Erin Energy Announces Production Rate from the Oyo Field

Oyo-8 exceeds 7,000 barrels of oil per day

HOUSTON, May 18, 2015 - Erin Energy Corporation (“Erin Energy” or the “Company”) (NYSE
MKT:ERN) (JSE:ERN) announced today that the Oyo-8 well (“Oyo-8”) located in OML 120
offshore Nigeria has exceeded expectations and is currently producing at a stabilized rate of
7,080 barrels of oil per day. Erin Energy is the operator and has a 100% interest in the well.

Erin Energy is currently engaged in drilling and completion operations on the Oyo-7
development well and expects to achieve first oil production from the well in a few weeks.

Additionally, in preparation for the planned drilling of one of its Miocene exploration prospects
later this year, the Company has completed site survey of three of its top prospect drilling
locations. Erin Energy announced last year that it had identified, and high-graded to drill-ready
status, four Miocene exploration prospects. The four prospects have a combined 2.4 billion
barrels of recoverable P50 prospective resources.

Segun Omidele, Senior Vice-President of Exploration and Production commented: “We are
pleased with the Oyo-8 well’s performance and delighted that well parameters are stable. We
plan to continue this very cautious well management approach and expect to bring Oyo-7 on
production in a similar manner. We are advancing both our development and exploration work
offshore Nigeria and look forward to an exciting second half of 2015.”

Resource Estimates

This press release refers to prospective resources, including recoverable resources. The
Securities and Exchange Commission (“SEC”) permits oil and gas companies, in their filings
with the SEC, to disclose only “reserves,” as that term is defined under SEC rules. Prospective
resources are those quantities of petroleum estimated, as at a given date, to be potentially
recoverable from undiscovered accumulations by application of future development projects.
Prospective resources have both an associated chance of discovery and a chance of
development. Investors should not assume there will be any discovery associated with
prospective resources, or that any discovery will be economically drillable or ever be upgraded
into reserves.

developments that the Company expects, believes or anticipates will or may occur in the future
