Patterson-UTI acquires drill bit provider Ulterra

Patterson-UTI Energy has completed its acquisition of Ulterra Drilling Technologies. The transaction was first announced in July. 

In addition to a growing presence in the dynamic Middle East market, the bit provider also has sales, manufacturing and repair facilities across North and South America and Asia. 

Further, Ulterra’s BitHub data platform complements Patterson-UTI’s PTEN+ data platform. “We believe the combination of data systems from Patterson-UTI, NexTier and Ulterra will create the most comprehensive set of data for drilling and completions in the United States,” said Andy Hendricks, Patterson-UTI CEO. 

Patterson-UTI’s merger with NexTier was announced in June and is expected to close before the end of 2023.

BiSN alloy qualified for P&A, abandonment for Sasol 

BiSN worked with operator Sasol in Mozambique to qualify its Wel-lok tool for rigless P&A and intervention operations. The collaboration involved  deploying the BiSN alloy via perforations in 95/8-in. casing to isolate formation activity from a gas-bearing silt layer and create a suitable regional seal within a 10-m thick shale interval. The project established the viability of the alloy to replace traditional cement.

FET announces partnership with UnderOcean in Brazil

Forum Energy Technologies (FET) appointed UnderOcean to represent its subsea operations in Brazil. The partnership will see UnderOcean provide business development and engineering support on behalf of FET’s Subsea Technologies product line. UnderOcean will also deliver services for FET’s remotely operated vehicles.

Expro’s single shear and seal high-debris 15K ball valve assembly will form part of a full subsea deepwater completion/intervention system for a deepwater subsea field in the Gulf of Mexico.

Expro to deploy shear and seal solution in deepwater GOM field

Expro has secured a contract with a major operator for the first deployment of its single shear and seal high-debris 15K ball valve assembly.

The multifunctional single shear and seal mechanism will form part of a full subsea deepwater completion/intervention system being designed by Expro for a deepwater subsea field at about 6,600 ft (2,000 m) in the Gulf of Mexico.

The mechanism is designed to answer the operator’s requirement for a single-valve subsea solution rather than the conventional double-valve system, while offering the reassurance of risk reduction through an additional safety barrier. 

Expro’s high-debris single ball system, which delivers shear and post-shear seal on a multitude of sizes of coiled tubing, slickline and electrical cable, is a solution for both gas and liquid. It is NACE MR0175 compliant and qualified for sour hydrogen sulfide environments. The mechanism has been qualified to API 17G standard for the performance and design of subsea well intervention equipment.

AGR, Add Energy consolidate services under one brand  

Add Energy and AGR are combining their services in drilling, wells and reservoirs, as well as energy transition technologies such as CCUS and geothermal, under the AGR brand. This move follows the recent acquisition of AGR and Add Energy by ABL Group. Add Energy’s asset integrity management division will not be consolidated into AGR.

Separately, Add Energy was recently awarded funding from the Ocean Energy Safety Institute (OESI) to develop a method to standardize blowout event consequence analysis to support consistent risk measurement of well control events. OESI awards funding for research projects that can improve safety and environmental sustainability of oil and gas operations.


Halliburton’s Obex EcoLock casing annulus packer is designed to deliver isolation assurance independent of losses or circulation pressures.

New packer offers economic option for isolation assurance

Halliburton’s new Obex EcoLock is a compression-set packer that helps to prevent sustained casing pressure. The packer serves as a mechanical barrier to mitigate low-pressure gas or fluid migration and deliver isolation assurance. It can be a cost-effective alternative to inflatable and expandable packers for ensuring isolation assurance independent of losses or circulation pressures. The packer provides V6-rated isolation and can support multiple-stage cementing with optional integral cementing ports and an internal closing sleeve. It is currently available for 7-in. and 9 5/8-in casing designs.

Completions and workover system targets subsea CCS sites

Aquaterra Energy is offering a completions and workover system that specifically supports carbon capture and storage (CCS) developments. Deployable from jackups, semisubmersibles or light-weight intervention vessels, the system will allow operators to safely perform workover and intervention operations in low-temperature and high-pressure CCS subsea sites without concerns of gas leakage.

The patent-pending technology is designed to address issues that can occur when working with stored and pressurized CO2, – for example, sweet corrosion and ultra-low temperatures that standard low-alloy carbon steels cannot safely handle. The solution is based on Aquaterra’s ISO13628-7 completion and workover riser system, which incorporates the company’s proprietary AQC-CW connectors.

Mobile app introduced for real-time frac monitoring

Intelligent Wellhead Systems (IWS) launched the inVision Mobile App for completions operations, which provides real-time access to key wellsite operational data. The app allows users to inspect pad progress and current well activity. When running frac and wireline data through IWS safety and efficiency controls, users can analyze frac and wireline plots remotely.

New safety barrier designed for hazardous applications

Pepperl+Fuchs’ KCD2-SCS-EX2 is a two-channel, dual-function analog input (AI)/analog output (AO) intrinsic safety barrier in a compact 12.5-mm housing. The two channels of the KCD2-SCS series interface modules can be configured individually for AI or AO control signals. They can also function as a power supply for SMART 2-wire transmitters.

For AI signals, the control side can be operated either as a current source or current sink via selectable DIP switches on the front panel.
