PUBCO

PAN AMERICAN


The Florance #5 was completed as a Mesaverde-Dakota dual in September, 1965 with 4-1/2" casing and one string of 2-3/8" tubing. The Dakota produces up the tubing and the Mesaverde flows up the casing-tubing annulus. Because of the large flow area in the annulus, the Mesaverde is experiencing liquid loading problems which are restricting the production from that zone.

Enclosed are decline curves for both the Mesaverde and Dakota zones.

The bottom-hole pressure of the Dakota was measured with a pressure bomb and found to be 780 psig at 7500' after 8 days of shut-in. This Dakota pressure corrected to a datum of 5000' is 708 psig. A pressure bomb could not be run for the Mesaverde since this zone produces up the annulus. A dead weight surface pressure of 395 psig was recorded for the Mesaverde after 8 days of shut-in and the f l u i d level on the annulus was recorded at 4805'. The bottomhole pressure for the Mesaverde was then calculated to be 539 psig at a datum of 5000'. The requirement that the lower pressured zone have a pressure that is greater than 50% of the pressure of the higher pressured zone corrected to a common datum is; therefore, satisfied.

Compatibility tests were conducted using the produced Dakota water from this well and the Mesaverde water from an offset to the Florance #5. The testing indicates that no scale of precipitate problems should result from the commingling of these two zones. In addition, the salinities of the two zones are similar enough that no formation damage should occur in either zone.

The intent of commingling these two zones is to increase the total production from the well. This w i l l be accomplished by increasing the flow velocity by flowing both zones up the tubing. The cross-sectional area of the tubing is 3.13 square inches, as opposed to 11.27 square inches for the tubing and annulus. Even i f no production increase were realized, a 3.6 fold increase in average flow velocity would result from this commingling. This velocity increase w i l l enable the well to unload produced fluids and w i l l result in increased gas production from each zone. This greater production rate w i l l increase the velocity in the tubing, yielding even more liquid l i f t i n g capacity.

Based upon the decline curves and reserve estimates for these zones, I recommend that the production be allocated on a s t r i c t percentage basis with 98% assigned to the Mesaverde and 2% assigned to the Dakota.

I f you need any additional information, feel free to call me at (303) 740-4840.
