Sabiriyah Mauddud is one of the largest carbonate reservoirs in North Kuwait on active water flood since last 20 years using sea water as the injectant. The reservoir is purely a depletion drive reservoir, responding to water flood quickly in terms of increase in reservoir pressure as well as preferential flow of injectant into the nearby producers, thus stressing the existing water handling capacities at the gathering centers. Almost 40% of the injected water re-circulated between the injectors & producers, thus disabling the complete benefit of the ongoing water flood activities. A new initiative has been tried at two of the injectors for cyclic injection for optimal balance between pressure requirements and water cut levels. While water flooding Sabiriyah Mauddud, surprises in terms of rock & fluid understanding influenced quick water cut build up, reaching to more than 90% in some wells. A comprehensive G&G; Reservoir engineering and surveillance data aided to understand the connection factors between the injectors and producers. A fit for purpose tool developed to evaluate the water re-circulation has been used to short list the wells with "bad" water, requiring attention to control. As such bad water had been mainly due to direct short circuiting with the nearby injectors, team decided to go for handling such water from injector management point of view rather than working over the well for conformance related isolation of water producing zone. Cyclic water injection is the best solution so as to minimize the water re-circulation and stay within the operating range of the ESP in the associated producers, with properly spaced cycles of closure & opening. The initiative has been implemented at two of the injectors recently with positive results. The cyclic injection has reduced the water cut at the associated producers up to 30%, thus improving the oil cut significantly. This has reduced the water handling requirements at the gathering centers. The closing action planned for few high water cut wells has been canceled as a result of this strategy. The concept is planned to be implemented in remaining injectors of Mauddud once there are evidences of bad water re-circulation in multiple wells associated with these injectors. Water flood & production efficiency using cyclic water injection approach is a proven way to manage undesirable water encroachment in producers in Sabiriyah Mauddud, the results of which are interesting & worth sharing with the global professionals.

Sabiriyah Mauddud and Upper Burgan are two of the giant reservoirs in North Kuwait(NK) under active water flood since 2000. About 400 MBWPD of water is currently being injected to maintain the reservoir pressure & improve the production/recovery. A comprehensive workflow process was developed and implemented to understand the waterflood performance, pressure-production response trends and map the opportunities to encash the benefits in terms of quick oil gains. The paper discusses the best practices adopted to increase production from two of the water flooded reservoirs in NK. Sound workflow process was created by integrating the technical inputs under collaborative environment from subsurface & surface teams. Series of segment reviews are conducted to understand the connectivity between producers & injectors, duly integrating all surveillance data. Analytical diagnostic tools have been used to distinguish between the good water and bad water and improve the VRR & sweep. Live ESP data is monitored and tracked at intelligent field collaboration centre to decide about the actions for the wells requiring ESP upsizing, downsizing and VSD/choke optimization. Wells with running ESPs were identified for VSD & choke optimization, using rationalized technical criteria. Wells with failed ESPs are reviewed for smart replacements with water shut off/water flood conformance & ESP re-design. Simultaneous actions for the well model creation; running sensitivity and scheduling in the workover rig are taken up. ESP upsize, along with VSD installation/choke optimization, was implemented in number of wells with significant oil gain (about 11% enhancement within a short time frame). As a part of the process established, this activity has become a regular practice in NK. Such wells are under constant monitoring so that water injection actions in nearby injectors, if needed, could be taken up such as allowable management, arresting the declining trend etc. The benefit of mega water flood activities have been reaped in terms of production enhancement adhering to the best reservoir management practices. Quick understanding of the Water flood response and relignment of actions on the associated wells via rigless and rig workovers is the key to the success for significant ramp of the NK production within a short time window of 6-7 months. Several work flow processes established during the campaign are now deeply imbeded within NK asset.

the research aims to evaluate the environmental performance of industrial areas using the Lean and Green portal By reducing waste generated by industries and striking a good balance between operation and environmental performance,. Indicators including labour force (MP), raw materials (Mt), economic cost (Mo), machinery (mc), and the environment have all been researched as ways to accomplish this (mv). The study’s findings revealed that the value of the environment index is just 22%, a very low percentage that denotes neglecting the environmental component in favour of striking a balance among the other factors. The Lean & Green index has a value of 32%. It shows the bad performance compared to the global scale. A number of decisions have been taken in an attempt to improve the performance of industrial regions and achieve balance between different dimensions.

North Kuwait has a vision to produce about 1 million BOPD within next couple of year. As a part of this strategy, all efforts & opportunities are being synchronized to maximize the production. A serious threat to this plan was confronted by observation of Naturally occurring radioactive materials (NORM) at some of the producers, a new challenge for which the asset did not anticipate or had any plan earlier. The paper proposal covers how this threat was converted into an opportunity. A comprehensive review of the wells with NORM was done to understand the link to specific reservoir related issues or zone's mineralogy. As this kind of production problem has been faced for the first time in North Kuwait, brainstorming and technical pros & cons were investigated with internal as well as external consultants. A due diligence was conducted to existing rules & procedures within KOC and Kuwait. Case histories from different parts of the world were reviewed as to how such issues had been resolved. Measurement of NORM, accuracy & validity was also looked into, which varied from vendor to vendor. Thus the gathered knowledge was shared with all stake holder teams. As almost 30-40 MBOPD was the locked in potential, fast track actions have been taken to create a contract to manage wells suffering from NORM. After going through a fast track identification of suitable vendor, contract was awarded to one of the international vendor. Accordingly, workover rigs were made ready to handle NORM remediation operations professionally. Simultaneously, technical evaluation of the performance of wells infected with NORM was done to understand the phenomenon and the relationship with the changes in reservoir pressure / stimulation. A workover schedule was prepared and implemented to revive the shut-in production potential to the GCs, resulting in a bump in oil production for North Kuwait. As a result of the strategy adopted, deferment of oil production due to NORM, which hovered to more than 1.5 years in the past, is prevented, thus helping production target requirements for the Asset. Performance evaluation of wells indicated that there is a strong relationship of reservoir pressure and stimulation with the NORM level. NORM management requires an integrated team approach, ranging from working units to the organization level and a proactive analytical approach to understand the impact of ongoing sub-surface operations on NORM tendencies. The proper understanding and analysis done in overcoming the NORM has aided in enhancing and sustaining the production via having extended productive life for the wells.
