RANGE RESOURCES LTD: Guatemala Update
13 February 2013
The Manager Company Announcements Australian Securities Exchange Limited Level 6, 20 Bridge Street Sydney NSW 2000
Range Resources Limited ("Range" or the "Company") is pleased to announce the following update with respect to its recent investment in Citation Resources Limited ("Citation") - 19.9% interest in Citation and 10% at project level - regarding the Atzam #4 Well update released by Citation (ASX:CTR) today:
- Testing continuing on Lower C17/Upper C18 carbonate sections - perforated zones cleaning up with increasing recoveries of oil;
- High quality oil (37.0° API) recovered during testing operations;
- Estimated flow rates of 300-400 bbl/day with an 85-90% oil cut from Lower C17/Upper C18 carbonates with an operational submersible pump, based on results to date;
- Upper C18 carbonates displayed impressive log results with permeability averaging 300 md and porosity averaging 17% - Rubelsanto Field (+30mmbbl produced) is 100md and 3-6% porosity; and
- Significant moveable oil identified in electric logs over C13 and C14 carbonate sections still untested- remain behind pipe above the current perforated Lower C17/Upper C18 sections.
Flow testing operations on the perforated Lower C17/Upper C18 carbonate sections in the Atzam #4 well are continuing, with encouraging results from the well having been received over the past two weeks. Latin American Resources Ltd, Operator of the Atzam Oil Project in Guatemala, has continued swabbing the well to recover the drilling and perforation fluids and establish the commercial potential of the perforated Lower C17/Upper C18 carbonates.
The Operator is now arranging to use an Electrical Submersible Pump ("ESP") to help fast track the finalisation of the clean-up operations and establish the commercial potential of these perforated zones. The Operator estimates that, with an ESP operational and based on the results to date from the perforated Lower C17/Upper C18 carbonates, the potential flow rate will be approximately 300-400 bbl/ day with an 85-90% oil cut. It is estimated that approximately 50% of the total drilling and perforation fluids used in the operations have now been recovered.
The ESP is currently being sourced from the United States and the Operator expects that it should be landed on site and operational in two to three weeks.
The recovery of high quality (37.0° API) oil from recent swabbing of the perforated Upper C18 sections, with continued pressure build ups prior to commencement of acid wash operations, is considered very encouraging by the Operator for the potential of this section. Due to the heavy muds used whilst drilling (10.5 lb/gallon) and high permeability of these carbonates, there were significant mud losses into the Upper C18 section whilst drilling, which required the acid wash to establish a clear oil cut and flow rates from these zones.
Testing Highly Prospective C13 and C14 Carbonates in Atzam #4
The Atzam #4 well produced very encouraging, and unexpectedly strong, oil shows during the drilling of the well through the C13 and C14 carbonates, which was complemented by higher than expected permeability and porosity results from the electric logs. This has established these reservoir sections, the main producing zones in the nearby Rubelsanto Field, as the most likely appraisal targets to be tested in the upcoming Atzam #5 appraisal well if they are not tested in the current Atzam #4 well.
Both Latin American Resources and Schlumberger are highly encouraged by the logging results seen in the C13 and 14 carbonates and their potential to be a new commercially productive zone in the Atzam Field to the primary C18 and C19 carbonates sections.
The Rubelsanto Field has produced over 30 mmbbl to date from eight wells and is located only 17km to the north east of the Atzam Field, along a structural fault offset.
Atzam and Tortugas Fields
The primary producing formations on the Atzam structure are the C18 through C19 formations. The Atzam #2 well had initial flow rates of 1,200 bbl/day of 34°API oil which led to new well designs for the Atzam #4 well. The second well, Atzam #5, will spud following completion of a successful flow testing program on the Atzam #4 well.
Recent mapping of the Atzam structure using existing data from previous operators (Basic, Hispanoil) and MEM, and incorporating reservoir data acquired since production initiated in December 2007, indicate the possibility of a structure of comparable size and orientation to that of the existing Rubelsanto field in Guatemala. To date, the Rubelsanto field has produced +30 mmbbl of oil since its discovery in 1976. The field currently continues to produce +1,000 bbl/day, 36 years after its discovery.
In addition to the Atzam structures on Block 1-2005, the Tortugas structure is a suspended oil field. Originally 17 wells on Tortugas salt dome were drilled by Monsanto looking for sulphur. One well (T9B) had an oil blowout at approx. 1,500 ft. and most others had oil shows in multiple zones.
The Atzam and Tortugas Fields have had previous exploration and development programs with old 2D seismic and previous production wells.

Range Resources Limited is a dual listed (ASX:RRS; AIM:RRL) oil & gas exploration company with oil & gas interests in the frontier state of Puntland, Somalia, the Republic of Georgia, Texas, USA, Trinidad and Colombia.
- In Trinidad Range holds a 100% interest in holding companies with three onshore production licenses and fully operational drilling subsidiary. Independently assessed Proved (P1) reserves in place of 17.5 MMbls with 25.2 MMbls of proved, probable and possible (3P) reserves and an additional 81 MMbls of unrisked best estimate prospective resources.
- In the Republic of Georgia, Range holds a 40% farm-in interest in onshore blocks VIa and VIb, covering approx. 7,000sq.km. Range completed a 410km 2D seismic program with independent consultants RPS Energy identifying 68 potential structures containing an estimated 2 billion barrels of undiscovered oil-in-place (on a mean 100% basis) with the first (Mukhiani-1) exploration well having spudded in July in 2011. The Company is focussing on a revised development strategy that will focus on low-cost, shallow appraisal drilling of the contingent resources around the Tkibuli-Shaori ("Tkibuli") coal deposit, which straddles the central sections of the Company's two blocks.
- In Puntland, Range holds a 20% working interest in two licenses encompassing the highly prospective Dharoor and Nugaal valleys. The operator and 60% interest holder, Horn Petroleum Corp. (TSXV:HRN) has completed two exploration wells and will continue with a further seismic and well program over the next 12-18 months.
- Range holds a 25% interest in the initial Smith #1 well and a 20% interest in further wells on the North Chapman Ranch project, Texas. The project area encompasses approximately 1,680 acres in one of the most prolific oil and gas producing trends in the State of Texas. Independently assessed 3P reserves in place (on a 100% basis) of 228 Bcf of natural gas, 18 mmbbls of oil and 17 mmbbls of natural gas liquids.
- Range holds a 21.75% interest in the East Texas Cotton Valley Prospect in Red River County, Texas, USA, where the prospect's project area encompasses approximately 1,570 acres encompassing a recent oil discovery. The prospect has independently assessed 3P reserves in place (on a 100% basis) of 3.3mmbbls of oil.
- Range is earning a 65% (option to move to 75%) interest in the highly prospective PUT 6 and PUT 7 licences in Putumayo Basin in Southern Colombia. The Company will undertake a 350km2 3D seismic program across the two licences and drill one well per licence, as well as looking to re-enter a previously suspended well that had a significant historical reserve estimate.
- Range has taken a strategic stake (19.9%) in Citation Resources Limited (ASX: CTR) which holds a 70% interest in Latin American Resources (LAR). LAR holds an 80-100% interest in two oil and gas development and exploration blocks in Guatemala with Canadian NI 51-101 certified proved plus probable (2P) reserves of 2.3 MMBBL (100% basis). Range also holds a 10% interest in LAR.

SPE Definitions for Proved, Probable, Possible Reserves and Prospective Resources
Proved Reserves are those quantities of petroleum, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations.
Probable Reserves are those additional Reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than Proved Reserves but more certain to be recovered than Possible Reserves.
Possible Reserves are those additional reserves which analysis of geoscience and engineering data indicate are less likely to be recoverable than Probable Reserves.
1P refers to Proved Reserves, 2P refers to Proved plus Probable Reserves and 3P refers to Proved plus Probable plus Possible Reserves.
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.
Contingent Resources are those quantities of hydrocarbons which are estimated, on a given date, to be potentially recoverable from known accumulations, but which are not currently considered to be commercially recoverable.
Undiscovered Oil-In-Place is that quantity of oil which is estimated, on a given date, to be contained in accumulations yet to be discovered. The estimated potentially recoverable portion of such accumulations is classified as Prospective Resources, as defined above.
