DrillScan, société éditrice de logiciel de forage, est une structure en croissance constante et qui, pour continuer de grandir, se développe à l’international. L’amélioration de la situation dans l’industrie de l’Oil & Gas génère de nouvelles opportunités, mais avant d’établir une structure dans un pays donné, il est nécessaire de sonder et d’analyser la situation réelle. Déjà présente en Amérique du Nord par son bureau de Houston, DrillScan a pu, grâce au soutien de la région Auvergne Rhône-Alpes, ouvrir un poste de VIE à Buenos Aires en Novembre 2017.
Dans le cadre de ma mission VIE en Argentine, je suis tenu de rechercher de nouvelles opportunités et d’explorer le marché argentin et plus largement sud-américain, dans lequel DrillScan n’est pas encore implanté physiquement. Avec la découverte récente du grand gisement d’hydrocarbures non-conventionnels de Vaca Muerta, l’Argentine est devenue une terre d’attractivité de premier ordre pour les industriels du pétrole et donc aussi pour DrillScan.
Après plus de 6 mois passés en Argentine, et les rendez-vous effectués sur place, nous sommes donc optimistes au vu des possibilités qui s’offrent à nous sur ce continent et nous espérons initier des contrats qui nous permettront de nous implanter durablement en Argentine et de continuer notre croissance.


Gracias al apoyo de la región Auvergne Rhône-Alpes, DrillScan expande su presencia en el mercado sudamericano.

DrillScan, empresa editora de software para la perforación, es una estructura que busca un desarrollo al internacional para seguir su crecimiento. El mejoramiento de la situación en la industria del Oil&Gas genera nuevas oportunidades, pero antes de establecer una estructura en un cierto país, se necesita sondear y analizar la situación real. Presente en América del Norte con su oficina de Houston, DrillScan consiguió, con la ayuda de la región Auvergne Rhône-Alpes, abrir un puesto de VIE en Buenos Aires a principios de noviembre del 2017.
En cumplimiento de mi misión VIE en Argentina, estoy tenido de buscar nuevas oportunidades y de explorar el mercado argentino y mas ampliamente sur americano, en cual DrillScan no esta implantado físicamente. Con el descubrimiento reciente del gran yacimiento de hidrocarburos no-convencional en Vaca Muerta, Argentina se volvió en una tierra de atractividad de primer nivel para los industriales del petróleo y, por consiguiente, también para DrillScan.
Después de más de 6 meses en Argentina, y de las reuniones organizadas in situ, estamos optimistas con las posibilidades que se ofrecen a nosotros sobre este continente y esperamos iniciar contratos que nos permitirán de implantarnos de manera mas durable en Argentina y así, de seguir nuestro desarrollo.

A Casing Wear Study in HP/HT Well
By: Florent COULIOU

 
Context
High doglegs were present along an accidental nudge interval in vertical section (up to 3.5°/100ft DLS) of the well, resulting in potential critical level of wear along the 14” production casing. The operator’s maximum wear budget for this casing string being 15%.
To minimize the final level of wear along this casing, the operator suggested to run Non- Rotating Protectors (NRPs) within the 12 1⁄4” drill-string along the nudge interval. But some questions were raised: How many NRPs? Where? Will they be efficient?
The NRP provider initially recommended to install 3 protectors per DP. The Operator wanted to challenge this proposal, and before RIH with 12 1⁄4” drilling BHA, DrillScan was asked to:

  1. Assess the impact of the number and position of NRPs on load distribution along the string
  2. Anticipate the levels of wear along the 14” casing for several drillstring configurations

This ERD well in a Deepwater field has reached TD after 22 days. Tens of millions of dollars have been spent already.
Now comes the tricky part: running the lower completion string. This is to connect the wellbore to the reservoir. If something goes wrong, those tens of millions of dollars will have sunk into the deep ocean without a sound.
To make things even more challenging, this reservoir is a shallow burial, which means not much weight is available to push down the lower completion string and the client can face significant risk of lock-up due to buckling.
Something had gone wrong before in one of this client’s other Deepwater fields :
That well was not lost but a side-track had to be drilled and more millions of dollars had to bethrown in to bring the well back on track, not to count the expensive string that was lost in the hole.
Tor que & Drag analysis from the soft string model seems to suggest a trouble – free run to planned target depth even with a ridiculously high friction factor of 0.6 in open-hole. But that’s what it had said last time on that well, too.
It was under these circumstances that DrillScan was called – in to work with the client to ensure a successful run of the lower completion string into the tortuous wellbore. With the p rovided roadmap, and real-time follow-up during the running operations, the string finally reached the planned target depth to client’s relief.

How to get out of a predicament of an unexpected side-track https://www.drillscan.com/rehabilitation-of-a-geothermal-well/ Mon, 12 Feb 2018 10:35:20 +0000 https://www.drillscan.com/?p=10267 A geothermal well doublet producing from a 75°C aquifer, had been operated for over 29 years. The last calliper run performed to control the ID of the 9 5/8” casing indicated there was corrosion and sediments clogging the inner side walls of the injector well, which was hindering production. To regain well integrity, a workover was performed to clean out the 9 5/8” casing in order to reline it. During the workover operations, a cement squeeze-flash occurred causing the 3 ½” drill string being stuck in hole. Remedial operations using coiled tubing was stopped after over two weeks of unsuccessful attempts. The injector well was then suspended with a cement plug set on top of the fish.

Whether it’s in oil & gas or geothermal, an unexpected sidetrack is a costly problem. It’s doubly so when it happens to a producing well, for it not only costs you money to do the sidetrack but also you’re losing production while the sidetrack work is being carried out.

In short, not a happy day for anyone finding himself/herself in such a situation.
However, just as every cloud has a silver lining, there’s also a silver lining in such situations. That is when you have a competent team that can come up with a solid engineering plan and execute with precision and efficiency, your cost for the problem is then minimized and you get back a producing well and you learn a great deal about solving such problems and about correcting issues that caused your problem in the first place.
That’s what happened to one of our clients, whose geothermal well doublet suffered a cement flash-set incident which got the 3 ½” drill string stuck inside casing.
After a series of coiled tubing operations were attempted without success, a painful decision was made to drill a sidetrack in order to restore injection to the geothermal reservoir and save the well doublet.
And there’s one more catch though: the local regulations require proper isolation of all aquifers, which lie below the stucked fish in the hole. That means an interception has to be carried out first to re-enter the original wellbore in order to set cement plugs for compliance before sidetracking the new wellbore.

CFG Services and DrillScan were thus required to propose and plan an Intercept Well level-3 re-entry solution for this client, with objective to :

  1. regain access below the fish, meeting local regulations by properly isolating all aquifers with cement barriers,
  2. restore injection to the geothermal reservoir.

Continuous Inclination Measurements and BHA Modeling Help Detect Microdoglegs https://www.drillscan.com/continuous-inclination-measurements-and-bha-modeling-help-detect-microdoglegs/ Mon, 11 Dec 2017 09:10:11 +0000 https://www.drillscan.com/?p=9979 Microdoglegs are a natural effect of any vertical or directional well that can explain a wide variety of downhole problems. A trajectory-prediction model able to calculate the inclination and azimuth approximately every 12 in. has been developed to estimate microdoglegs using standard surveys, bottomhole-assembly (BHA) data, and steering parameters. This new methodology combining downhole data measurements with drillstring-modeling analysis highlights the potential for drilling optimization and wellbore placement.

This new methodology combining downhole data measurements with drillstring-modeling analysis highlights the potential for drilling optimization and wellbore placement.

Wellbore Trajectory

Standard Surveys. Surveys are generally taken at an interval of every 95 ft, the length of one stand. While the general recommendation is to decrease the survey interval when building faster than 3°/100 ft, this is often neglected because there is no advantage seen in wellbore-positioning-uncertainty models.

The well path between each survey point typically is calculated using the minimum-curvature approach, which assumes a curve of equal angle along the surface of a sphere with only one radius in a 3D plane. Looking at the well as a whole, this approach appears logical and yields reasonable-looking trajectories; however, when examining more-frequent survey data, it becomes obvious how this method can mislead users to think that the well path is much smoother than it actually is. Continuous-survey measurements have enabled the industry to take a closer look at what is happening between survey points, in highlighting microdoglegs quite often undetected by standard surveys.

With the long-term price of a barrel of oil projected to hover around $50, all actors in the oil and gas industry have been forced to change or adapt their processes to try to reduce costs and sustain profitability. Accompanying the downturn, the oil and gas industry has entered a new era of digitalization, introducing new buzzwords to our industry such as artificial intelligence, digital twin, machine learning, neural network, industrial Internet of Things, and cloud computing, just to name a few. The industry has already begun its transition, going from more-­traditional mechanized systems in the hands of humans to more-computer-controlled drilling systems that will eventually lead to full drilling automation…

This video, created from WellScan software, shows a typical case study for unconventional wells. The software simulates the drilling rotary phase along the lateral, where one sees first the vertical phase with no apparent buckling, then the curve with strong side forces and bending stress along the pipe, and at last the lateral section where buckling occurs in a washout section. Note the effect of WOB on buckling, going from 20 to 45klbs. WellScan software is the only commercial software able to run post buckling analysis in 3D wells without using FEA analysis (computation time greatly reduced!).
