So, from the bottom up, we have already conducted 2 tests on the tight reservoir rock at the bottom of the well which failed to produce commercial flow rates but reconfirmed the presence of moveable oil as they had previously during from 1 MDT. Encouraging news and with some work this could produce in my opinion.

Of the other 2 tests which were conducted on the shallower Auwerwer Sandstone section we have 1,860bopd that flowed naturally without pumping and 491bopd using a Progressive Cavity Pump.

What I would have liked to know here is which interval flowed at what rate reported. Was the interval which flowed less using the pump test #3 as detailed on the presentation above or was it test #4?

In the oil industry Progressive Cavity Pumps are used to control the flow of the oil to ensure the rate of the flow is consistent and manageable. The benefit of Progressive Cavity Pumps is that it is possible to move oil along at a slower rate while applying varying rates of pressure to the oil. These type of pumps are commonly used when dealing with heavy oil (<20API) and we have produced, at Twiga-1, 37API which is certainly not heavy oil and, in my opinion, 491bopd using a Progressive Cavity Pump for 37API oil is being significantly controlled/restricted.

We have 1 more test ongoing which will also use a Progressive Cavity Pump and the operators anticipate that this test will flow over 500bopd. In my opinion Tullow are in total control of the rate this test will flow at. That already have 1,860bopd that flowed naturally without pumping and (controlled/restricted) 491bopd using a Progressive Cavity Pump.

If they want 501bopd or 1,859bopd and above from this test is their decision.

In my opinion the oil in the Auwerwer Sandstone section is very good and although pure speculation on my part this is what I think is happened.

Starting from the bottom up as I said previously, using the detail on page 11 of the latest AOI presentation in relation to today's news.

Test #1 and #2 on the deeper section -

1 test conducted without a pump around the depth oil was previously recovered from MDT which failed to produce decent quantity. Next test using a pump also failed to produce decent quantity.

Test #3 and #4 on the Auwerwer Sandstone section -

Deepest test on this section and closest to the non producing section was conducted still using the pump given the previous unproductive tests gives 491bopd controlled/restricted. The next test, shallower, is a test to see what it can do naturally without the pump and it gives a very respectable 1,860bopd.

Test #5 on the which is ongoing.

On the shallowest test to be conducted. Given that we now have 491bopd controlled/restricted with pump and 1,860bopd flowing naturally lets stick the pump (control) back on because we know we can produce over 500bopd which is what we told the market but we could also "tweak" more and if we produce more we have impressed the market but also carefully bearing in mind that the elections are coming!

I think this last test has the potential to be the best test yet at Twiga-1 and Tullow are in total control of the flow rate. Look at the shallow depths and flow rates in Uganda, look at the initial discovery depth at Ngamia-1, look at the shallow play prospects on 10BB and look at the mention of the "light rig for flow testing activities".

We are on our way!

Tullow Oil plc (“Tullow”) announces the successful completion of the flow tests at Twiga South-1 with a constrained combined rate of 2,812 bopd from three reservoir zones. Unconstrained, the combined rate has the potential to flow at around 5,200 bopd. In Uganda, the Ondyek-1 exploration well did not encounter hydrocarbons.

These results provide encouragement for the forthcoming testing program at Ngamia-1A, Block 10BB, where four zones are planned to be tested using the Weatherford 804 rig. Testing activities are expected to commence in March and complete by the end of May.

Election worries put new
Kenya oil, gas investment
on hold

Canada's Simba Energy estimates its block in northeast Kenya sits atop 1 billion barrels of oil, but it needs investors to help stump up the cash.

"I really, really want to drill in 2013. I was prepared to commit to 2D seismic but had to consider feedback from some of our potential farm-in partners," Hassan Hassan, Simba's chief operating officer said in an interview.

"We've decided to wait, but believe me it pains me to wait," he added.....
Tullow's venture partner, Africa Oil, estimates there are 23 billion barrels of oil beneath two onshore basins that extend from southern Ethiopia to the southwestern tip of Kenya.

If proven, that would make Kenya the 13th-largest holder of oil reserves in the world, above the United States. At today's oil prices the reserves would be worth $2.6 trillion, more than 60 times Kenya's 2012 gross domestic product.
