Property Descriptions
Moffat
Ranch Tri-Valley has leased approximately 5,700
acres of the Moffat Ranch Gas Field west of
Madera,
California
due to
the fact it has several untested zones that have produced on
neighboring properties.
The nine square miles of leased land,
referred to as Moffat Ranch East, is assigned to the
Tri-Valley Oil & Gas (TVOG) Opus I Drilling Program
LP. This property has two idle, accessible wells that
have productive potential if returned to production
service. It also holds another wellbore that was
previously abandoned without testing, and TVOG believes that
at least one zone is prospective and has near term plans to
re-enter the well to test this interval.
Moffat 48X: After remediating an
identified cement channel in the primary cement job that was
producing water and temporarily killing the gas production,
the well was successfully returned to production in April at
an initial rate of 300 mcf per day; the production
was ramped up slowly to avoid placing a large,
instantaneous pressure differential across the cement squeezed
water channel and allowing water to again breakthrough to the
wellbore. Production is once again in the neighborhood
of 1,000 mcf per day. All production facilities and
a sales meter run were efficiently installed and commissioned
on the 48X-7 location which served to centralize our
operations and eliminate the need to lease offset land.
Moffat 8-12: We
are continuing our attempt to restore sand-free gas production
after cleaning out the well and installing a sand screen. We anticipate
production from this well in April. A fracture stimulation may
follow pending production results.
Moffat #2:
Wellwork commenced on this well in early April to restore
production. A
fracture stimulation may follow pending production
results.
Moffat 2-7-1: The
re-entry of this abandoned wellbore will commence in
April.
Moffat 17-7:
A follow-up new drill well has been permitted and the location
has been prepared.
This well will likely be drilled in the latter stages
of 2008.

Chowchilla Ranch
Tri-Valley has approximately 6,670-acres of mineral rights, which basically covers what was the Chowchilla Ranch Gas Field in Madera and Merced Counties, California. Currently, the land position is held by production. We believe this land position to be very under developed and under exploited and we plan to begin further infill drilling the leasehold position. An additional 7,500 acres have been added to the south and west of the Chowchilla Ranch.

Sunrise
In 2000, Tri-Valley discovered
an exceptional amount of natural gas in the McClure Shale zone at 5,800 feet. However, the formation has low permeability and, so far, we have not been able to achieve commercial rates of production to obtain the bonanza benefit. After exploring the various methods that the industry has to offer with no success, Tri-Valley has engaged a major worldwide scientific research organization to help solve the problem. Tri-Valley believes the Sunrise acreage covers 3.3 trillion cubic feet of contained gas, in a formation which has ten times more per acre foot than the prolific Barnett Shale play in Texas that is now considered the nation’s hottest gas play. Once the right recovery method is identified to stimulate commercial production, a portion of the enormous amount of gas in place can be obtained.

Rio Vista
This project in northern
California consists of five wells producing approximately
400,000 cubic feet of gas per day from two separate leases. To
date, the Hanson Lease has produced over 30 billion
cubic feet of gas from this field.
Tri-Valley has
finalized a comprehensive field review to boost gas production
in the area via remedial wellwork on existing wells and
facility modifications, which may include a few new technology
applications in this field, such as plunger lift, low-cost
solids control techniques, expandable tubulars, and compressor
optimization. A workover
was recently cpmpleted on Hanson #2, including a wellbore
cleanout, replacement of the aged 1.90" tubing, and installation
of an inner liner to control sand production.
The well is currently back online at higher gas
rates than the 4 Mcfd produced prior to the
workover.

Bethel Island
This project in northern California consists of two wells producing approximately 60,000 cubic feet of gas per day. To date, Tri-Valley has produced over 20 billion cubic feet of gas from this project. A third well is being contemplated in this once prolific producing area. Presently, Tri-Valley is waiting for the results of a 3-D seismic program being undertaken by another operator to determine whether or not Tri-Valley commits to drilling a 3rd well.
