Mature Fields
A key aspect to manage cementing risks in Mature Fields is to design a program that includes casing equipment that meet the well objectives and challenges. You need to consider cement slurries and casing equipment for challenging wellbore conditions, operational constraints, and regulatory requirements.

Unconventionals
Cementing unconventional wells can present a number of challenges, especially associated with the number and intensity of hydraulic fracturing stages, in extended-reach lateral sections of horizontal wells. Proper selection of casing equipment helps mitigate the risk of inadequate zonal isolation

Deep Water
Deepwater cementing can be challenging due to a number of factors, including narrow pore pressures and fracture gradients, low temperatures, unstable table formations, and salt that can damage wells, causing tight spots, doglegged pipe, or collapsed pipe. Propper casing equipment selection is critical in these environments

- Sub Surface Reales plug sets
Geothermal/HPHT (High Pressure, High-Temperature)
Geothermal cementing faces a number of challenges, including extreme temperature and pressure changes can stress the cement and casing movement. Corrosive gases and naturally occurring brines can cause cement carbonation and steel corrosion. Geothermal casing equipment needs to be corrosion resistant competent in high temperature applications.

Carbon Capture and Storage
Carbon sequestration wells, also known as Class VI wells, are constructed to store carbon dioxide (CO2) underground and prevent it from leaking. Highly regulated well construction and underground injection control standards demand casing equipment compatible with CO2 and resistant to corrosion for the life of the well. Using casing equipment for this challenging environment is critical.
Plug Setting Aids
When it is necessary to plug and abandon a well or to set a kick-off plug, using the right tools to increase the success of plug placement enables safer and more const effective operations.
- Kick-Off Assemblies
Casing While Drilling
In CwD, casing equipment is used for drilling and must endure significant torque and weight applied on it to make hole. A reliable tool for this type of operations is critical to the success of the operation, which includes cementing the casing in place.

Centralization
Proper centralization is a fundamental aspect of a successful cement job. Depending on the type of well construction environment, type of centralizer, quantity and placement are key to a successful primary cement job.
