Managed Pressure Wells

Not Just for Drilling

Building on more than five decades of experience as the industry’s MPD leader, Weatherford, along with our customers, has redefined what you can achieve by managing pressure. With Managed Pressure Wells solutions, you can apply the same field-proven technology to deliver higher quality wells with fewer surprises. By ensuring a stable wellbore, you create a comprehensive pressure management strategy that enhances safety, lowers your well-construction costs, reduces well-control risks, and increases production.

 

Your Well

For decades, Weatherford’s robust portfolio has helped you maintain bottomhole pressure to create a pressure-tight barrier against drilling hazards and manage inflow from the formation during drilling. But managing pressure isn’t just for challenging wells. It is a performance-enhancing solution for numerous well classifications including horizontal, directional, development, and multi-laterals.

By using Managed Pressure Wells solutions as an integral part of your operations, you can maintain wellbore stability by keeping the pressure inside the operating window, avoiding wellbore collapse and formation damage while improving efficiency.

Your Well

Your Operation

Almost every activity within a well alters its pressure. Too low a pressure and you experience kicks, breakouts, and collapse. A pressure too high results in reservoir damage, losses, and slower drilling. Additional wiper trips or hole cleaning runs might be necessary, increasing the overall costs. Under certain circumstances, an influx can lead to a substantial environmental impact, and a surface blowout can result in loss of life, asset, or your company’s reputation.

Striking the right balance is key. With Managed Pressure Wells solutions, every operation contributes to maintaining the safe operating window. By diverting flow away from the rig floor and dynamically altering the pressure inside the annulus, you can drill faster with fewer problems and deliver a more productive well.

Your Operation

Your Environment

Different environments present unique challenges to all drilling operations. Surprises still occur, yet the common methods to manage pressure are either slow (mud changes), passive (modelling), or have an environmental impact (chemicals, logistics, flaring), all of which drive up the overall costs.

Managed Pressure Wells solutions deliver comprehensive pressure management no matter the environment, be it deepwater, shallow water, land-based, or extreme environments.

Your Environment

Better Managed

You already manage the pressure in your well. We provide you with the tools to help you manage pressure even better. Weatherford delivers a trusted approach to all your wells and we continue to innovate and push the industry forward.

Designed to fit any rig floor footprint, our innovative Managed Pressure Wells solutions integrate rig equipment with smart technology for machine-to-machine communication, real-time analysis of downhole conditions, and rapid automated responses from a central location.

Working with industry partners, our technology harnesses the power of advanced algorithms, hydraulic models, and predictive analysis to enable fast identification, decision-making, and reaction to well control events, dramatically reducing the influx size and mitigating risk to people and the environment.

Rudy Flores, Operations Manager, explains how you can create a comprehensive pressure management strategy using Managed Pressure Wells solutions in various operations and not just for drilling.

Cementing

Manage pressure cementing adaptively and precisely controls the annular pressures in the well during cementing operations. It is the process to hold backpressure and managing the cement as it is being displaced.


What are some real results of managed pressure cementing?

By using managed pressure cementing, you can more proactively respond to well events such as gains and losses. Managed pressure cementing is particularly effective in wells with a narrow drilling window, weak formations, or very tight margins.

In one recent example, an operator saved 5 days of drilling, equivalent to $3.5 million, and eliminated the need for a contingency liner.

 
 

What do I need for managed pressure cementing?

Hydraulic models and simulations determine the optimal cement weights for your specific formation and downhole conditions. The managed pressure diverter tool holds surface backpressure and reduces surge while running liners and casings into the well. Based on the field-proven SurgeMaster™ technology, when you deploy the diverter tool, you effectively reduce losses and increase trip speed, maintaining a full-bore inside diameter (ID) through which balls and darts can pass.

What is managed pressure cementing?

Sarah and Trey explain how by managing pressure while cementing, you can reduce losses to your formation, rotate a liner to the bottom, and improve safety by closely monitoring downhole pressures for kicks and losses during the cementing job.

 

Completions

When the tools and techniques developed and used for managing pressure are applied to completions operations, it is possible to easily manipulate pressure while setting completions components, improving efficiency and reducing risks during this phase of a well’s lifecycle.


 

How do you run a gravel pack and manage a stable wellbore?

The conventional method to control wellbore stability included increasing the fluid density, a cost-prohibitive option that would negatively impact the fluid properties and the testing criteria. The MPW solution enabled the customer to adapt to the higher wellbore stability profile with minimum impact to rig operations.

How do you run a completion with a 50-psi window?

The plan called for the operator to run the lower completion, displace the open hole, and perform an acid job. Managed pressure technology provided the solution with the ability to precisely manipulate and manage the annular pressure using a statically underbalanced mud weight within a narrow, 50-psi pressure window.

 

NOT JUST FOR DRILLING

Managing pressure better within a safe operating window can apply to any well and any operation. Weatherford’s Managed Pressure Wells solutions deliver comprehensive pressure management for fewer surprises and higher quality wells, increased wellbore stability, and a more productive well.
