Regal Spuds 'New Generation' Wells in Ukraine
Regal Petroleum has provided the following update on its operations in Ukraine.
- Ukrainian well SV-58 spudded late yesterday using the second of Regal's brand-new, American-built top drive drilling rigs contracted from Saipem. Excellent progress continues on well MEX-106 that has reached 2,600 m on its way to a planned maximum depth of 6,200 m.
- MEX-106 and SV-58 are each expected to take approximately six months to complete, which is half the time typically experienced in Ukraine to drill similar wells with regionally available rigs.
- Production expected to be sustained at approximately 1,500 boepd by spring of 2009 on completion of the current well intervention work program.
- A further significant increase in production is expected on completion of the new development wells, MEX-106 and SV-58.
- Regal's gas sales price was increased with effect from January 2009 by over $US 50 to $US 242 per thousand cubic metres, representing a 26% increase from December 2008.
- Finally the Company is pleased to announce that it has executed a mandate outlining indicative terms and conditions for the prospective provision of a loan facility for up to $US100 million by Macquarie Bank Limited ("Macquarie"). Regal's current cash reserves are $US 88 million.
David J Greer, CEO of Regal, commented, "We are delighted to be spudding the second of our new generation wells targeted at increasing our Ukrainian production and reserves and are especially pleased with the excellent progress that the first rig has made on drilling casing MEX-106."
"We are also very pleased to be making good progress on securing a loan facility with Macquarie with the intention of strengthening Regal's financial position and providing the funds to implement the Company's development strategy. We look forward to working together with Macquarie to conclude this facility in the very near future and a further announcement will be made in due course."
Following the successful importation and mobilization of two brand-new, American-built top drive drilling rigs contracted from Saipem, Regal has commenced drilling a series of "new generation" wells. These wells are intended to establish additional production from the proven Visean formation reservoirs ("B-sand Production Interval") and to appraise and develop the deeper Tournaisian formation reservoirs ("T-sands") which are anticipated to contain dry gas.
MEX-106 was spudded on January 11, 2009 in the Mekhediviska Golotvshinska (MEX-GOL) field, and has reached the planned section depth of 2,600 m for the 13.3/8" casing. The well has been logged in readiness to run and cement the casing. A total of four drill bits were used to reach this casing point as compared to a previous typical requirement of ten using the older generation of rigs. By comparison to the MEX-103 well, the performance of this "new generation" well represents an improvement of eight days over the time taken to drill to the same depth using the older generation rigs. As the new drilling crews become fully trained and familiar with this new generation of equipment, the Company expects overall drilling time and performance to improve further on future wells, particularly in the deeper hole sections.
The next phase of drilling will comprise approximately 2,150 m of 12.1/4" diameter hole which will be cased before drilling into the B-sand Production Interval. The main production objective is condensate-rich gas from the B-sand sequence commencing at a depth of 4,850 m. Drilling will then continue with a 6" hole to allow penetration of the T-sands at approximately 5,700 m, before reaching a planned maximum depth of 6,200 m.
Regal spudded its second "new generation" well, SV-58, on February 26, 2009 in its Svyrydivske (SV) gas and condensate field adjacent to the MEX-GOL field. SV-58 is planned to increase production from the known reserves of gas and condensate in the B-sand reservoirs, and is also planned to drill deeper into the T-sands to appraise and develop earlier gas discoveries at this level.
The Company currently expects that the two wells, MEX-106 and SV-58, will each take approximately six months to complete, which is around half the time usually taken to drill similar wells in this basin using regionally available rigs.
As drilling progresses, a subsurface model based on 3D seismic acquired during 2007 and 2008, which has been tied into data from the existing production wells drilled on the MEX-GOL and SV licenses, will be further refined to include data from MEX-106 and SV-58, with the aim of delineating a material increase in the Company's reserve base. The Company intends to commission a new competent person's report in Q3 2009.
Production rose from a September 2008 average of 75,586 m3/d gas plus 10 m3/d condensate (507 boepd) to a peak over 2,000 boepd in November 2008, before being scaled back to allow for the well intervention work and production management activity as described below. The current sustained production rate is 148,098 m3/d gas plus 45.3 m3/d condensate (1,156 boepd). The Company expects that production will increase to around 200,000 m3/d gas plus 55 m3/d condensate (approximately 1,520 boepd) by April 2009 on completion of the well intervention work. A significant increase in production is also expected on completion of the new development wells, MEX-106 and SV-58, later in the year on completion of the drilling operations described above.
- GOL-1 Work-over -- the operation to access the remaining reserves in this well was completed successfully. The well is currently closed in with a tubing head pressure of approximately 200 bar and is being prepared to be brought into full production in mid March 2009 at an expected rate approximately 25,000 m3/d and 5 m3/d condensate (178 boepd).
- MEX-102 Work-over -- as reported previously, MEX-102 flowed gas at approximately 200,000 m3/day under test. However, these high flow rates have been reduced by mechanically choking back the well in order to maximise recovery of reserves, optimise well economics and prevent condensate banking.
- MEX-103 Well -- gas flow from this well has been insignificant to date because of damage caused to the reservoir as a result of historical drilling practices which allowed a large column of heavyweight mud sufficient time to penetrate the reservoir and cause impairment. Operations are being prepared with the objective of chemical removal of the drilling induced damage, after which sustained flow rates of approximately 30,000 m3/d gas and 5 m3/d condensate (207 boepd) are anticipated.
- Regal has now implemented a casing design for the "new generation" wells which allows the target reservoirs to be drilled more quickly, with lower mud weights. The Company envisages that these modern drilling practices, made possible by the use of new rigs, will significantly reduce the risk of such formation damage recurring. This was a key consideration in the Company's decision to discontinue sole reliance on regionally available drilling and completion equipment.
