“…This causes the gravel to stick to each other and remain still when faced with high oil flow rates. In addition, by fixing the gravel in place, these chemicals prevent the increase of cavities between the gravels and the decrease of the filtration effect. , However, the injection of strengthening materials after placing the gravels in the well has important disadvantages, such as consuming large amounts of chemicals and different distributions of strengthening materials within the gravel pack . Gravels and sands coated with chemicals such as resins, epoxies, phenols, and furans are developed to mitigate this issue.…”

This review aims to bring together the studies on petroleum reservoirs’ sand production control in a comprehensive guide for the researcher to compare various methods for the chemical consolidation of sand. Sand production can be considered one of the major challenges in the petroleum production industry, causing severe operational issues. This study introduces various methods to control and prevent sand production in petroleum wells and evaluates their advantages and performance in tabular form. The use of chemical procedures is considered to be more efficient in counteracting the production and migration of sand. Various chemicals and polymers have been proposed for this purpose. These chemicals should increase the consolidation of the formation rock while not reducing its permeability. The complexity and simplicity of the substances will be the two main factors. Novelties are generally tied with complex chemical structures. Conversely, simplicity makes them affordable, which is essential for industrialization. Success is obtained when the two are combined. This Review is expected to allow individual experts to compare various methods and be a handbook guiding them in the pursuit of finding the appropriate method of sand control for each reservoir.

The Kraken field development was planned and executed through several batch drilling and completion phases to allow a review of each phase and incorporate the lessons learned in the next phase. All producers were drilled with an oil-based reservoir drilling fluid (OB-RDF). The lower completion with shunted sand control screens was installed in conditioned OB-RDF, followed by displacements to water-based fluids after the packer was set. Gravel packing was performed with a visco-elastic surfactant fluid, and a breaker treatment was spotted across the open hole prior to isolating the open hole with a fluid loss control valve. This paper discusses the design, execution and evaluation of the lower completion phase for the development of the Kraken field in the North Sea. This includes detailed reservoir evaluation, methodology followed for sandface completion selection, steps taken to improve efficiency through lessons learned and continuously extend well lengths to be gravel packed in a low frac-window environment, and well performance results in this 24-well field development, with focus on the 7 out of 13 oil producers, detailing 3 of them.

Increasing natural gas demand in Indonesia has driven many operators to develop potential gas field assets, whether offshore or onshore, across Indonesia. One such field is BC which is located offshore East Java in a tectonically active area and part of the ABC complex. The field is composed of carbonate rock which is globigerinid in nature, with the presence of different facies such as packstone, wackstone and grainstone, of which the latter has the best permeability. An extensive geomechanical study was conducted and one of the conclusions was that solids and fines production to some degree are likely to happen from the carbonates in this field. To minimize the risk of solids production, an openhole gravel pack (OHGP) system was designed and deployed. Horizontal OHGP involving screens equipped with shunt tubes for alternate packing are commonly deployed in unconsolidated sandstone formations around the world. The use of filter cake breakers, during or after OHGP placement, is regularly included as part of these treatments. The BC is a carbonate field, besides the low frac gradient and the naturally fissured characteristics associated to the rock which makes it prone to high leak-off, the completion strategy required a special designed filter cake breaker inert to the formation and capable of helping to minimize the lift-off pressure; the challenge required a different approach. The successful completion of these wells required the use of state-of-the art gravel pack placement simulator, special analysis of Bottom Hole data during gravel pack placement and customized gravel pack fluid, capable of transporting proppant and clean the filter cake afterwards. One deviated and three horizontal wells with 9 5/8-inch casing and average of 8.6-inch openhole diameter were drilled and successfully completed. Gravel pack placement interpretation using bottomhole gauge data indicates full annular packing for all OHGP cases. After completion, wells were started smoothly with no solids production observed. This paper highlights key technical challenges and risks encountered during the preparation, design, execution, and evaluation stages of this operation and discusses how these challenges were overcome and the risks mitigated. Finally, the lessons learned and their implementation towards the improvement and optimization of future operations are discussed.
