated at a cryo plant not at well head. Dry gas is piped to storage field or compressor station for resdential use. They do not build two pipelines from one well ... the gas is either wet or dry.

Typically gas going into storage in a depleted O&G reservoir is from pipeline supply, therefore by definition it is dry gas, i.e., gas that has been fully processed for retail sale. However, depending on the nature of the reservoir used for storage, as gas is withdrawn from storage, it sometimes requires additional treatment to re-strip liquids that have come out of the storage rocks along with the gas.

<p>I believe that would be two different questions, the answer to the original question as to whether you can run wet and dry gas in the same line is yes. And in fact prior to the boom in wet gas production, the wet Marcellus gas was mixed with dry gas in the system bringing the higher BTU wet gas down into spec.

<p>I believe that would be two different questions, the answer to the original question as to whether you can run wet and dry gas in the same line is yes. And in fact prior to the boom in wet gas production, the wet Marcellus gas was mixed with dry gas in the system bringing the higher BTU wet gas down into spec. Now that wet gas has vastly over taken dry gas production, and cryo/jt and fractionalization facilities are being built out, the ability to process the gas has increased a materially(although significant infrastructure constraints still exist) and the need to mix down the wet gas has diminished. In any event the answer tot he original question is, Yes you can mix. For instance, if the only infrastructure in the area already has dry gas in it, and there are binding contracts, then you aren't going to shut in your wells - you are going to hook into the system and sell your gas (assuming there is processing inline). See the article from the link below, there is multiple articles referring to the blending of dry and wet gas available on the internet if you are interested.</p>

<p> "If additional blending capacity is required, phase two of Williams’ solution would be to ship a high-Btu mixture on the proposed Keystone Connector pipeline to its Transco interstate pipeline, where the gas would be blended before entering the system. Economically, large-scale blending restricts the return on Marcellus NGLs to the prevailing natural gas price. However, because the cost of blending is expected to be well below the price of proposed pipeline or marine shipment alternatives, it could play a critical role over the short and intermediate terms."</p>

Thanks to each of you for your information. I have received a lot of good info from your posts. I was wanting to know if I would be going through the trauma of a second pipeline installation.
