The Quinlan #1 was originally open hole completed in the 1st Wilcox Sandstone from 4,778′ to 4,782′ (T.D). for 334 BO in 15 hours and no water. The Simpson Dolomite from 4,742′ to 4,750′ and the Viola Limestone from 4,726′ to 4,732′ were tested several years later. Later production from the Quinlan #1 was documented producing an oil cut from 8 – 15%, (i.e. 100 barrels of total volume = 8 to 15 barrels are oil) on a daily basis from the 1st Wilcox Sandstone (Primary Objective), Viola Limestone and Simpson Dolomite (Second Objective). Finally, the Hunton Limestone formation was perforated and produced on a forty acre spacing pattern and was also perforated in the Quinlan #2. Since November 2009 when the well was purchased by Nitro Petroleum Inc., the Quinlan #1 has produced 13,946 barrels of oil from the Hunton Limestone. Several other fields in the area producing from the Hunton Limestone would alone in this wellbore produce enough oil to pay out the complete project.
The Quinlan #2 was originally drilled to the base of the Simpson Dolomite formation and completed in the Hunton Limestone. The Hunton Limestone was perforated (See Halliburton Well Log in Figure 3) from 4,594′ to 4,604′ flowing 298 BO and 272 MCFG in 12 hours, no water. In 1976, the well was deepened to the 1st Wilcox and perforated in the Viola Limestone from 4,720′ to 4,733′ and the Simpson Dolomite from 4,756′ to 4,762′. In February of 2011, the well was installed with a 70HP down-hole test submersible pump which was recently removed after a 90 day interval resulting in an average daily production rate of 13 barrels of oil with 1000 barrels of saltwater. The test pump was removed from the wellbore on May 17thand re-equipped the following day with a permanent 120HP down-hole submersible pump while the company is now awaiting the results of the pump change with the anticipation of achieving 20+ barrels of oil and 1900 barrels of saltwater/day to be disposed in the field disposal well (Quinlan #4).
The Quinlan #3 was tested in the Hunton Limestone and proved to be uneconomical due to a very low oil production rate with heavy water production. The current plan is to re-enter the well around the 1st of June of this year and perforate the Viola limestone in an attempt to replicate the Quinlan #2 production.
The Quinlan #4 was the last well to be drilled in the field with the goal of finding the Hunton Limestone productive. Unfortunately, the down dip Hunton Limestone had incurred a facies change becoming heavily dolomitized with very low crystalline porosity. The 1st Wilcox Sandstone was tested after logs indicated a productive interval with a contradicting sample evaluation. Eventual testing results indicated fresh water had been injected into the zone from an adjacent well without being reported to the proper authorities thus creating anonymous log inferences. The well was completed as a field disposal well in the 1st Wilcox Sandstone which subsequently improved the overall field economics.
Field records reported good oil shows and good production tests from the Viola Limestone and the Simpson Dolomite when tested. These zones should contribute a significant amount of oil when fracture stimulated. There does not appear to be any records of these objectives as having ever been treated.
