Mississippi Lime:

Production & Produced Water Congress 2013

Iofina, specialists in the exploration and production of iodine and iodine specialty chemical derivatives, are pleased to announce the Company will be presenting at the Mississippi Lime: Production & Produced Water 2013 Conference. The conference to be held in Oklahoma City June 26th and 27th gathers together the leading production professionals operating in the Mississippi Lime. The list of speakers and participants includes many of the area's leading producers.

The Mississippi Lime has been characterized as the "New Bakken" with estimates that production can hit 500,000-boe/d mark by 2020.[1] This play is characterized by shallow, low-cost wells that deliver, making it a bargain in the North American shale scene. The Mississippi Lime has a net of 11,000,000 acres with the play's horizontal core being approximately 7,000,000 acres spread across north-central Oklahoma and south-central Kansas.[2] The largest operators in the area are Sandridge Energy, Chesapeake Energy Corporation, Range Resources Corporation and Midstates Petroleum Company, Inc.[3] The development of the Mississippi Lime had been impacted due to the quantity and expense involved in disposing of the brine water. These obstacles have been overcome and now Baker Hughes estimates there are 92 rigs actively working in the core area.[4] With the robust quantity of water and concentration of iodine, the Mississippi Lime has afforded Iofina with an enormous opportunity utilising one of the largest waste streams in North America. Iofina's proven IOsorb™ technology allows operators to reduce costs associated with the disposal of their brine stream. This allows our partners to reduce their operational expense compared to non-Iofina partners in the area.

Iofina is currently working with several of the area's largest producers and continues to expand its presence. The Company currently has two plants producing iodine, one in the Mississippi Lime and construction has commenced on IO#3. Construction of IO#4 is expected to be completed circa 30 days after IO#3.
