Lime Rock Partners Announces Sale of Sensa Ltd. to Schlumberger


WESTPORT, Conn., December 5, 2001 – Lime Rock Partners, a private equity firm that provides growth capital for the energy industry, announced today that it has realized a significant gain from its investment in Sensor Highway Ltd. (Sensa), which was acquired by Schlumberger Oilfield Services.

Funds managed by Lime Rock initially invested in Sensa, a world leader in fiber optic based reservoir solutions for the oil and gas industry, in February 2000. Lime Rock made two follow-on investments for a total of $9.6 million. 3i, a leading international venture capital company, was a co-investor in Sensa.

“Our successful investment in Sensa demonstrates our focus on the most significant growth areas within the energy industry and our deep understanding of the most promising emerging technologies that are reshaping it,” said John Reynolds, Managing Director of Lime Rock and former leading energy industry analyst at Goldman Sachs & Co. “Our investment approach is to identify well-managed, high-growth energy companies like Sensa that require capital to fulfill their strategic growth plans. With the completion of this investment, Lime Rock has returned 90% of its first fund capital in less than three years.” With Lime Rock’s assistance, Sensa strengthened its competitive position in providing fiber optic downhole tools and completed two strategic acquisitions.

“Lime Rock was a valued business partner to the company,” said Glynn Williams, Chief Executive Officer of Sensa. “In addition to providing much needed growth capital, they were instrumental in helping us implement our strategy.”

Lime Rock’s gain on its Sensa investment follows its successful sale of the majority of its ownership position in IPEC Ltd., a Canadian based oilfield service concern. Funds managed by Lime Rock had invested a total of $17.7 million in IPEC for a 38% stake. In addition to the $34 million in cash proceeds received, Lime Rock retains a substantial stake in Flint Energy Services Ltd. (TSE: FES), the corporate entity that combined with IPEC. In August of this year, Lime Rock sold its half interest in a joint venture established to own and operate a harsh environment offshore drilling rig, the Noble Julie Robertson, to the operator of the joint venture, Noble Drilling Corporation (NYSE:NE) for $20 million.
