Development And Performance Evaluation Of Novel High-Density Clean Packer And Completion Fluid For Hpht Petroleum Reservoirs

The era of easily producible oil and gas has ended for quite some time, and new oil and gas fields are slowly being discovered in low to high combinations high pressure and high temperature (HPHT) wells. Generally, HPHT wells are classified under a pressure range of 10,000 to 30,000 psia and a temperature range of 350 °F to 500 °F. High density fluid systems have the ability to control the well high pressure for wellbore stability with high density, which contains fewer solids and maintains rheological stability at the HPHT reservoir for minimizing the formation damage and satisfy environmental requirements. This has demanded that new and novel packer and completion fluid designs be developed for low to high combinations HPHT wells. In this paper, developed fluid has shown with high specific gravity and optimum rheology. The calculated apparent viscosity (AV) was found low value which is desired for packer and completion fluid. Our firm belief is that the fluid can be designed optimally for a particular set of requirements specific to aid the completion process with efficient cost, less and high efficiency. From the industrial application point of view, it needs to be free from weight enhancing solid particles.
