The study of the causes of changes in the effectiveness of the reservoir pressure maintenance system in terms of the interaction of injection and production wells is an important and insufficiently studied problem, especially in terms of the causes of the attenuation of stable connections between the interacting wells. Based on the results of the calculation of the Spearman pair correlation coefficient, the reasons for the change in the interaction of wells during the flooding process at various stages were estimated. Of particular interest are identified four characteristic interactions, which are determined by the periods of formation of the displacement front.

The Unitary State of the Republic of Indonesia (NKRI) is the largest archipelagic country in the world, two thirds of which are is seas, requiring the presence of the KRI in maintaining its sovereignty. Continuity of attendance in carrying out its main duties, the Navy depends on the readiness of the KRI (Indonesian Republic Warship). The Navy's strength development program is bound to the MEF (Minimum Essencial Force), the basic development policy of TNI AL towards minimum principal strength. The main target of MEF is a limited amount but can operate optimally. So we need a program to overcome these problems by maximizing the defense system maintenance program called SPT (Planned Maintenance System). To maximize the planned maintenance system that supports the MEF program requires prioritization in selecting the KRI that will carry out Depo level improvement (Hardepo). The selection of KRI determination that will implement Hardepo has several factors that need to be considered so that it is categorized in a multi-criteria decision environment, then the proposed model becomes an appropriate methodology to accommodate the criteria with the Fuzzy MCDM (Multi Criteria Decision Maker) approach. In this study there are six alternative KRI namely KRI Keris-624, KRI Rimau Island-726, KRI Kerapu-812, KRI Badau-841, KRI Jakarta Bay-541 and KRI Arun-903 where the first priorities obtained are KRI Rimau Island- 726 with a weight value of 0.1778. After the priority is obtained then schedule the duration and availability of Docking at PT PAL Indonesia where all KRI can carry out docking every TW (Tri Wulan) except KRI Arun-903 which cannot carry out docking on TW I 2019.

The investigated field is located in the Solikamsk drawdown in the northeast of the Perm Territory. The oil content level of this field is composed of Tournaisian-Famennian, Radaevsky, Radaevian, and Tula formations. This article will analysis carbonate deposits from the Tula formation using the multiwell retrospective testing (MRT) technology. Currently, the development system has been already formed, and there is ongoing compaction drilling and targeted drawdown increase that is carried out at certain wells. A pressure support system has been formed. Before the surveys have been conducted, there was a trend in production decline, for reasons that are currently unknown. To identify the causes of production decline at the carbonate reservoir in the field, special technology was used to analysis production history data and bottom hole pressure - this technology is called multiwell retrospective testing (MRT). Four sections were selected for further analysis, MRT was able to reconstruct the reservoir pressure variations and production coefficient at the tested well, the influence of the offset wells on the tested wells has been evaluated, along with transmissibility at the cross-well interval and well-bore skin of the tested wells.

Abstract This paper presents a method for predicting the development of Auto-HF (crack) in injection wells of the reservoir pressure maintenance system during the development of low-permeable reservoirs, in order to ensure the optimal front of oil displacement by water by regulating the bottom-hole pressure of injection wells based on the derived dependence of the half-length of the Auto-HF (crack).

Abstract Today, efficient field development cannot be managed without proper surveillance providing oil companies with important geological and engineering information for prompt decision-making. Once continuous production is achieved, it is necessary to maintain a consistently high level of oil recovery. As a rule, a reservoir pressure maintenance system is extensively implemented for this purpose over the entire area because of decreasing reservoir pressure. At the same time, it is important to adjust the water injection to timely prevent water cut increasing in production wells, while maintaining efficient reservoir pressure compensation across the field. That is why it is necessary to have a relevant inter-well hydrodynamic model as well as to quantify the water injection rate. There are many ways to analyse the efficiency of the reservoir pressure maintenance system, but not all of them yield a positive, and most importantly, a reliable result. It is crucial that extensive zonal production surveillance efforts generate a significant economic effect and the information obtained helps boost oil production. Thus, the main objective of this paper is to identify a method and conduct an effective study to establish the degree of reservoir connectivity and quantify the inter-well parameters of a low permeability tested field.
