Generally, reservoir fluid flow is governed by diffusivity equation and solution to this equation helps to investigate pressure behaviour under certain reservoir and wellbore boundary conditions. In this paper however, the analytical solution method of Green and Source function is deployed to determine the performance of a horizontal well located between two parallel sealing faults, assuming simple rectangular reservoir geometry. Also, the dimensionless pressure and derivative approach is applied for all computations as it prevents the problem of unit conversions, reduces longer expressions and it helps to handle numerical values. The pressure expression derived from this work reveals that a maximum of two flow periods occur for the stated reservoir model. It was found out that an inverse relationship exists between dimensionless pressure and dimensionless length while pressure increased with thickness. Also high vertical permeability shortens the effect of the early radial flow period experienced by the horizontal well, thereby increasing productivity index. Finally, it was discovered that increased perforation length reduces the production potential of the horizontal well. Keywords: Dimensionless pressure, pressure derivatives, heterogeneity, pressure performance, reservoir and wellbore characterization.

Bananas are one of horticultural plants with a large production potential in Indonesia. There are two types of bananas in Indonesia, namely that can be eaten immediately and which must be processed first before eaten. Processed bananas are very abundant and one example is a snack called Ledre. One of the Ledre Banana processing industries in Malang City is UD Dua Putri Dewi. The purpose of this study is to find out the marketing strategies used by UD Dua Putri Dewi by using SWOT Analysis as the research method. The results of the analysis show that each factor in the marketing strategy has a varied score. In the strength of the ledre’s banana UD Dua Putri Dewi, the highest score of the indicator score was the delicious ledre banana with a score of 0.189. Weakness factor has the highest score score indicator is the incomplete regulation of the implementation of production and fund management, including SOP (standard of operation and procedure) with a score of 0.121. The opportunity factor (Opportunity) has the highest indicator score, which is very useful government support with a score of 0.206. Threat factor (Threat) has the highest score of the indicator, namely the number of competitors who are increasing and competitive with a score of 0.154. The marketing strategy in UD Dua Putri Dewi using SWOT analysis is in quadrant I which is a strategy that supports aggressive strategies. At that position UD Dua Putri Dewi is in a situation where its strength is taking advantage of opportunities. Thus, the strategy that must be applied in this condition is to support an aggressive growth policy (Growth Oriented Strategy).
