Operations Update and Equity Dealings
June 30, 2008
Sefton Resources, the AIM listed oil and gas production company with assets in
California and Kansas, announces an update through its wholly owned subsidiary
TEG Oil and Gas Inc. (“TEG”) regarding the Tapia 2008 Q1 Drilling and Pilot
Steam Programme, and equity transactions involving two directors and two loan
note holders.
OPERATIONS UPDATE
Tapia Field - Cyclic Steaming Pilot Programme
The second well in the steam pilot, Yule #10, will be returned to production
July 1, 2008, following a successful three week steam soak cycle. The first
well, Yule #7 is producing at elevated temperatures 20˚ above that of untreated
wells after two months of production, indicating good heat retention of the
steam energy in the surrounding reservoir. Production on the Yule lease has been
relatively steady despite having the Yule #10 off-line during its steam-soak
period. This is mainly due to the increased productive rate of the earlier
steaming of Yule #7.
Tapia Q1 2008 Wells
TEG is in the process of evaluating the production and reservoir information
from the three Snow lease wells. The wells continue to produce with good oil
cuts. The wells are currently being considered as the next cyclic steam
candidates, given their proximity to the lease gas source well, Snow #1. TEG
will continue with implementing different pump arrangements to maximize the
productive rates from these wells. The installation of a larger pump in the
Lackie #A-4 well has increased the production from the well by 30% to 35% based
on daily metered well tests.

Water Production Normal in Oilfield Operations
In response to some shareholders enquires regarding water production in Tapia
oilfield operations Harry Barnum, managing director of TEG Oil & Gas comments:
‘Water naturally occurs in virtually all oil reservoirs in varying percentages
and thus is produced along with crude oil in the normal production stream from
any given oil well. The exception to this may be new wells that produce from a new oil reservoir. Over the life of a well (and later in the productive
life of an oil reservoir), the percentage of water gradually increases. The
Tapia field has been producing oil (and water) for over 50 years and has a
future productive life of an additional 40 years based on the most recent
independent engineering reserve report conducted on the field. The average water
cut (2007 annual data) for California District 2 oilfields (44 oilfields in the
vicinity of Tapia) is 86%. Tapia produces very near to that average at
approximately 90% and thus, is typical for the region. TEG has recently upgraded
the water handling facilities at Tapia as reported earlier, in anticipation of
new wells and steaming operations and manages the oil as part of the operation.
All produced water is separated from the crude oil at the Tapia production
facilities and is re-injected into the subsurface. This aids in maintaining
subsurface pressures and sustains well productive rates’.

EuEureka Canyon Field - Well Work
TEG has completed the clean outs and pump changes this week for wells in the
Eureka Canyon Field. This is part of the normal cycle of well maintenance for
this field. All wells capable of oil production are now returned to production.
The periodic well clean outs remove silt and very fine sand that collects in the
well over time and allow better exposure of the oil zones for production.
Chairman's comment
Commenting on the current situation, Chairman Jeremy Delmar-Morgan said
‘The year has started successfully. We continue to trade profitably and cash flow is running at expected levels. This is enabling us to push ahead with the steaming and drilling progammes outline in my last Chairman’s statement. None of the problems that we have encountered in the pilot steaming programme were unusual; we believe that they can be resolved and provide excellent data for the ongoing programme’.
EQUITY DEALINGS
On 24 June 2008, two note holders of the company converted notes totaling $7,000
into 47,425 shares at a conversion price of 7.5p.
In addition, also on that date, two directors, Mr. A. Ashton and Mr J.
Delmar-Morgan exercised options to subscribe for 150,000 shares each at 6p per
share, following which Mr. A. Ashton now holds 1,098,267 shares and Mr. J.
Delmar-Morgan 4,780,178 shares representing 0.9% and 4.1% of the total voting
rights respectively.
Application will be made for a total of 347,425 new common shares in Sefton
Resources to be admitted to trading on AIM and admission is expected to take
place on 4 July 2008.
