This material balance report covers the primary production period (Jul. 2004 — Nov. 2005), as well as the gas storage operations that have taken place since Dec. 2005. The 77-3 reservoir in the Swanson River field was in active use for all of 2016 and was an important component of total gas deliverability for the Cook Inlet. There are two active wells that are used for injection and production — SCU 42-05X and SCU 42-05Y. Hilcorp has performed material balance calculations on the 77-3 reservoir to provide assurance of continued reservoir confinement of the gas storage volumes. Supporting data is attached in numerical and graphical form for the convenience of the reader. As of January 1, 2016 the estimated reservoir pressure in the 77-3 was approximately 3,100 psia as estimated from the attached chart. Notice that eleven BHP calculations were made for the 2016 storage cycle between January and December. These were in addition to two bottom -hole SI pressures take in March and October. These data points are plotted with the historical data and they conform to the overall curve, indicating continued confinement of the storage gas.
