Solimar Doubles Stake in Paloma West Project

- Solimar Doubles Stake in Paloma West Project

Thursday, July 14, 2011
Solimar Energy Ltd.

Solimar has confirmed terms to increase its working interest to 25% (doubling the original 12.5%) in the Paloma West project and is soon to be participating in an appraisal well on the project.

The Paloma Deep -1 appraisal well will be drilled using Nabors Rig #710 which is expected onsite at the end of July supporting commencement of drilling in early August.

The Paloma West project is operated by Neon Energy and covers some 1400 acres all within the structural closure of the Paloma oil and gas field which has produced some 61 million barrels of light oil and 432 billion cubic feet of gas (133 MMBOE) since discovery in the 1930s. The Paloma field is a large anticline structure some 12 miles long by 4 miles wide.

The well location has been chosen using 3D seismic which was acquired after the prior development of the field. The 3D data has been used to help identify favourable reservoir trends within the field closure and all the targeted sandstone reservoirs at the well location are characterised by amplitude anomalies on the seismic. This is believed to support the presence of hydrocarbons and may also be indicative of reservoir quality.

There are seven (7) individual, stacked reservoir targets in the well commencing at approximately 10,000 feet. The well has a planned total depth of 15,500 feet and will take up to 2 months to drill. All the targeted sandstone and shale reservoirs are part of the Miocene age Monterey Formation, the famous oil source and reservoir formation in the southern San Joaquin Basin. The estimated unrisked in place hydrocarbon volumes are up to 300 million barrels OIP and based on an 11% recovery factor (equivalent to the historic recovery from the main producing reservoir of the Paloma field) the targeted recoverable resource is 33 MMBOE. Significant upside to these estimates is possible if higher recoveries are attainable.

The well will drill though a series of shallower Pliocene mostly dry gas reservoirs on the way down that are expected to be depleted by historic production. Some of these sand reservoirs are equivalent to the San Joaquin Formation gas sands that Solimar is attempting to develop at its SELH gas project further to the northwest in the basin. The shallow sands produced 23 Billion cubic feet (Bcf) of gas at Paloma.

The first reservoir to be evaluated will be in the Antelope Shale member of the Monterey which envelopes the main reservoir of the field, the Paloma or Upper Stevens Sandstone. This sand has produced 58 mmbbls and 415 Bcf and is likely to be at least partially depleted at the well location and is therefore considered a secondary target. All the Monterey Formation sandstone reservoirs including the Paloma Sandstone were originally formed as submarine fans derived from the NE and deposited into the deep water basin prevalent in the San Joaquin Basin during the Miocene. The anticlinal structure which traps the hydrocarbons was formed much later and has a
different, NW – SE orientation. So there has been varying sand quality encountered across the field which affected the historic field development, particularly for the Lower Stevens Sandstone reservoirs which were not discovered until 1973.

Only three wells have penetrated to the deeper reservoir levels in the west half of the field area (the most recent being some 26 years ago in 1985) each encountering extensive live oil and gas shows and with two wells flowing oil and gas at low rates.

Solimar believes that the 3D seismic data and modern drilling and completion technologies provide an excellent chance for a successful appraisal of the sandstone reservoirs in the western Paloma oil field. Unlike most of the original field wells that were drilled using water based muds that can react with clays in the reservoir reducing permeability (or ability to flow), the Paloma Deep - 1 will be drilled with a synthetic oil based mud to reduce drill time and minimise formation damage.

With the exception of one old vertical well recompleted for production in the Antelope Shale in 1993, the fractured oil shale potential of the acreage remains untapped. In the context of the escalating production and re development of equivalent rocks in other fields in the area, the fractured oil shales present an exciting opportunity for the new joint venture.

Solimar is increasing its interest via a farmin with Neon. The increased position in the project will be subject only to any consents to assignment of the interests that may be required by the underlying lessors and to completion of Solimar's previously announced private placement to raise A$7 million which will be processed at an EGM on July 29.

The dry hole cost of the Paloma Deep -1 is estimated at US $4.9 million. Solimar will be funding its share from cash reserves and the proceeds of the placement.

Commenting on the drill program Solimar CEO John Begg said, "It is very pleasing to be announcing another step up in the scale of the Company's assets in the San Joaquin Basin focus area. The Paloma West project perfectly illustrates Solimar's strategy of acquiring
material interests in oil prone assets that have targets in both conventional and unconventional reservoirs. Further, where hydrocarbons have already been discovered. Solimar has the opportunity to be part of the first joint venture to apply modern, off the shelf technologies to evaluate and exploit the assets. The Paloma Deep -1 is an ambitious drill program designed to evaluate a series of targets within part of a known field where the reservoirs have not been adequately tested by the historic drilling. The project provides an exciting opening to a virtually continuous 12 month program of drilling and production testing on the Company's core projects which is well illustrated in the activity schedule accompanying this release. Each of these projects represent stand - alone, technically independent opportunities for growth."

BG Doubles Santos Basin Net Potential

- BG Doubles Santos Basin Net Potential

Thursday, June 30, 2011
BG Group

BG Group on Thursday issued a material upgrade for its interests in the pre-salt Santos Basin, offshore Brazil.

Mean Total Reserves and Resources* are now estimated to amount to some 6 billion barrels of oil equivalent (boe) net to BG Group, with an upside potential of 8 billion boe net. Existing discoveries account for 96% of the mean Total Reserves and Resources.

The mean Total Reserves and Resources represents a doubling of BG Group's previous best estimate of 3 billion boe prevailing at the time of the Group's February 2010 Strategy Presentation.

The aggregate range of Total Reserves and Resources net to BG Group is from 4 billion boe (P90) to 8 billion boe (P10)**.

These new estimates result from BG Group's internal analysis based on probabilistic modelling of its Santos Basin interests. The analysis used a wealth of drilling, appraisal and other data that BG Group has gained or developed in relation to those interests, including:
  • a total of 29 wells drilled in our existing discoveries; two wells drilled on Lula since November 2010 proving particularly important in delineating the flanks of the field. Other wells have demonstrated excellent connectivity in the reservoir;
  • a total of 19 drill stem tests on current discoveries;
  • the shooting and analysis of over 14,400 square kilometers of 3D seismic;
  • full analysis of a completed extended well test (EWT) on Lula Sul and early results from the Guara EWT indicating the very large hydrocarbon volumes connected to each of these wells;
  • production from the first permanent floating production, storage and offloading vessel on Lula which commenced in October 2010;
  • development plans that include enhanced recovery processes to improve ultimate recovery factors for these giant fields; and
  • cost optimization, potential debottlenecking of facilities and greater well productivity enhancing the economic viability of later phases of development.

BG Group Chief Executive Sir Frank Chapman said: "The doubling of our estimated Santos Basin mean reserves and resources is clearly significant and demonstrates the continued rapid evolution of our understanding of these enormous discoveries. Robust economics and solid progress with the fast-track development program will see gross installed production capacity rising steadily to reach more than 2.3 million boe per day by 2017. I believe this - alongside progress with major ventures in Australia, the US and across our global portfolio - will transform the scope, scale and value of BG Group."

* Total Reserves and Resources are defined by BG Group as the aggregate of proved and probable reserves plus discovered resources and risked exploration.

** The Total Reserves and Resources upgrade announced today is based upon probabilistic modelling by BG Group of its interests in the Santos Basin, in accordance with Society of Petroleum Engineers (SPE) guidelines. The data has been analyzed, interpreted and verified by BG Group and not by the Operator or other Consortium partners.

BG Group has interests in five blocks in the Santos Basin, offshore Brazil
  • BM-S-9 (30%) containing the Guara, Carioca, Abare and Iguacu discoveries and prospects.
  • BM-S- 10 (25%) containing the Parati and Macunaima discoveries and prospects.
  • BM-S-11 (25%) containing the Lula, Cernambi and Iara discoveries and prospects.
  • BM-S-50 (20%) containing prospects including Sagittario.
  • BM-S-52 (40%) containing the Corcovado discovery.

Study More Than Doubles B.C. Gas Resources Estimate

Study More Than Doubles B.C. Gas Resources Estimate

Monday, May 09, 2011
B.C. Ministry of Energy & Mines; NEB

A new joint report on the shale-gas potential of Northeastern B.C.'s Horn River Basin more than doubles a previous assessment of gas resources within the province.

The report released by the National Energy Board (NEB) and British Columbia Ministry of Energy and Mines (BC MEM) titled "Ultimate Potential for Unconventional Natural Gas in Northeastern British Columbia's Horn River Basin" is the first publicly released probability-based resource assessment of a Canadian shale basin.

The report says the ultimate potential for marketable unconventional shale gas in the Horn River Basin is 78 trillion cubic feet (Tcf), including three Tcf of discovered resources and 75 Tcf of undiscovered resources. The Horn River Basin is part of the larger Western Canada Sedimentary Basin.

"This innovative report on shale-gas resources provides Canadians with valuable information about our energy future, particularly as it relates to the Western Canada Sedimentary Basin," said Gaetan Caron, chair of the National Energy Board.

Energy and Mines Minister Rich Coleman said, "This report should provide residents of our province with a sense of optimism about the future. B.C. is recognized for its significant shale gas reservoirs as well as for having world-class regulations."

Placing the Horn River numbers in context, the NEB currently estimates that there is 197 Tcf of conventional and unconventional natural gas remaining in the WCSB -- although this number does not take into account known but as-yet-unassessed unconventional gas resources.

The estimate of total remaining conventional and unconventional natural gas in Northeast B.C available for future demand is 109 Tcf. That includes 78 Tcf of shale gas as well as 31 Tcf of remaining natural gas resources identified in a joint assessment of conventional natural gas resources in Northeast B.C. The conventional gas assessment was released by the NEB and B.C. Ministry of Energy and Mines in 2006.

According to the new report on unconventional gas resources, the medium-case estimate of 78 Tcf for Horn River shale gas is the most realistic scenario. However, the study produced a range of numbers for shale gas potential in the Horn River Basin with the low estimate being 61 Tcf and the high being 96 Tcf.


Remaining Ultimate Potential by Province (Tcf)

The NEB is an independent federal agency that regulates several parts of Canada's energy industry. Its purpose is to promote safety and security, environmental protection, and efficient energy infrastructure and markets in the Canadian public interest, within the mandate set by Parliament in the regulation of pipelines, energy development and trade.

The B.C. Ministry of Energy and Mines manages the responsible exploration and development of British Columbia's energy sector.
