CALGARY, June 19 /CNW Telbec/ - Calvalley Petroleum Inc., (TSX: CVI.A) -
Calvalley Petroleum Inc. (the "Company" or "Calvalley"), an international oil
and gas exploration and production company based in Calgary, Alberta, is
pleased to provide the following update regarding its operations on Block 9 in
the Republic of Yemen. Calvalley owns a 50% gross working interest and is the
operator of Block 9 under a production sharing agreement with the Government
of Yemen. Calvalley holds 2,234 sq km of land area in the prolific
Sayun-Masila basin, of which only a relatively small area has been explored to
Crude oil production from Block 9 is exported under a long term sales
agreement at prices comparable to Brent crude oil reference prices. Since
starting commercial production from Block 9 in late 2005, Calvalley has been
actively engaged in major facility and pipeline construction projects that
will increase Calvalley's production capacity. Calvalley expects to
significantly increase its current crude oil production volumes as completion
of the infrastructure projects removes existing production constraints. In
anticipation of the additional processing and pipeline capacity, Calvalley
plans to continue increasing its exploration and development program.
- Gross daily production from Block 9 averaged 5,271 bopd during April
and 4,984 bopd during May. During the quarter, production volumes were
limited by the capacity of the early production facility. In addtition,
several wells were temporarily shut-in to accommodate (i) the ongoing
testing and completion program, (ii) construction activity at the
central production facility, and (iii) drilling of multilateral legs on
three of the Hiswah wells.
- Production is currently being taken from six to eight wells in the
Hiswah field and does not include nine shut-in wells in the Hiswah
field and eight shut-in wells in the Al Roidhat field. In total,
Calvalley has twenty horizontal wells in the Hiswah field and eight
vertical wells in the Al Roidhat field. All of the Hiswah wells are
tied into the central production facility at Hiswah, which Calvalley
expects to commission during the third quarter of 2007.
- Calvalley plans to begin production from Al Roidhat during the fourth
quarter of 2007, after relocating components of the early production
facility from Hiswah. Heavier oil from Al Roidhat will be processed at
Hiswah and blended with lighter crude oil production within the
specifications for Marib Light crude oil.
- Currently, Calvalley has two drilling rigs and two service rigs
operating on the Block 9. Since April 1, Rig No.1 has successfully
drilled two additional vertical development wells in the Al Roidhat
field and drilled an appraisal well at Al Hedba, the results of which
are currently being evaluated. Calvalley now has eight wells completed
and equipped in the Al Roidhat field.
- Based on the ongoing interpretation of seismic data acquired during
late 2006, Calvalley intends to dedicate Rig No.2 for exploration
drilling during the remainder of 2007. Rig No.1 will continue to focus
on development and appraisal drilling on existing fields.
- Calvalley intends to seek approval from Yemeni authorities to mobilize
a third drilling rig to provide capacity for an expanded exploration
and development drilling program in 2008. By increasing the number of
producing wells in existing and new fields, Calvalley intends to
significantly increase production volumes once its central production
facility and sales pipeline are fully operational in 2008.
Reservoir Simulation and Testing
- During the first half of 2007, Calvalley has undertaken a comprehensive
program for testing existing wells in the Hiswah field to identify
opportunities to enhance the productivity of these wells. Test results
for most of these wells were in line with the Company's expectations.
On the lower-producing wells, Calvalley has taken measures to increase
production rates through (i) remedial workovers, (ii) acid stimulation,
and (iii) drilling of multilateral legs.
- Calvalley has successfully improved the productivity of several wells
by drilling multilateral legs. The productivity of Hiswah 9 has more
than doubled since two multilateral legs were drilled while Hiswah 13
test results show a marked increase in productivity after one
multilateral leg was drilled. Drilling at Hiswah 17 was recently
completed and test results are not available at this time.
- With two service rigs under contract, Calvalley has carried out seven
well completions and workovers during 2007 on existing wells in the
Hiswah, Al Roidhat and Auqban fields. In particular, the productivity
improvement resulting from acid stimulation of the Hiswah 14 and
Hiswah 18 wells exceeded the Company's expectations. Based on those
results, Calvalley plans to acidize all of the Hiswah wells once the
reservoir simulation and testing program has been completed.
- An independent third party engineering firm has been engaged to develop
reservoir simulation models to gain a better understanding of best
practices for long term production within the Hiswah field and to
evaluate the potential for secondary recovery techniques such as water
injection and gas injection in order to optimize the ultimate oil
recovery factor over the life of the field.
- Calvalley continues to make progress toward commissioning of its
central production facility at Hiswah in July 2007. The scheduled
completion date has been deferred several weeks, primarily due to
logistical delays for construction materials and a shortage of
- The initial capacity of the central production facility will be
30,000 bopd, allowing Calvalley to increase gross oil production to
10,000 bopd from the current capacity of the early production facility.
Calvalley intends to seek regulatory approval to increase its trucking
capacity beyond 10,000 bopd until the sales pipeline is operational.
When completed, the second phase of the central production facility and
the sales pipeline will further increase Calvalley's crude oil
processing and shipping capacity.
- During May, Calvalley completed several milestones toward gaining
government approvals for tendering of major contracts for the sales
pipeline project. Tenders have now been received for the engineering
and material supply contracts, which will be awarded as soon as
regulatory approvals are received.
- Since the overall pipeline tendering process has taken longer than
previously expected, Calvalley now anticipates that the sales pipeline
will be operational during the first quarter of 2008. Once all
government approvals are in place and contracts have been awarded,
construction activity is expected to proceed in a timely manner in
accordance with schedules prescribed in the contracts.
- Processing of seismic data acquired during late 2006, together with
reprocessing of older seismic data, is now substantially completed and
the geological interpretation of this data is well underway. The 2006
seismic program targeted significant high impact exploration leads and
prospects in the central region within Block 9. The objective of this
program is to better define the geological structures within the leads
and prospects and to identify high priority exploration targets to be
drilled during 2007 and 2008.
- With a second drilling rig now under contract, Calvalley plans to drill
as many as five exploration targets during the remainder of 2007.
- In early June, Calvalley started the acquisition of more than 300 km of
seismic data in the northern plateau region of Block 9. Calvalley
expects that the acquisition and processing of this data will be
completed by the end of 2007.
