I will now turn it over to Chris Walker, our COO, to review our assets and operational performance, then Jeff Slotterback, our CFO, will review some of our key financial metrics before I conclude with a discussion around our broader strategy and future expectations.

Thanks John. As a reminder, the overwhelming majority of the Partnership’s assets are situated in the black oil window of the Eagle Ford shale in Atascosa County. We acquired the undeveloped acreage in a transaction at the end of 2014, right before the industry entered a multi-year downturn that saw oil prices fall by 70%. After closing the acquisition, we immediately deployed additional capital to develop the position by completing 10 horizontal wells that had been drilled but not completed by the seller. The combination of the timing associated with both the acquisition as well as the lack of recovery in commodity prices during the initial flush production period from the new wells has put us in the position we are in today where the company has to rely on additional drilling or acquisitions to grow andre-initiate a dividend beyond the $25 million already paid. But despite this broader market backdrop, we have remained active, drilling and completing one well in 2018 called the Skeeter4-H. The Skeeter4-H well has performedin-line with our expectations and has produced gross total 70,000 barrels of oil equivalent to date of which 93% is oil. The success of this well gives us confidence that our remaining inventory of locations will drive strong value to the partnership if we drill them. Including the contribution from the Skeeter4-H as well as the other 10 Eagle Ford horizontal wells and 2 smallnon-operated wells owned by the partnership in Oklahoma, our fiscal year 2018 and Q1 2019 production averaged 504 and 431 boe/d, respectively with roughly 80% of that being oil.
Our Eagle Ford position of approximately 2,800 contiguous net acres allows us to drill extra-long lateral length wells that yield better economics than shorter length horizontal wells. Specifically, we estimate that we have 12 undeveloped locations that can be drilled at single-well economics that range between30-50% IRRs based on today’s commodity prices. Of those 12 locations, 7 of them average 13,000 feet of lateral length. The expected capital required to drill these 7 locations is between $50 and $60 million. The average payback on these 7 wells ranges from 1.2 to 1.5 years depending on certain assumptions around the amount of capital per well, operating expenses and commodity prices. Cumulatively, we would expect these wells to generate between $50 to $60 million of contribution margin (net of the capital to drill) over the economic life of the wells.
Our operating team has drilled and/or completed 27 horizontal wells in our Eagle Ford area and an additional 150 in the broader South Texas region. As a result, we feel that our working knowledge of the Eagle Ford shale, both in close proximity to our acreage as well as in other parts of the play, is a core strength that can be used to grow the partnership, whether thru the organic drilling of our remaining inventory of undrilled locations or thru acquisitions.
With that, I will hand it off to Jeff.

Thanks Chris. I will begin by discussing our latest balance sheet, our 2019 financial outlook and our reserve metrics. As of our March 31st 2019 quarter that just recently closed, we have nearly $4 million of cash, $27 million of assets and no debt. For 2019, we expect to be roughly breakeven to slightly positive for cash flow generation and thus we expect to end the year approximately where we reside with a $4mm cash balance. These monies are earmarked for the execution of our growth strategy. While our strategic plan is not one that assumes no drilling or acquisition activity, the cash balance estimate is based on an outlook consistent with current commodity strip prices and does not include any incremental production
