(MENAFN- ProactiveInvestors - Australia) Linc Energy (ASX: LNC) has mobilised the drill rig to its Umiat oil field on Alaska's North Slope to carry out its winter drilling program.
The winter drilling program includes the drilling and testing of shallow vertical and horizontal delineation wells in the Lower Grandstand Formation, as well as drilling and testing of a deep exploration target.
Information from this program will help validate the geological model, define the extent of the reservoirs, determine oil and rock properties for input into a reservoir simulation model, determine comparative production rates for horizontal and vertical completions and gather information on deeper reservoirs.
The Kuukpik-5 rig will drill four initial wells, the Umiat DS-1 disposal well, Umiat-16, Umiat-16H and Umiat-23.
Umiat DS-1 is expected to spud on or about 22 January 2013 and will allow for the local disposal of drilling fluids and waste.
Umiat-16 will be drilled vertically into the Lower Grandstand oil sands, where cores will be recovered before it is completed and flow tested.
This will be followed by Umiat-16H, which will be drilled directionally into the same Lower Grandstand intervals being tested in Umiat-16.
The two wells will be tested side-by-side to assess the performance of the horizontal production well in contrast to the vertical producer.
Umiat-23 will target the deeper horizons below the Lower Grandstand formation where additional natural gas is expected.
Natural gas will be required for the Umiat development, as injection of cold gas into the Upper and Lower Grandstand reservoirs will be required to maintain reservoir pressure for production.
Two additional holes have been permitted â€" Umiat-18 and Umiat-19 â€" as alternative locations for placement of wells in this winter's program. One or both of these wells could be drilled if time allows.
Crude oil samples will be taken for assay and further analysis and all wells will be drilled using mineral oil-based muds.
Following the drilling program, demobilisation from the Umiat location will commence by late April
2013.
