<span style="text-decoration: underline; color: teal;"><ins cite="mailto:Buchanan,%20Franklin" datetime="2018-11-20T00:22">Multiple transverse fracture horizontal wells (MTFHWs) are considered the industry standard in many areas around the United States.<span style="mso-spacerun:yes">
</span>Despite the initial production rates far surpassing conventional wells, they decline quickly and additional measures are taken to counteract production decreases.<span style="mso-spacerun:yes">
</span>Gas injection is a popular method for enhanced oil production; usually employing a huff and puff approach. Attempts to displace oil by injecting in one well and producing in another have not shown much success, probably because propped and/or secondary
fractures connect the wells. Simulations of an idea to inject and produce alternating propped fractures in a single well showed promise, but this approach has not been implemented operationally.

for the system. Further, we will investigate maintenance, monitoring and control options. The goal will be to identify cost effective solutions consistent with the production enhancement achieved by the system.

<span style="text-decoration: underline; color: teal;"><ins cite="mailto:Buchanan,%20Franklin" datetime="2018-11-20T00:22">This thesis will describe a completion system that would enable alternating injection and production fractures in a horizontal well. To
achieve the desired injection and production points, a configuration of downhole tools will be used to isolate every other fracture and partition the horizontal well segment into two separate flow systems at two separate pressures.<span style="mso-spacerun:yes">
</span>In order to achieve this, the system will require a number of packers equal to the number of propped hydraulic fractures each equipped with more than one bore. Each packer will be set at a specified distance from a fracture and will allow flow in opposite
directions to or from alternating fractures.<span style="mso-spacerun:yes"> </span>
Oil will flow from the formation through the production tubing while injected gas will flow in the opposite direction in the injection tubing. Research is currently being done to discover products that will make this system intelligent; from tracking fluid
flow to actuating downhole sliding sleeves from surface.<span style="mso-spacerun:yes">
</span>Conveyance of the system in the well and potential benefits or drawbacks associated with running it will be described in detail.

<span style="text-decoration: underline; color: teal;"><ins cite="mailto:Buchanan,%20Franklin" datetime="2018-11-20T00:22">This system has the potential to increase the oil recovery factor by 100% or more. We anticipate that the cost of the system will be much
less than the cost of the well. As such, the incremental production will easily justify the additional completion costs.<span style="mso-spacerun:yes">
