SUMMARY OF RESULTS (MINI-FRAC) 1. Fracure closure ime ( c) was deermined o be 853.9 min.. Fracure closure pressure (P c) was deermined o be 9033 psia a he oe sleeve (D daum = 113.0 fkb-tvd), 10 psia a surface. 3. The insananeous shu-in pressure was deermined o be 11 psia a D daum, 6518 psia a surface, and herefore, he ne fracure pressure was calculaed o be 11 psi. Closure ime was iniially difficul o assess, however, was furher confirmed uilizing oher available echniques.. Fracure gradien was deermined o be 1.009 psi/f. 5. Based on he G-funcion ime (Gc) of 106.5, he fluid efficiency for he waer injecion was deermined o be 98.%. SUMMARY OF RESULTS (AFTER-CLOSURE) 6. The derivaive plo used for afer closure flow regime idenificaion indicaes a ransiion ino a lae-ime rend of approximae -1/ slope signifying linear flow. The presence of pseudo-radial flow was no observed. 7. Alhough pseudo-radial flow was no observed, a lae-ime exrapolaion was conduced on he radial plo o obain a maximum permeabiliy and pressure esimae. In addiion, a lae-ime exrapolaion was also conduced on he linear plo o obain a minimum pressure esimae. Esimaes from he sraigh-line analyses were used as saring parameers for simulaion. The analysis was conduced using a fracure model. Since pseudo-radial flow was no observed, confidence in he resuls is low. However, he esimaed reservoir pressure from simulaion is wihin he pressure range obained. 8. The iniial reservoir pressure of 8698 psia a D daum was obained from simulaion. 9. The flow capaciy (kh) o was also obained from simulaion and was deermined o be 0.111 md-f. The effecive permeabiliy o oil (k o) was herefore esimaed o be 0.007 md, based on a ne pay of 15.0 fee. www.waservices.com (P098) Definiive Opimizaion AER/OGC Requiremens Oil/Gas Opimizaion - Technical Services 300, 80-6 TH Ave SW, Calgary, Albera TP 3E5 Tel: 1 (855) 933-3678 Fax: 1 (03) 79-0055 Websie: www.defop.com
