Recommendations

​​










At this time, we most recommend installation of MCS production tubing in vertical gas wells with liquid loading problems, especially those just proir to implementation of artificial lift and those with no water encroachment.

Although the tensile strength of MCS production tubing will allow use in depths of over 6,000 feet, given our experience at this time, we recommend implementation in wells up to 4,000 feet and we stock 3,600-foot coils.  
Gas and water production limits are about 20 Mcf and 6 Bbls per day.  
Burst strength exceeded the 550 psi limit of available testing equipment, including the incorporation of our custom-machined injector available for the capillary injection of chemicals to prevent blockages.

Many gas wells to be plugged or abandoned could easily produce for another 5 to 10 years using MCS production tubing. This one-inch diameter MCS extrusion design, with its 5.5 mm diameter passageways,  provides maximum efficiency in the transfer of the energy of the gas phase (pressure) to that of the liquid (height).  Also, individual MCS extrusion passageways can be shut off by gluing a scew into a passageway, so they can be sequentially closed one by one with production decline... an MCS well can literally be produced down to under 1 Mcf per day with no liquid loading.  
As long as the reservoir is not being encroached with water, the available reservoir pressure should be sufficient to lift whatever original saturated liquids (vapor) that are now being produced as liquid.  Not only will the well produce revenue, but the plugging expense can be postponed indefinitely. 

Those frustrated with their plunger lift operations may also have well candidates.  If you provide specific well data (depth, average Mcf and Bbl per day, shut-in bottomhole pressure and line pressure) by email, we would be happy to provide our recommendations.

We welcome inquiries regarding custom MCS production tubing designs for other well candidates or applications.
