Waste Hierarchy (3-R Principle)

Waste hierarchy refers to the 3Rs of reduce, re-use and re-cycle, which classify waste management strategies according to their desirability. The 3Rs are meant to be a hierarchy, in order of importance.

The waste hierarchy has taken many forms over the past decade, but the basic concept has remained the cornerstone of most waste minimizations strategies.

The aim of GVPS in implementing the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste.

Capabilities to implement

 

The 3-R principle

1. Reduction of waste at source

• Drilling with NO Waste Pit

• Zero environmental impact on drilling site

• Safe working environment at the Rig site

• Waste streaming at the rig site

1. a. Requirement for the reduction of wastes

• Strong solid control system on the rig

• Installing a secondary drying system to minimize the service loses

► Solid control equipments:

1. The Shale Shakers 123456

2. Degassers

3. Desander

4. Desilter

5. Mud Cleaners

6. Centrifuges

► Secondary drying system:

1. Derrick Hi”G” Dryer

2. Screw Conveyor

3. Cuttings Collection boxes

4. Liquid collection tank

► Benefits of controlling the waste at source:

• Reduce the oil on cuttings (OOC) < 10% w/w

• Reduce the disposal volume up to 40%

• Reduce the transportation cost of the contaminated waste

• Reduce the mud cost by recovering as much as possible fluid back to the active mud system

• Allows running fine screens on shakers that lead to less solids load on the down stream equip

• Easier handling of dry solids

 

2. Treatment facilities (Recycle)

► GVPS can be responsible for :

1. Solids removal

2. Solids handling and transportations to the treatment area

3. Wastes treatment in our Treatment Plant in new SALHYA

► Liquids treatment:

1. Water base mud treatment (CEC Unit)

2. Oily contaminate mud treatment

► Solids waste treatment:

1. Oil base mud cutting (Thermal plant)

2. Water base mud cutting (Drill cutting solidifications)

 

2. 1. Chemically enhanced centrifugation (CEC) for water base mud

► Benefits of CEC:

• Water – clarified water can be recycled for re-use e.g. rig cleaning, mud or cement make up. Water consumption is thus reduced.

• Pit volume – reduced or in some instances eliminated as water is reclaimed and re-used. Solids hydration is also reduced as liquids and solids are segregated.

• Environmental impact – greatly reduced due to a combination of less water being required to drill the well and less discharge.

• Chemical consumption – minimized due to efficient real time mixing and dosing.

• Mixing – efficient mixing of powdered, granular or micro bead coagulant/flocculent reduces the cost of using expensive pre-mixed solutions.

 

2.2. Drill cuttings solidifications

► Benefits of Drill Cuttings Solidifications:

• Cost – Can be a relatively inexpensive method of treating and disposing of drill cuttings.

• Environmental Impact – Solidification reduces leaching of drill cuttings into surrounding soil to comply with Louisiana State wide Order 29 B.

• Chemical – Other than the inert cement and clay, no chemicals are required that would need post process cleaning.

• Heavy Metals – Stabilization is one of the few methods available for treatment of wastes with leachable metals.

 

2.3. Drill Cuttings Thermal Desorption (Low Temperature Thermal Treatment System)

► Benefits of Drill Cuttings Thermal Desorption:

• Environmental Impact The Scomi Oiltools Thermal Desorption system takes care of your drill cuttings maximizing recycling and minimizing the environmental impact, generating clean cuttings and base oil fit for recycling in drilling fluids.

• Thermal Efficiency The hot oil system offers heat transfer coefficients many times those of alternative thermal technologies. Skin temperatures can be controlled ensuring the base oil remains chemically unaltered. This results in a fuel-efficient system that recycles the base oil whilst minimizing the
