SPE Distinguished Lecturer from Welltec visits Iraq

In June, Welltec’s Senior Vice President, MENA, Brian Schwanitz, was invited as part of the SPE Distinguished Lecturer program to give speech at the first formal meeting of the newly formed SPE Kirkuk section. This was the first time a Distinguished Lecturer has ever visited any of the three Iraqi sections and the presentation spurred a great interest. The topic was Intelligent Interventions and as Iraq does not have ready access to coiled tubing units, swift and nimble e-line solutions, like Welltec’s, are exactly what they are looking for.

World’s first nipple milling with 2 1/8” tools

When an operator in the North Sea experienced problems running a 2 1/2” inflatable plug through a Baker “F” nipple profile with an internal diameter (ID) of 2.562” in a producing well, offshore Norway, Welltec proposed a solution utilizing two custom milling bits.

System Integration Testing was conducted to establish operating procedure, determine the suitable bit design and optimum weight on bit (WOB) needed for this world’s first operation.

Two bits, consisting of a unique Metal Matrix Compound (MMC), were manufactured for this specific operation, 2.677” and 2.638” respectively, to grind through the nipple profile leaving the surface smooth to ease further interventions. They were designed so that if the first bit wore down before the nipple was milled through, the second bit could pass through the milled section and finish the job without getting stuck.

No restrictions were found in the well down to the nipple depth and a toolstring consisting of the Well Miller® NPR with the custom 2.677” milling bit was run in hole. After about two hours of effective milling time, the power consumption changed and the tool was returned to surface, where the milling bit did not show significant wear. The toolstring returned into the well with the same bottom hole assembly (BHA) configuration. On this run it passed through the nipple profile without problems. Several more passes were made to confirm depth and easy to pass through.

In a few short days, using only e-line equipment the operator was able to remove the restriction, set a straddle packer and restore the well to production; without the use of a workover rig or CT unit.

Well Completions in focus in Mexico

Welltec participated in the Congreso Mexicano del Petroleo in Cancun this year. The stand featured our new Welltec Annular Barrier – or WAB™ – which is part of our new segment of Completion Solutions. The WAB™ received a lot of attention from the industry, which has a strong demand for flexible, reliable completions that can last the lifespan of the well.

The secret behind the WAB™ is that it offers an elastomer-free, expandable metal packer with great strength designed to deliver flawless zonal isolation or cement assurance in all environments. It even precludes the need for cementing thus enabling truly extended reach wells.

‘World’s first’ cases well received at ICoTA Stavanger

Welltec presented two out of the 11 presentations at the 8th ICoTA Stavanger meeting. Both presentations concerned RLWI operations performed from the Island Constructor in the North Sea, demonstrating our continued success in delivering ‘heavy’ interventions with e-line.

The first of the two presentations concerned a recent clean-out job in which we successfully removed hydrates from a water injection well. When pipe pulse pressure yielded no results, the operator chose Welltec to remediate the problem, as our Well Cleaner RCB was less likely to generate rapid gas release from the hydrate than alternative solutions. The hydrate was present below the subsea tree, but the length was unknown. In less than 20 hours of actual milling time, 173 ft (52 m) of hydrates were removed to a depth that allowed the operator to re-establish functionality to the downhole safety valve. You can read the full case story here.

The second presentation concerned milling through a deep set bridge plug bullnose in a highly deviated well in order to reestablish production from the lower reservoir formation. The plan was to pull the bridge plug to gain access to the screen sections; however due to a restricted ID in the liner, the plug could neither be released nor retrieved. Hence, milling was the only option. Welltec delivered a tailored solution designed to penetrate through the entire bridge plug, and proceeded to mill through the plug’s bullnose without complications.

Three world records in one job

When E&P Yemen needed to log across an 3,087 ft (941 m) challenging, open hole section in an 81.54° deviated water injection well they called on Welltec for a reliable solution that would reach target depth. This operation marked three world records: longest distanced tractored in one job with the 218 Well Tractor, longest distance tractored in an open hole well and longest distance tractored with tandem tractors. An impressive 46,801 ft (14,265.3 m) were tractored during this operation, which was also the first e-line, tractor- based open hole logging job in Yemen.

The well is located in the Kharir Basement in Yemen and was completed in July 2011 to support pressure of neighboring oil producers. It had been injecting water at a rate of ~8,000 BWPD since August 2011 and was experiencing issues with carbonate scale build-ups that had led to decreased injectivity. Due to previous experiences, Total E&P Yemen tasked Welltec with removing the scale bridges prior to the PLT operation and the Well Miller® 218 configured for scale removal milled out 46 ft (14 m) of scale bridges before returning to surface.

The Well Tractor® 218 was selected for the following logging job in a tandem configuration for open hole PLT logging. The Well Tractors were first activated at 9,918 ft (3,023 m) to tractor out of the casing shoe and down to TD. 15 logging passes were conducted. Continuously switching between the two tractors allowed the toolstring to pass through the open hole section despite its challenges and length.

This first horizontal logging operation was of high importance to Total E&P Yemen and proved that there are definite time savings from the e-line conveyance method, due to the fast mobilization, easy rig up / down and the data quality achieved.

Unconventional acid stimulation in the Permian

Recently, an operator in the Permian Basin in Texas engaged Welltec to perform a complicated 18 stage, sliding sleeve, acid stimulation operation in a horizontal well. Our solution was significantly less expensive and much more time efficient than the jointed pipe or coiled tubing alternatives.

This operation required the opening of a number of 4 1/2” sliding sleeves to acid frac through them individually. So open, stimulate, close and move on to open the next sequential sleeve in this 18 stage completion while remaining in the wellbore.

An extensive System Integration Testing proved the capability of the tools and the operation commenced by opening the toe sleeve and then tractoring past it. Acid frac stimulation was done through the opened sleeve while the toolstring remained in the wellbore. Once stimulated, the sleeve was closed and the toolstring moved on to open the next – a procedure which was repeated 17 times more. Before pulling out of hole, all 18 sleeves were re-opened for production.

Because Welltec was able to stay in the wellbore during acid stimulation, the operator saved considerably in terms of time and money. The job was completed in just five days, as compared to ~10 days using coiled tubing or ~20 days with a workover rig.

412 Well Tractor receives praise on Angola job

Welltec was called upon when an operator in Angola needed to perform cement bond logging in a 14” OD casing, offshore Angola. Due to the large casing, our 412 Well Tractor was the only conveyance solution which could accomplish the job on e-line.

A System Integration Test was successfully conducted prior to load out. The toolstring, consisting of the 412 Well Tractor and bond logging tools, was run into the well. At the kick-off point at 9,711 ft. (2,960 m) the Well Tractor was activated and successfully tractored to the total depth at 11,903 ft. (3,628 m). Here the logging tools were activated and data acquired for cement integrity evaluation. Both the Well Tractor 412 and CBL tools worked flawlessly and the operation was accomplished in ~18 hours.

“Please extend my compliments to your team for an excellent job on the bond logging. I was very impressed with their motivation / participation in all aspects of the job from safety to execution. I have great faith in your guys’ abilities after seeing this well and will pass on to our completions guys here,” said Philip Neff, BP Ops Petro physicist, Luanda, Angola.

Welltec India applauded for commitment to safety

During a recent intervention campaign for BG India, Welltec helped to build and maintain the team effort of achieving ‘Safety 101’. This is BG’s internal safety mantra and signifies ‘One Team, One Goal, Zero Injuries’. BG’s program is a good fit with Welltec’s own global safety culture resulting in the program being easily embraced by the Welltec personnel.

Thorough pre-job planning prior, along with continuous monitoring during the campaign laid the groundwork for delivering on the ‘zero injury’ goal. To ensure optimal cooperation between the three participating companies, the campaign was initiated by a team building exercise addressing the HSE Standards, a technical walkthrough of Welltec’s technologies, and creating a joint safety culture. In addition, a successful SIT was conducted in Gandhinagar, including key personnel from BG, Welltec and HLSA and KPIs were assigned based on HSE parameters ensuring that One Team had a single purpose “to safely deliver the plans on time”.

During the campaign, Welltec completed 25,132 man hours of operations along with 34 km of tractoring on a number of platforms with numerous rig-ups, lifts, transfers and jobs. This was accomplished with zero injuries and was applauded by BG India for our commitment to their safety mantra. Welltec was originally selected as a partner for this campaign based on technical capabilities and also for an outstanding global Q and HSE performance.
