RE: Apex Spectral - ADF® DHI Dispersion Imaging Offshore Guyana
To whom it may concern,
Over the past year and a half Apex Spectral Technology has performed a series of
projects for us using both 2D and 3D seismic data offshore Guyana Deepwater. JHI holds a 40%
working interest in the Canje Block which is adjacent and immediately down slope from what is
now recognized as the prolific Stabroek Block in the Guyana basin. Exxon has now announced
over 2 billion barrels of reserves in Stabroek and is moving quickly to develop Liza and several
other discoveries into production by 2020.
Following the Exxon Liza discovery in 2015, we tested the ADF® process on a single 2D
seismic line that directly ties the well. Although the Apex dispersion imaging technology only
uses seismic data as input (i.e. well logs are not used), the ADF® DHI process impressively
imaged the Liza discovery which was corroborated by the AVO analysis of this same data.
Subsequently in 2016, Exxon drilled a second and separate AVO anomaly known as the Skipjack
well testing a new trend approximately 30 km west of Liza. This attempt resulted in a dry hole
with nominal hydrocarbon saturation. After the location and result of the Skipjack well was
known, we followed with ADF® processing on the single 2D line that ties that well.
Interestingly, the ADF® mapped no dispersion anomaly at the well location and in the sense of a
post mortem, clearly predicted a dry hole. Next, to get ahead of the drill bit and convince
ourselves of our ability to make a pre-drill prediction, three months before Turbot spud, we had
Apex process a 2D line that comes nearest to the location we thought Exxon would drill as their
Turbot prospect. While the line does not directly tie the well, we mapped several large ADF®
dispersion anomalies that easily could have tied into the well location. Impressively, the ADF®
DHI results correctly indicated the Turbot well would be a major discovery which was
announced by Exxon in November 2017. Turbot is currently scheduled for additional appraisal
in Q-1 of 2018.
In addition to the 2D seismic projects over these recent wells in the adjacent Exxon
Stabroek block, Apex has now completed ADF® processing covering our entire 6,021 Km2 Canje
Block 3D. In the now proven and prolific Upper Cretaceous/Maastrichtian play, calibrated AVO
