GEODynamics 是一家射孔、井下完井、干预和绳索输送工具及服务的技术和制造提供商，在最近的 SPE 水力压裂技术会议上发布了两项新技术。 

2 月 1 日至 3 日在德克萨斯州伍德兰兹举行的会议期间，GEODynamics 的战略项目团队讨论了阶段设计挑战，并展示了该公司用于提高水平完井效率的技术和服务。 

数据分析工具准确预测支撑剂和流体流量

GEODynamics 发布了新的StageCoach 数据分析建模工具。经过现场验证的 StageCoach 模型可以准确预测支撑剂和流体如何流过油井，从而显着提高油井产能 10% 至 15%，并且包含在 GEODynamics 的射孔技术中。

行业中的历史假设认为支撑剂和流体均匀地流过井。然而，GEODynamics 利用六家美国运营商进行的地面测试进行的初步研究表明，这是不真实的，并且可能会对油井增产产生负面影响。StageCoach 通过准确模拟支撑剂在集群中的传输、分布和侵蚀来解决这一挑战。这使得操作员在选择孔尺寸和/或装料类型时能够更加深思熟虑，从而使他们能够在没有成本差异的情况下实现假设的分布。它还使运营商具有远见，知道何时何地进行投资以实现回报最大化。

StageCoach 分析包将支撑剂泥浆运动的计算流体动力学模型与全尺寸支撑剂输送表面测试结果集成到工程模型中，该模型可优化作业参数，以确保支撑剂在集群之间的分布更加均匀。由于该模型提供基于事实而不是解释的准确数据，因此压裂设计更加稳健和可靠，从而防止出现可能导致井与井接触的超簇。   

“通过 StageCoach 模型的直接研究和应用，我们获得了令人信服的见解，这有可能显着提高整体压裂设计和油井生产率，”高级技术顾问 Steve Baumgartner 说道。

StageCoach 模型考虑了许多因素，例如泵调度、支撑剂装载、装料选择、射孔间距和定相以及应力阴影，并且它提供了与公司战略项目技术顾问团队的联系。

采用快速连接技术的复合压裂塞可提高效率并节省成本

GEODynamics 还发布了采用快速连接技术的新型 EVOLV 复合压裂塞。新型 EVOLV 堵头消除了许多水平完井挑战，事实证明，电缆公司可以将井场时间节省 95%，即 15 秒，而传统堵头需要 300 秒，从而使运营商能够在油田实现更高的效率。

EVOLV 插头采用新颖的剪切环设计，消除了传统插头所依赖的螺钉，从而消除了性能变量。与使用螺丝时通常需要三到五分钟的安装时间相比，环设计每次都能在 15 秒内可靠、准确地卡入到位。每口井平均有 58 个阶段，使用 EVOLV 堵头可显着节省时间和劳动力。此外，专有的环设计可确保操作员获得充分的设定力，从而消除潜在的泄漏路径、腐蚀和压力损失。

新型全模压复合材料 EVOLV 堵头比其前身减少了 17% 的材料体积且短了 3.5 英寸，从而减少了铣削和钻孔时间，从而缩短了钻机时间。新型 EVOLV 插头的平均铣削时间约为每个插头三到六分钟。此外，较短的长度和复合材料减少了塞子碎片的数量。与传统的堵头不同，EVOLV 堵头可确保井口更清洁，没有金属碎片。

采用快速连接技术的 EVOLV 插头的额定压力为 10,000 psi 和 300 F，与 FracTrap 球输送和回收系统配对，FracTrap 技术使操作员能够自信地将球运行到位。

EVOLV 插头的环形设计旨在通过更简单、更可靠的插头组装来节省运营商和有线公司大量时间并降低潜在风险。操作员可以继续依赖新插头的一致性并利用更可靠的剪切机制。

GEODynamics, a technology and manufacturing provider of perforating, downhole completion, intervention and wireline conveyed tools and services, released two new technologies at the recent SPE Hydraulic Fracturing Technology Conference. 

Throughout the conference, which was held Feb. 1-3 in The Woodlands, Texas, GEODynamics’ strategic projects team discussed stage design challenges as well as demonstrated the company’s technologies and services to improve efficiency for horizontal completions. 

Data analytics tool accurately predicts proppant and fluid flow

GEODynamics has released its new StageCoach data analytics modeling tool. The field-proven StageCoach model accurately predicts how proppant and fluid will flow through wells to measurably improve well productivity by 10% to 15% and is included with GEODynamics’ perforating technologies.

Historical assumptions in the industry have held that proppant and fluid flow uniformly through wells. However, GEODynamics’ primary research utilizing surface tests with six U.S.-based operators demonstrates this is untrue and can negatively impact well stimulation. StageCoach addresses this challenge by accurately modeling proppant transport, distribution and erosion across clusters. This allows operators to be more deliberate when selecting hole size and/or charge type, enabling them to achieve the assumed distribution without cost variances. It also empowers operators with the foresight to know when and where to invest to maximize returns.

The StageCoach analytics package integrates computational fluid dynamics modeling of proppant slurry movement with full-scale proppant transport surface test results into an engineering model that optimizes job parameters to ensure more uniform proppant distribution from cluster to cluster. As the model provides accurate data rooted in facts rather than interpretation, frac designs are more robust and reliable, preventing the superclusters that can cause well-to-well contact.   

“We have gained compelling insights through the direct research and application of the StageCoach model, which have the potential to dramatically improve overall frac design and well productivity,” said Steve Baumgartner, senior technical adviser.

The StageCoach model accounts for a host of factors, such as pump schedules, proppant loading, charge selection, perf spacing and phasing, and stress shadowing, and it provides access to the company's strategic projects team of technical advisers.

Composite frac plug with quick connect technology increases efficiency and cost savings

GEODynamics has also released its new EVOLV composite frac plug with quick connect technology. The new EVOLV plug eliminates many horizontal completions challenges and has been shown to allow wireline firms to improve time savings at the well site by 95%, 15 seconds compared to 300 seconds with conventional plugs, enabling operators to realize greater efficiencies in the oil field.

The EVOLV plug eliminates performance variables by employing a novel shear ring design that eliminates screws, which conventional plugs rely upon. The ring design reliably and accurately clicks into place every time in 15 seconds, compared to the typical three- to five-minute makeup time when using screws. With an average 58 stages per well, the time and labor savings obtained with the EVOLV plug are significant. Additionally, the proprietary ring design ensures operators achieve full setting force, which eliminates potential leak paths, erosion and pressure loss.

The new, fully molded composite EVOLV plug reduces material volume by 17% and is 3.5 inches shorter than its predecessor to decrease mill-out and drilling times for reduced rig time. The average milling time for the new EVOLV plug is approximately three to six minutes per plug. Additionally, the shorter length and composite material lowers the amount of plug debris. Unlike conventional plugs, the EVOLV plug ensures a cleaner well, free of metal fragments.

Rated for 10,000 psi and 300 F, the EVOLV plug with quick connect technology is paired with a FracTrap ball conveyance and retrieval system, and the FracTrap technology enables operators to confidently run ball in place.

The ring design of the EVOLV plug is designed to save operators and wireline firms substantial time and potential risk with an easier, more reliable plug assembly. Operators can continue to rely on the consistency of the new plug and leverage a more reliable shearing mechanism.
