Flotek Industries, Inc. has released a study regarding the effectiveness of the company’s suite of Complex nano-Fluid® completion chemistries (CnF®) in the Denver Julesburg Basin (D-J Basin) by MHA Petroleum Consultants, LLC. MHA was retained by the special technical committee established to review the efficacy of CnF® and the company’s data analysis software.

Upon being retained by the technical committee, MHA defined the scope of its evaluation of CnF® performance in three core operating basins: the D-J Basin of Colorado, the Permian Basin and the South Texas Basin (inclusive of the Eagle Ford shale), both in Texas. MHA’s analysis began in the D-J Basin. MHA is continuing to study the efficacy of CnF® in the two Texas basins and the company expects to release the results upon completion of their work.

Highlights of the D-J Basin study protocol include:

• The evaluation of 1,133 wells completed in the Niobrara formation in three focal areas in Weld County, Colorado. The three focal areas were selected because they had the highest density of horizontal Niobrara wells and provided a sampling of wells in both the northern portion (oil prone) and southern portion (gas prone) of the study area. The study focused on Niobrara completions as it is the dominant completion target in the D-J Basin.

• The evaluated wells were identified and mapped to the study area using the “Full Data Download” database from FracFocus. FracFocus is the national hydraulic fracturing chemical registry managed by the Ground Water Protection Council and Interstate Oil and Gas Compact Commission. The site was created to provide the public with access to reported chemicals used for hydraulic fracturing and is used by many states as a means of official state chemical disclosure. FracFocus data is available in two formats: well data available in Format 2.0 provides chemical descriptions in direct data download format and was used by MHA to identify the presence of CnF® in the hydraulic fracture fluid system. Well data provided to FracFocus prior to Format 2.0 were evaluated by downloading individual well data PDF files and reviewed to determine the presence of CnF®.

• MHA applied an additional qualification to its analysis, only considering wells that had a minimum of 12-months of total production. This qualification was intended to ensure that each well evaluated had sufficient production history to accurately quantify the productivity of the well.

• As FracFocus does not contain production data, MHA obtained production data by matching the unique API well identification numbers provided by FracFocus to the commercial well information database provided by IHS Enerdeq Browser. The data analysis was then conducted using application tools such as Excel and Aries, a software tool provided by Landmark Solutions, a subsidiary of Halliburton.

• MHA assessed the productivity performance of the wells (both CnF® and non-CnF wells) using the first 12 months of cumulative oil production and also using an estimated ultimate oil recovery (EUR) over the life of the well. Both of these parameters were calculated in terms of oil volume (barrels) and in terms of the ratio of oil volume to the gross perforated interval length in the horizontal well (barrels per foot). A higher calculated value for any of the four possible parameters indicates greater well productivity.

When analyzing performance using 12-month cumulative oil production, the report states:

“As stated previously, it is the opinion of MHA that the most meaningful comparison parameter in the above three tables is the normalized 12-month cumulative oil volume per foot of gross perforated interval. Using that parameter, the CnF wells in Area 1 showed the most substantial gain in productivity, as compared to the non-CnF wells, with an improvement of 46.9 percent. Area 2 showed the second best performance with the CnF wells showing a 18.3 percent gain over the non-CnF wells. Lastly, Area 3 has the smallest improvement, with the CnF wells showing a 9.8 percent gain over non-CnF wells in this area.”

MHA also studied the relative performance of wells using CnF® in the fracture stimulation process and compared those wells to wells not using CnF® using EUR and states the following:

“Area 1, the most oil prone of the three focus areas, showed the highest gain in ‘EUR per foot of gross perforated interval’ of 58.4 percent with the use of the CnF additive. Area 2 had the next highest gain with 27.6 percent, while Area 3, the most gas prone of the three areas, showed the smallest gain in productivity, 1.4 percent, associated with the use of CnF.”

MHA provided the following conclusions in the report:

“The results presented demonstrate that for Focus Areas 1 and 2, the wells which used the CnF additive showed a significant increase in both 12-month and ultimate oil production productivity parameters. The results for Focus Area 3, which is the most gas prone of the three areas, are not conclusive. Two of the parameters show an increase in the productivity performance for the CnF wells in Area 3, while the other two parameters project the opposite result.”

As noted in the report, “[T]he results presented in this report are considered initial results specific to the areas studied within the Niobrara formation in Weld County, Colorado. MHA is now conducting similar investigations into the effectiveness of the CnF® additive in the Eagleford play area and the Permian Basin of Texas.”

As those studies are completed, it is the company’s intention to release them in a manner similar to the release of the D-J Basin data. In addition, once all of the analysis is complete, Flotek intends to schedule a conference where it will provide a comprehensive review of the methodology and findings to interested parties.
