Cementing hardware PetroWiki

Jun 25, 2015· A cementing head is designed to attach to the top joint of well casing during cementing operations. The head allows cementing plugs to be released ahead of and behind the cement slurry to isolate the cement slurry from wellbore fluids ahead of the cement and displacing fluids pumped behind the slurry. Cementing heads may house one, two, or more

Remedial cementing PetroWiki

Jun 25, 2015· Remedial cementing is undertaken to correct issues with the primary cement job of a well. Remedial cementing requires as much technical, engineering, and operational experience, as primary cementing but is often done when wellbore conditions are unknown or out of control, and when wasted rig time and escalating costs have the potential to force poor decisions and high risk.

Cementing equipment Wikipedia

Oil Well Cementing Equipment are essential for the Oil/Gas exploration or production wells and are must used oilfield equipments while drilling a well.. Casing pipe will be installed at various depths while drilling. It is held in place by cement, which also provides zone isolation.Casing is run to protect the wellbore from fluids, pressures and wellbore stability problems.

Temperature Data for Optimizing Cementing Operations

Differences in BHCT and BHST can be quite large (e.g., 40 to 60 degrees F differences are common). Obtaining an accurate measurement of BHCT is especially important because errors on the order of 10 to 20 degrees F can be critical to cement slurry design. During logging operations, temperatures are generally measured by wireline tools.

Rheological Design of Cementing Operations OnePetro

Rheological characteristics of slurries used for cementing should be a major consideration in the trend toward smaller casing sizes, either single or multiple strings. Receiving increased attention is the practice advocated in 1948 by Howard and Clark of attaining turbulent flow with the fluids circulated during a primary cementing operation.

Cementing Operation an overview ScienceDirect Topics

Secondary cementing refers to cementing operations that are intended to use cement in maintaining or improving the operation of the well. There are two general cementing operations that are belonging to secondary cementing, i.e., squeeze cementing and plug cementing. 3.3 Squeeze Cementing. Squeeze cementing is used for the following purposes: •

Equipment Design Change Improves Cementing Operations From

The benefits of traditional inner-string cementing (ISC) methods have not been available to operations in rough seas from floating platforms where the ocean swells exceed the capabilities of the compensators on the rig. As such, new equipment designs are needed to enable use of the inner-string cementing method from MODUs operating in rough seas.

Oil and Gas Well Drilling and Servicing eTool Servicing

Cementing and pumping operations may be performed by specialized pumping services or in conjunction with well servicing operations (such as, casing, squeezing, and zone isolations). The hazards involved will vary with mode of dry cement delivery and mixing as well as the primary designed function of the pumping equipment.
