THE IMPORTANCE OF SOLIDS CONTROL

The importance of solids control is growing with the increasing acceptance of responsibility for minimizing the environmental impact of oil-well drilling. There can be no doubt that the most effective means of reducing the volume of waste generated by the drilling operation is through efficient removal of drilled solids. In deep well drilling, a 10% […]

Integrated Automation for a Mud System

An integrated, automated mud system has combined recent developments to produce an overall package which offers characteristics of safety, environmental acceptability, efficiency, economics, operability and ergonomics. Some of its key sub-components are: Automated monitoring of solids control equipment. Automated addition of mud chemicals. Continuous monitoring of key mud parameters. Automation of mud system valve control and […]

Optimised solids control in arctic environments

Correct use of solids control equipment is critical to maintain drilling fluid within its desired properties with the correct particle size distribution of solids and to avoid generation of unnecessary waste streams during drilling . Since the early 1930s the shale shaker has been the dominating device for primary solids removal. Additional equipment like desilters, […]

Mud Mixing System for Fracturing Sand Slurry

Abstract A new fracturing sand mud (slurry) mixing system has been designed. High sand concentration slurries using a high viscosity non-Newtonian gel can be mixed at low or high rates. A full size mud mixing system was built and tested with fracturing gel and sand. This system includes automatic agitation control, new baffle and mud […]

How flow capacity of a shale shaker was affected

The original plan for experimental study was to determine how flow capacity of a shale shaker was affected by Vibrator frequency and amplitude. Vibrator placement. Angle of the screen with respect to horizontal. Screen size, type, and area. Height above the screen of the fluid weir. Fluid properties. To handle these variables, an experimental vibrating […]

Automatic Shale Shaker Control

Introduction A shale shaker is designed to quickly and efficiently remove solids from mud systems in the presence of changing drilling conditions. Optimal operation typically requires manual shaker adjustments to position the fluid endpoint at ¾ of the screening area, which leaves ¼ of the screening area to dry the cuttings. Sub-optimal operation can lead […]

Shale Shaker Performance

A shale shaker is a vibrating screen used for solid/liquid separation and is the first of several serially connected solids-control devices to process the drilling fluid being from a well. It is a key device in the solids-control system because the efficient operation of other surface solids-separation equipment is critically dependent on proper functioning of […]

Shaker Screen Characterization Through Image Analysis

Description: The labelling of shaker screens has been a problem. Existing mesh count designations do not adequately describe a shaker screen’s potential separation performance. Consequently, it is difficult to make an informed decision when selecting shaker screens. The establishment of a standardized, performance-based designation system has been hindered largely by the time, expense and difficulty […]

Dewatering and Recycling Sump Drilling Mud

INTRODUCTION The dewatering unit (mud recycling unit) was introduced to reduce the high disposal/transportation cost by processing and recycling the sump drilling fluid. A dewatering unit (mud recycling unit) was introduced at MWSS, in an effort to reduce the high disposal cost of sump fluid. Disposal cost for non-hazardous liquid had risen from $10.10/bbl to […]
