Sintana Energy Announces Results of an Independent Evaluation Report of Conventional and Unconventional Resources for its VMM-37 Block in Colombia


TORONTO, Nov. 20, 2012 /CNW/ - Sintana Energy Inc. (TSX-V: SNN) ("Sintana" or the "Company") is pleased to announce the results of an independent, NI 51-101 compliant resource evaluation report (the "Report") prepared by Petrotech Engineering Ltd. ("Petrotech"). The Report titled "Evaluation Of The Interests of Sintana Energy Inc. in the VMM 37 Block in the Middle Magdalena Valley Basin Colombia" dated November 16, 2012 provides conventional and unconventional prospective resources on its 43,000 acre VMM 37 Block in Colombia.

For the conventional formation (Lisama) on the Block, in which the Company has a 100% private participation interest, Petrotech calculated a P50 best estimate effective July 31, 2012 of unrisked prospective recoverable resources of 51 million barrels of oil.

As to the unconventional zones of interest, Petrotech has assigned a P50 best estimate effective July 31, 2012 of unrisked prospective recoverable resources of 700 million barrels of oil.  As recently announced, and for the purpose of the evaluation, the Company has farmed-out a 70% participation interest in the prospective unconventional resources in the Tablazo, Salada and Galembo formations to ExxonMobil Exploration Colombia Limited who will pay 100% of the exploration costs of the first three wells to drill down to the Tablazo.  These wells will likely encounter the Lisama formation (conventional - Sintana 100%) and ExxonMobil will provide the electric logs of this section for evaluation by Sintana at no cost to the Company.  If hydrocarbons are encountered in the Lisama, the subsequent testing and development of this formation will be borne 100% by the Company.   In addition, ExxonMobil is to pay $45 million for Phase 2 (initial development phase) of the work program.  Once first production is achieved, Sintana will pay back $10 million from 50% of its proceeds.

The P50 best estimate before royalties for the Company's remaining 30% interest in the unconventional formations is a prospective recoverable resource of 210 million barrels of oil.

1) The Lisama Formation is conventional resources and the Tablazo, Salada and Galembo Formations are considered as unconventional resources.
2) Each formation is assumed to receive commerciality individually.
3) The estimated net present values disclosed do not represent fair market value.

This evaluation uses the definition of resources and follows the guidelines from the Canadian Oil and Gas Evaluation (COGE) Handbook. From geophysical and well data available at this time, three prospects have been identified in the VMM 37 Block in the Lisama, Galembo, Salada and Tablazo Formations.  The evaluation above provides the unrisked prospective resources (prospects) in the Lisama, Galembo, Salada and Tablazo Formations. The Galembo, Salada, and Tablazo resources are considered as unconventional.  The chance of discovery and the chance of development are also assessed in the report.

Sintana's CEO, Doug Manner, commented, "We are very pleased with the significant increase in our estimated prospective recoverable resources. In little more than a year, the Company has grown its asset portfolio in Colombia to a point where it has exposure to conventional and unconventional value creation opportunities in a number of highly prospective blocks. The Petrotech Report incorporates the updated information over the past year and provides further validation of the significant potential of our participation interests in the various formations underlying our VMM-37 license."

Definition of Prospective Resources

Prospective Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects.  Prospective resources have both an associated chance of discovery and a chance of development.  Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates, assuming their discovery and development, and may be sub-classified based on project maturity. Not all exploration projects will result in discoveries.  The chance that an exploration project will result in the discovery of petroleum is referred to as the "chance of discovery."  Thus, for an undiscovered accumulation, the chance of commerciality is the product of two risk components - the chance of discovery and the chance of development.

Uncertainty Categories

Estimates of resources always involve uncertainty, and the degree of uncertainty can vary widely between accumulations/projects and over the life of a project.  Consequently, estimates of resources should generally be quoted as a range according to the level of confidence associated with the estimates.  An understanding of statistical concepts and terminology is essential to understanding the level of confidence associated with resources definitions and categories.  These concepts, which apply to all categories of resources, are outlined in Sections 5.5.1 to 5.5.3 of the report.

The range of uncertainty of estimated recoverable volumes may be represented by either deterministic scenarios or by a probability distribution.  Resources should be provided as low, best and high estimates as follows:

  • Low Estimate: This is considered to be a conservative estimate of the quantity that will actually be recovered.  It is likely that the actual remaining quantities recovered will exceed the low estimate.  If probabilistic methods are used, there should be at least a 90 percent probability (P90) that the quantities actually recovered will equal or exceed the low estimate.
  • Best Estimate: This is considered to be the best estimate of the quantity that will actually be recovered.  It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate.  If probabilistic methods are used, there should be at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate.
  • High Estimate: This is considered to be an optimistic estimate of the quantity that will actually be recovered.  It is unlikely that the actual remaining quantities recovered will exceed the high estimate.  If probabilistic methods are used, there should be at least a 10 percent probability (P10) that the quantities actually recovered will equal or exceed the high estimate.

This approach to describing uncertainty may be applied to reserves, contingent resources and prospective resources.  There may be significant risk that sub-commercial and undiscovered accumulations will not achieve commercial production.  However, it is useful to consider and identify the range of potentially recoverable quantities independent of such risk. 


The Company is primarily engaged in petroleum and natural gas exploration and development activities in Colombia and Peru. The Company's exploration strategy is to acquire, explore, develop and produce superior quality assets with significant reserve potential.  The Company currently holds a 25% interest in the 175,000 acre Bayovar Block XXVII in the Sechura Basin, Peru. The Company's private participation interests in Colombia include 30% in 58,570 acres in the Talora Block and 30% in 272,021 acres in the COR-39 & COR-11 Blocks in the Upper Magdalena Basin. In the Middle Magdalena Basin, it has private participation interests of 100% in the conventional formations, and 30% in the unconventional formations, in the 43,158 acre VMM-37 Block and 25% (carried) in the 154,909 acre VMM-4 and 59,522 acre VMM-15 Blocks. In the Llanos Basin, the company has a carried 25% private participation interest in the 111,624 acre LLA-18 Block. These interests are subject to all applicable regulatory and governmental approvals, including those of Colombia's National Hydrocarbon Agency (ANH). The Company continues to evaluate a portfolio of exploration opportunities in South America.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Most of the IoT Gateway scenarios involve collecting data from machines/processing and pushing data upstream to cloud for further analytics.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
