Process Description. Chart 4.1 in Section 4 is a block flow diagram showing the overall gas and liquid flows for Platform ▇▇▇▇▇ and LOGP. The gas which is not in solution in the oil is separated from the oil on Platform ▇▇▇▇▇. The oil produced from the Tidelands ▇▇▇▇▇ will be segregated from the oil produced from the existing Pt Ped production and metered by turbine meters and adjusted for sediments and water (hereinafter “S&W”) on Platform ▇▇▇▇▇. Gravity samples will also be taken before commingling so that each area can receive the corresponding price adjustment for the purchaser’s gravity scale. Initially, two of the test separators will be dedicated to the Tidelands ▇▇▇▇▇. One of the test separators will be used as a gross separator. Once the production exceeds the capacity of the test separator which is being used as a gross separator, excess volume will be delivered to the three phase separator dedicated to the Tidelands ▇▇▇▇▇. All Tidelands oil produced will be combined before entering a three phase separator then metered (FT-250 & FT-251) separately and adjusted for temperature and S&W (TA-250 & OWD-250) before being commingled with Pt Ped production. The Pt Ped production will also be delivered through a three phase separator. Oil produced will be combined before entering a three phase separator then metered (FT-220 & FT-221) and adjusted for temperature and S&W (TA-220 & OWD-220) before being commingled with the Tidelands production. The oil production is then discharged into the shipping tank that moves through a common pipeline which ships the oil emulsion to the onshore LOGP facility. Once the oil emulsion is onshore, the oil is separated from remaining water and any gas which also evolves from the process is recovered via the vapor recovery system. Gasoline and condensate extracted from the process stream at LOGP are metered as they leave LOGP and may be blended with the dry oil prior to entering Lease Automatic Custody Transfer unit (hereinafter “LACT”) A and/or B (meters 556 and 557 respectively). The dry oil plus these additions is metered through LACT A and/or B at LOGP prior to entering the ConocoPhillips pipeline system. Oil may also be sent to storage on a limited basis. The actual Pt. Ped and Tidelands oil production is determined by allocating the total monthly shipments from LACT A and/or B at LOGP less blended condensate (meter 2469) and blended natural gasoline (meter 2468) and adjusted for changes in inventory (plus ending inventory, minus beginning inventory as described in 1.2.C below) back to the two production areas based on the theoretical net oil volumes from Platform ▇▇▇▇▇. Once the Pt. Ped and Tidelands share of the actual oil is determined, the production will then be allocated to each well based on well test data as described below. Generally, every well is tested at least twice per month for a period of 24 hours. When a well is not in test, the fluid flows through a gross separator, one designated for Pt Ped production and one designated for Tidelands production. The individual theoretical well production is determined by multiplying the applicable well test production rate per day by the corresponding days the individual well was open to production [well test production rate x days on production = individual well theoretical production]. The total Tidelands or Pt Ped actual oil production will be prorated to the producing ▇▇▇▇▇ by multiplying the total Tidelands or Pt Ped production by the result of dividing the individual well theoretical production by sum of all theoretical well production from the corresponding area which equals the actual individual well production [total Tidelands or Pt Ped production x (individual well theoretical production / sum of all area theoretical well production) = actual individual well production].
