Field A is mature hydrocarbon producing field located in east Malaysia discovered in 1963. With multistacked reservoirs more than 7,000 ft high, the reservoirs are predominantly friable and unconsolidated, requiring sand exclusion from the beginning. Most of the wells were completed using internal gravel pack (IGP) methods in the main reservoir. Being an aging producing field, many of the main reservoirs have been depleted and watered out, making the wells inactive. There are, however, several shallower marginal reservoirs, which have been bypassed and undeveloped, known as behind casing opportunity (BCO) reservoirs. The challenge is accessibility to this sand prone reservoir, which might require substantial workover operations, and thus higher costs. Remedial options with proven screen completion can be costly and economically difficult to justify. Mid-2020 marks seven and a half years since the application of a single treatment of epoxy resin in an idle well located in Field A as a remedial approach for BCO. The treatment, proven economically attractive by yielding cost savings of USD 5 million compared to the workover option, further supported by rigorous production monitoring, is unequivocally valuable based on the duration of sustained sand-free production, once again providing reassurance in making this solution a reliable sand-control remedial method for marginal reservoirs. It is important to note that the solution considered a range of laboratory data associated with the chemicals that effectively addressed the requirement based on the characteristics typical of this formation. Well test data from 2013 to 2019 supported sand-free production. Despite experiencing an increment of water cut percentages up to 93.29%, the well is still performing at acceptable production rates. The groundwork processes of candidate identification to the execution of converting the well are described, emphasizing technology comparisons applied in terms of resin fluid system type, execution plan, lessons learned, and best practices developed for maximizing the life of a sand-free producer well.

In this article two dimensional heat equation is solved using finite difference method for the metals such as gold, zinc, tin, marble and bronze. Dirichlet conditions are applied on the boundaries of the rectangular plate. The problem is solved for different metals and the comparison is made for reaching the steady state.

In offshore environment, it is common for operators to develop the field with high deviation wells, in order to optimize both field development cost and reservoir drainage. Well intervention for high deviation wells can be difficult, as specialized tools are needed for well intervention in high deviation wells. As such, high deviation wells normally have well issues after 5 years of production. In Field B, 4 high deviation wells were having unhealthy well lifting, well lifting diagnostics and optimization was needed in order to sustain well and field production. CO2 Tracer Survey was selected for well lifting diagnostics, and all wells were found to have some degree of well lifting issue. With the result from CO2 Tracer Survey, gas lift optimization was conducted, and well was restored to its design condition.

The present study deals with a simple mathematical solution for sharing of discharges at a bifurcation considering simple hydraulic equations like equation of continuity, Chezy's equation, conservation of momentum, etc. Finally, theoretical models for prediction of discharges through the bifurcated channels as a function of radius of curvature, slope, bifurcation angle, velocity of flow, etc. have been developed. A series of physical model studies simulating a typical bifurcation on river Kasai in West Midnapur district in West Bengal have also been conducted on a movable bed model at River Research Institute, Haringhata, West Bengal, India. The theoretical model was found to compare well with recently observed prototype data and physical model test results.
