CALGARY, AB, Feb. 8, 2023 /CNW/ - Criterium Energy Ltd. ("Criterium") (TSXV: CEQ), an independent upstream energy development and production company focused in Southeast Asia, is pleased to announce that an independent assessment of the Company's Contingent Resources (the "Resource Report") in the Lengo gas field located in the Bulu Production Sharing Contract ("PSC") area in Indonesia has been completed by Netherland, Sewell & Associates, Inc. ("NSAI").


  • Significant Gas Resource: The estimated gross un-risked 2C recoverable gas resource in the Lengo gas field is 359 bcf, 134 bcf net to Criterium.[i]

  • Optimizing development plan: Criterium and its JV Partners are addressing select elements of the approved development plan to accelerate first gas and reduce upfront capital costs.

  • Updating economic case in Q2 2023: Criterium anticipates an updated economic case in Q2 2023 upon which the Lengo resource category may be upgraded from 'Development on Hold' to 'Development Pending'.

  • Identified and manageable contingencies: The Lengo field resource contingencies are: a signed Gas Sales Agreement (GSA), secured financing, and an approved final investment decision (FID).

  • Progressing towards a GSA in Q4 2023: The Bulu PSC JV Partners have signed a Heads of Agreement (HOA) in August 2022 with a credible gas offtaker and are now progressing to a formal GSA.  It is anticipated the GSA will be signed in Q4 2023.

  • Planned FID in 2024: Criterium anticipates FID for the Lengo development in Q2 2024.

The Resource Report is one of many key activities that Criterium has advanced since acquiring AWE(Asia) Ltd. and a 42.5% participating interest in the Bulu PSC in December 2022. These activities have confirmed the Lengo gas field is a large-scale gas resource with strong development potential.

Robin Auld, President and CEO, commented, "NSAI's independent assessment of the Lengo gas discovery confirms the significant gas resource and value contained in the Bulu PSC, which we are eager to realize with our JV partners.  Criterium's priority is to develop the Lengo gas field rapidly and efficiently to the mutual benefit of Indonesia and Criterium shareholders."

Lengo Gas Development: Project Description

The Bulu PSC is located 65 km offshore of East Java in water depths of approximately 50 m.  The Bulu PSC contains the Lengo gas field which was discovered in 2008 by the Lengo-1 well which flow tested 12.9 MMscf/d and appraised in 2013 by the Lengo-2 well which flow tested 20.6 MMscf/d. The drilling results identified a gas-water contact consistent with indicators on 3D seismic and a high-quality carbonate reservoir with an average porosity of 26%[ii].

The reservoir is a mid to lower Miocene carbonate build-up at a depth of approximately 700 meters and consists of an upper red algal zone and lower reefal zone that are in pressure communication.   It is not uncommon for these carbonate reservoirs to produce above the 2C resource estimate.

The Plan of Development (POD) was approved in 2014 and consists of an initial 4 well development with a pipeline delivering produced gas to the Tuban area in East Java. The Lengo gas contains impurities, including 12.4% CO2 which is common in many Indonesian basins.  The CO2 will be removed to meet pipeline specifications and Criterium is exploring potential carbon sequestration options to mitigate environmental impacts.

Criterium recently met with key project stakeholders who emphasized their desire for a quick and efficient development of the Lengo gas field.  Criterium and its JV partners, are reviewing select elements of the approved plan of development to meet stakeholder requirements and optimize capital costs. As the development plan is refined Criterium will establish an updated economic case, expected in Q2 2023, when the Contingent Resources are anticipated to be upgraded from 'Development on Hold' to 'Development Pending'.

In August 2022, the Bulu PSC partners reached a key project milestone in signing the HOA with an industrial end-user in East Java.  The gas is intended to supply growing industrial demand and feed current infrastructure and/or upgrades to existing facilities.  Gas prices reflect the increased demand and dwindling supply and are anticipated to be in the range of $6.5 - $7.5/MMbtu on a long term take or pay contract.  Criterium anticipates that the Bulu PSC partners will sign a binding GSA in Q4 2023.


The key contingencies associated with the development of the Lengo gas field by Criterium and its joint venture partners are as follows;

Oil and Gas Advisories

Contingent resources disclosed in this announcement in respect of the Bulu PSC and Lengo gas field are based on an independent evaluation conducted by Netherland, Sewell & Associates, Inc. (NSAI), with an effective date of December 31, 2022.  The NSAI estimates of resources were prepared using guidelines outlined in the Canadian Oil and Gas Evaluation Handbook and in accordance with National Instrument 51-101 – Standards of Disclosure for Oil and Gas Activities. The contingent resources are estimates only and there is no guarantee that the estimated contingent resources will be recovered.

Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingencies are conditions that must be satisfied for a portion of the contingent resources to be classified as reserves that are: (a) specific to the project being evaluated; and (b) expected to be resolved within a reasonable timeframe. In the case of the contingent resources estimated in the Contingent Resource Report, contingencies include signing of a binding gas sales agreement and securing financing and a final investment decision. Confirmation of intent to proceed with remaining capital expenditures within a reasonable timeframe is a requirement for the assessment of reserves. Finalization of a development plan includes timing, infrastructure spending and the commitment of capital. Determination of productivity levels is generally required before the company can prepare firm development plans and commit required capital for the development of the contingent resources. There is uncertainty that it will be commercially viable to produce any portion of the contingent resources.

The project maturity subclasses include development pending, development on hold, development unclarified and development not viable. All the contingent resources disclosed in this announcement are classified as development on hold. To be classified as contingent resources development on hold the following conditions must be met, (1) resources must have been discovered and evaluated through appropriate means such as drilling or tested, (2) the reservoir must have attributes that indicate potential for commercial production, (3) the development plan for the resources must have been postponed for specific reasons, and (4) the postponement of development must not be considered permanent and the resources must be expected to be produced in future years if the contingencies can be overcome.

Any references in this presentation to initial production rates are useful in confirming the presence of hydrocarbons, however, such rates are not determinative of the rates at which such wells will continue production and decline thereafter. Management of Criterium believes the information may be relevant to help determine the expected results that Criterium may achieve within oil and gas interests and such information has been presented to help demonstrate the basis for Criterium's business plans and strategies with respect to the Bulu PSC. There is no certainty that the results of the analogous information or inferred thereby will be achieved by Criterium and such information should not be construed as an estimate of future production levels, reserves or the actual characteristics and quality of Criterium's assets.

Any references in this press release to initial production rates are useful in confirming the presence of hydrocarbons, however, such rates are not determinative of the rates at which such wells will continue production and decline thereafter. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production for Criterium.

BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf: 1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. As the value ratio between natural gas and crude oil based on the current prices of natural gas and crude oil is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.
