Intervale Capital’s Antelope buys WearSox

Antelope Oil Tool & Manufacturing Co., a portfolio company of Intervale Capital, said Monday that it has acquired WearSox. No financial terms were disclosed. Headquartered in Houston, Texas, WearSox is a maker of centralizers, stabilizers and stop collars for cementation and casing-while-drilling applications.


HOUSTON, Nov. 4, 2013 /PRNewswire/ — Antelope Oil Tool & Manufacturing Co., LLC (“Antelope”) has acquired WearSox, L.P. (“WearSox”). Founded in 2004, WearSox is a pioneer in the development of thermal spray-on casing centralizers, stop-collars and stabilizers, primarily for deep water and other highly technical oil and gas applications. WearSox’s patent-protected process is unique in the industry, allowing for shapes to be built directly onto casing or other downhole products at low temperatures, avoiding any impact to the metallurgical properties of the base material. Headquartered in Houston, Texas, WearSox has built a premium brand through its commitment to innovation and quick-turnaround service.
Antelope is a leading manufacturer of oilfield casing and cementing products for onshore and deep water applications globally. Antelope is backed by Intervale Capital (“Intervale”), a private equity firm which invests exclusively in oilfield manufacturing and service companies.
George Ribble, Antelope’s chief executive officer, will oversee the combined business. Ribble joined Antelope after having spent 16 years helping build Weatherford International into a leading player in casing hardware, most recently as Weatherford’s Global Product Line Manager of Cementation Equipment. Ribble commented, “WearSox is a unique solution for quick-turn, deep water centralization and other technically challenging applications. We are thrilled to partner with such a dynamic company and outstanding team. We look forward to bringing a range of innovative centralization products to market using the expertise of both WearSox and Antelope.”
John Gammage, WearSox’s president, commented, “The combination with Antelope makes perfect strategic sense. Antelope brings to WearSox a wealth of technical knowledge accumulated over its 52 year operating history. Antelope’s expertise and resources will allow us to better serve our customers and accelerate growth.”
“WearSox expands Antelope’s presence in close-tolerance centralization, a rapidly growing market that is critical to drilling and completing wells safely in highly technical environments, particularly in ultra-deep water. Management expects to grow WearSox by expanding its sales force and manufacturing capacity, and entering new markets overseas,” said Tuan Tran, Principal at Intervale.
Antelope and WearSox participate in the $1.5 billion casing and cementation hardware market, which has grown at a 12% compounded annual growth rate since 2005, according to Spears & Associates.
