LOL survey estimate, not that they hit this reservoir twice already I guess:
Cumulative production to 30th September 2016 is estimated to be 0.35 MMstb. The well TLP-101ST
completed in the R2 reservoir was producing 38 bbl/d dry oil at the end of September 2016. The bottom
hole flowing pressure has risen gradually from a low of 385 psi at the beginning of 2015, to 413 psi at the
end of September 2016. The producing GOR is a little variable but is in the region of 2,800 scf/stb. The
initial reported reservoir pressure was 1,892 psi. There is no reported water production. All the produced
gas is flared.
Production commenced in January 2007 at an initial rate of over 900 stb/d. There followed a marked decline
in both rate and bottom hole flowing pressure. This was accompanied by a variable, but generally increasing
producing GOR (Figure 3.4). During 2010 and 2011 the well appears to have been on cyclic production. A
velocity string was installed in the well in late 2011. Since then the well has been on continuous production
with a gradual decline in oil rate and a steady rise in the producing GOR. Over the past 4 years the measured
bottom hole flowing pressure has remained fairly stable in the region of 400 psi. This may be due to a
number of factors such as secondary gas cap expansion, communication with neighbouring fault blocks or
aquifer influx.
