Frac work is the practice of injecting a well with large amounts of proppants under high pressure to break the reservoir rocks and allow hydrocarbons to flow through the open cracks in the rocks.
Good quality reservoir accompanied by excellent oil shows
The Wizard Lake Rex exploration well intersected a virtually continuous reservoir section from the casing shoe (1536 mMD) to the total depth of the well at 2773 mMD with good quality reservoir accompanied by excellent oil shows and elevated gas readings.
Due to the continuous nature of the reservoir in the horizontal section, the frac stages have been evenly spaced along the well bore at about 43 metres apart.
Each stage will emplace about 30 tonnes of proppant using a crossed linked gel to achieve high proppant concentrations at low pump rates.
The frac work is expected to be completed within two weeks and will be followed by normal clean-up flows and testing.
The Point Loma Joint Venture (PLJV) is an established producer with existing oil and gas processing facilities and pipelines into markets.
The PLJV now intends to delay the second exploration well at Wizard Lake until the testing of the Rex well has been carried out and the results evaluated.
With a positive test result, the PLJV will be looking to accelerate the development of the Rex pool by directing drilling funds towards field development work.
Whitebark managing director David Messina said: “We are very pleased by the well results.
“Not only does it appear we have a very exciting well on our hands but the drilling operation has been done on time and budget.
“We look forward to the frac work being finished so we can commence the testing program.”
“We are also encouraged by the announcement by the provincial government to temporarily reduce oil production by 8.7% (325,000bopd).
“This will remove excess supply from the market and support oil pricing. As the PLJV produces less than 10,000bopd, it is unaffected by the cuts but will enjoy the benefit of any rebound in oil pricing.”
