Centek Inc.’s S2 centraliser sales in the US Rockies region topped a landmark US$ 1 million for the month of April 2014. The Centek S2 centraliser has been widely adopted for shale completions, which typically involve extended reach horizontal runs as long as 18 000 - 20 000 ft, where the strength, flexibility and low friction of the S2 units have ensured good casing centralisation.
Oil-shale rich states of the Rockies
The Rockies region includes the oil-shale rich states of Colorado, New Mexico Wyoming, Utah, North Dakota, and Montana. Tough new drilling regulations implemented in the region and across the US are designed to make drilling and hydraulic fracturing safer and to ensure well integrity. These regulations set new well standards in environmental safety for drilling, cementing, completing and production.
Previously open-hole completions were often used in extended reach wells. The new regulations combined with the performance of the S2 centraliser, benefit operators by providing better run-in-hole operations and an enhanced cement bond that improves the integrity, production and overall life of the well.
Moving towards cemented completions
“Based on these results major operators are moving towards cemented completions,” commented John Costine, Regional Sales Manager Rockies and Canada at Centek Inc. “This trend is evidenced by the Rockies region demonstrating growth of 73% above Centek’s 2013 figures for the same region, while just eight months into this fiscal year.”
“Failures in well bore integrity are the principle cause of well leakage during fracking and production operations,” said Cliff Berry, Vice-President, Global Business Development at Centek Group. "A bad cement job in the region of a water aquifer can lead to water contamination and could prove very expensive for the operator. Quality centralisers come a lot cheaper. With the change to cemented completions the operators are accepting the S2 as the centraliser of choice, clearly demonstrated by our US$ 1 million April sales in the Rockies.”
Centek centralisers are manufactured in Newton Abbot, UK and Oklahoma City, US.
