Abstract

There is growing interest in developing unconventional oil and gas reserves in Libya, such as the tight portions of the Nubian sandstone.

Well-X7 is a development well drilled to a TD of 13,005' penetrating the Upper Nubain Sandstone (UNSS) at 12,122'-12,207' and the Lower Nubain Sandstone (LNSS) at 12,524'-12,880' KB. Based on open hole logs, the UNSS has 71 ft of net pay and the LNSS was found to have 295 ft of net pay. Openhole logs also showed low permeabilities of 2.5 and 3 md for the UNSS and LNSS, respectively. The well was initially perforated in both zones and tested 385 bopd. Hydraulic fracturing is to be applied to this well in the future.

This study evaluated 13 different stimulation treatments for the X-7 well. F300 frac fluid was used with varying proppant type and size, including Ottawa sand, Brady sand and Carbo Lite ceramic. 20-40 Carbo Lite ceramic was used with four different frac fluids, including slickwater. Results for all cases compared IP and 24-month cumulative recovery. Results show that a combination of F300 frac fluid and 20-40 Carbo Lite ceramic proppant give highest production rates. However, cases evaluated had low FCD suggesting conductivity should be increased, and treatment size can be reduced in a final treatment design"--Abstract, page iii.
