DrawWorks external grip assembly provides higher hoisting and torque capacity that you need for those deeper and longer wells. Today our blog will look into how our modular external casing running tool will make it much easier for your oilfield work. The design is modular to adapt to the base head assembly so it can easily replace the internal gripping assembly. The change from internal to external takes approximately 90 minutes. This allows your casing crews to be ready for whatever the field is requiring without the need for additional tools sitting idle in inventory. Make plans to contact us today to learn more or to get a demonstration on the DWCRT.

No Need for a Cementing Head Anymore

Why use a cementing head when our casing running tool is available? Regulations ensure a proper cement job in today’s wells. A conventional cementing head does not allow rotation of the string. The well is properly put in with cement by rotating and reciprocating the string. Traditionally this has been done by a rotating cement head.

These tools are often large and require extra NPT (non-productive time) to be rigged up. By using the same casing running tool to run the casing and cement the well, this eliminates the need for rig up time. Due to the high-pressure requirements of cementing, we provide high-pressure packer cup options rated up to 10,000 psi. There is also a modular circulator assembly to allow a secondary packer cup to be put in after the casing is run just before cementing. This gives the operator a secure feeling that there will be no leaks during the cementing process.

Cost-Effective Case Running Tools by DrawWorks

Did you know that casing running tools and a cement swivel rather than a cementing head will provide a mechanized, safe and cost-effective way to run and cement casing? We manufacture casing running tools for both onshore and offshore drilling rigs. We design and manufacture products that are strong and safe. Typically, the conventional drilling process involves drilling, tripping drill pipe out of the hole and then casing the well. This new process uses a standard casing string when drilling.

Drilling and casing the well are done simultaneously. This eliminates tripping and isolates formations while drilling. The Casing While Drilling process brings many benefits to drilling operations, especially on wells experiencing problems. We manufacture the best casing running tools and cement swivels for the job which eliminates the use for a cementing head. Drilling these types of wells conventionally can be challenging. This process is beneficial when it comes to surface or conductor casings.

Casing While Drilling Operations

During Casing While Drilling operations, the pipe is in constant contact with the wellbore. This smears the cuttings. In combination with certain types of lithology, this works together to close and seal leaking formations. Fluid loss can be a thing of the past at this point. The casing running tools replace the need for a cementing head for the final step in this process

Casing While Drilling along pay zones has also been accumulated, especially in depleted reservoirs where skin damage is a concern. If this takes place along low-pressure productive sandstones, the process offers the possibility to drill variable pressure zones with less fluid invasion. Skin damage is greatly reduced. There is no other better replacement for a cementing head than our line of casing running tools combined with our cement swivel. This is another reason to trust the professionals we have on staff.
