5.9 - Install Annular Materials

Prior to the installation of annular materials the following should be considered:

• Weight of bagged materials (typically 50 - 100 lbs)

• Package shape, bags, pails

• Dust and chemical issues (minimization of dust generation)

• Distance from the staging area or off-load location to the well

Potential Hazards of annular material installation include:

• Silica and other dust (Avoid skin and eye contact; Wear respiratory protection)

• Pressurized lines during grout mixing and placement

• Opening bags

• Knives, box cutters, hammers, screw driver

• Trash obstacles

5.10 - Develop the Well

In most cases, well development activities are performed by a separate rig and crew - not by the drilling rig

and crew. Therefore the development rig crew must consider the same operational safety checks as the

drilling rig. Refer to previous sections of this guide for information about:

• Pre-Mobilization Tasks

• Traveling to Site

• Confirmation Activities

• Preparation and Set Up

• Moving People and Equipment to Site

• Rig Set Up

• Raising the Mast

Prior to well development the following should be considered:

• Methods

• Physical

o Swab

o Bail

o Airlift

o Overpump

• Chemical

o Acid

o Mud thinners (polyphosphates, liganosulfates)

• Fluid containment - drums tanks

o Labeling

o Long term storage

o Hauling
