New MWD/LWD service sets field records

A newly launched MWD/LWD service capable of operating in harsh environments up to 392°F and 25,000 psi recently set records in the Haynesville Shale, Sperry Drilling announced.

An operator drilling a long horizontal interval in the Haynesville, an area known for high reservoir temperatures, deployed the Quasar Pulse Service. With temperatures reaching as high as 363°F, the well was completed  with a total depth of 22,595 ft and a total vertical section of 10,072 ft, both field records.

The operator saved an estimated $209,000 by not staging tools into the well and avoiding a potential trip for failure. Additionally, the reservoir interval was nearly twice as long as typical wells in the area, providing higher production and potentially reducing the number of wells needed to develop the field, according to Sperry Drilling, a Halliburton business line.

The new service includes 4 3/4- and 6 3/4-in. tools, allowing it to perform in wellbores up to 9 7/8 in. in diameter. It can deliver directional, gamma ray, PWD and vibration data to enable precise wellbore placement in high-temperature and high-pressure zones.

The service allows access to reserves that conventional tools cannot reach and can eliminate the need for mud chillers and “staging” to cool down tools.

Gravity-deployed carbon composite cable completes first commercial deployment offshore Norway

The Z-line was deployed offshore Norway, where it accessed a platform well to a depth of 9,648 ft, acquiring high-quality fiber-optic data for the operator.

Ziebel, a Stavanger-based provider of specialist well intervention services for the oil and gas industry, announced that its Z-Line gravity-deployed slim carbon composite cable was used to acquire meaningful distributed temperature and distributed acoustic fiber-optic data during a commercial well intervention. The tool made its inaugural run for a major operator offshore Norway.

The system accessed a platform well to a depth of 9,684 ft with standard wireline-type gravity deployment and dry sealing pressure control equipment (no grease injection). All mechanical requirements of the line functioned successfully, and high-quality distributed fiber-optic data was acquired for the operator.

The Z-Line is a 3/16–in. (4.8-mm) diameter carbon composite line with embedded optical fibers at its core. This enables distributed temperature sensing and distributed acoustic sensing to be performed along the full length of the line. In addition, Ziebel’s optical point pressure and temperature sensors are contained within the BHA, along with a connection to enable standard memory logging tools to be run below the BHA. The rig-up and footprint are similar to that of a standard wireline cased-hole setup, although the distributed measurement acquisition method does differ in that it is carried out with the line parked stationary in the well.

The carbon composite material enables the line to have an extremely high strength-to-weight ratio, with a breaking strength (6,600 lb/3,000 kg) in excess of what can be achieved with a similar diameter of steel wire or braided line. The smooth outer finish makes for effective sealing, and the low friction coefficient to steel plus the relative stiffness of the line gives it increased ability to reach into deviated wells. In addition, the low friction reduces the abrasion and tubing wear associated with standard wireline or slickline runs.

Mechanical pipe cutter retrieves stuck tubing in 30-year-old Kuwait well

MPC1Baker Hughes recently used its Mechanical Pipe Cutter (MPC) tool to help an operator in Kuwait retrieve stuck tubing and recover a completion string in a 30-year-old well. By performing multiple cuts in a single operation, the operator saved 24 hours of rig time.

The completion string was stuck due to the accumulation of barite in the annulus between the tubing and the coal seam gas.

Baker Hughes performed multiple 3 1/2-in. tubing cuts in a single operation. Using the 2 1/8-in. MPC tool, six successful cuts were made 300 ft (91 m) apart in four trips within 23 hours. In one trip, the tool performed three cuts, despite tension pull limits from the tubing condition.

1st phase of deepwater GOM seismic survey completed

Schlumberger has completed the acquisition of approximately 2,750 sq km of two new full-azimuth multiclient seismic surveys over the Garden Banks and Green Canyon areas in the Gulf of Mexico. These acquisitions are the initial phase of the Revolution X and Revolution XI surveys and will provide full-azimuth, high-density broadband data.

When completed, the Revolution X and Revolution XI surveys will provide more than 3,800 sq km and 2,940 sq km of 3D data, respectively, for suprasalt and subsalt targets and deeper subsalt Miocene and Wilcox formations.
