There are several operational indicators and trends from the mud engineer’s daily mud checks and a few special tests that can be used to identify water wetting of oil-mud solids before the problem becomes serious and irreversible.Continue reading “Water-Wet Solids In Drilling Mud”
Drilling operations in waters deeper than 3,000 ft are increasing throughout the world, and the industry is considering the challenges imposed by ultradeep waters. Leases have been obtained in water depths up to 10,000 ft, with the requirement that they be drilled within the next decade. Use of current technology to drill these leases will require extremely large floating drilling units and large-diameter marine-riser systems.Continue reading “DUAL-DENSITY MUD SYSTEM FOR DEEPWATER DRILLING OPERATIONS”
The major aim of wastewater management is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment.
Completion and workover fluids are any fluids used in the completion of a well or in a workover operation. These fluids range from low-density gases such as nitrogen to high-density muds and packer fluids. The application and requirements vary for each fluid.
