First Halliburton Female Drilling Fluids Engineer in Pakistan – Asiya Abbasi

“Don’t give up when you are tired and don’t give up when you are done.” My journey at Halliburton began soon after graduating from university. I received a call from Halliburton HR to set up an interview for a preliminary internship with the potential to become a full-time job. I went through multiple interviews and presentations before being hired. I always wanted to join the drilling...

Case Study: Intercept® Retrievable Bridge Plug Provides Reliable Barrier During Blowout Preventer Maintenance Operation

Successful plug performance marks first-ever use of intercept RBP in Azerbaijan and for this operator Challenges – This was a critical well for the customer.  The first branch that  was drilled is currently the longest well in the Caspian Sea, with a total depth of 7,411m.  The second branch, drilled to a TD of 6,803m, would then have to be completed after a period of  BOP...

Tech Paper: Maximizing a Mature Field Value by Combining Polymer Flooding, Well Interventions, and Infill Drilling

Learn how these methods can be properly combined at different stages of asset life The perception of better economics and less risk from infill drilling and recompletions are reasons well-focused remedies are preferred compared to reservoir-focused solutions, such as enhanced oil recovery (EOR). However, most literature does not discuss the economic and risk indicators driving this. Using a real example, this work demonstrates that combining polymer...

Tech Paper: Optimizing Completion Design through Fracture Evaluation in Oil-Based Mud using High-Resolution LWD Ultrasonic Images

Provides real-time data to enhance reservoir understanding and optimize completions Identification and interpretation of fractures, bed boundaries, and borehole breakout from high-resolution images plays a crucial role in optimizing completion design. In low-angle wells drilled with oil-based mud (OBM), images may be acquired using wireline. However, using wireline has been a challenge when inclinations exceed 45°, making logging-while-drilling (LWD) acquisition preferable. This paper presents the first...

Case Study: Halliburton Formation Evaluation (FE) Program Helps Client Discover More than 400 Feet of Net Pay

Safe, Efficient Operations Collected the Required Data in 17 Days Across Two Wellbores Challenges – The customer needed to obtain high-quality formation evaluation, rotary cores, pressures, and fluid samples in two large open holes. The requirements included performing reservoir characterization and rock evaluation for whole-core calibration, and collecting lab-quality samples and accurate reservoir pressures for reservoir quality and structure. Time constraints would need to be optimized...

Case Study: Halliburton Installs World’s First 9 5/8-inch Multibranch Inflow Control System in North Sea

New TAML Level 5 FlexRite® MIC System Enables More Possibilities for Advanced Multilateral Completions Challenge – In March 2017, a Norwegian operator approached Halliburton, needing a new TAML Level 5 multilateral technology (MLT) solution for its mature field in the North Sea. While the operator had been using Halliburton MLT technology successfully for many years in this field, its use was limited to individual branch control...

Tech Paper: Frac-hits Mapped by Tube Waves: A Diagnostic Tool to Complement Microseismic Monitoring

Innovative use of microseismic data to understand direct frac fluid hits at offset wells This paper presents a method for detecting and analyzing tube waves recorded from a downhole geophone array as a hydraulic fracture grows toward and hits the observation well. Examples from both horizontal and vertical monitor wells are presented. An analysis of tube waves provides additional and independent fracture diagnostics data that can...

Tech Paper: The Final Piece of the Puzzle: 3D Inversion of Ultra-Deep Azimuthal Resistivity LWD Data

3D earth models reveal a reservoir’s true structures, allowing for informed geosteering decisions and accurate well placement Optimal well placement requires three-dimensional (3D) spatial knowledge of the reservoir formation and fluids. Current one-dimensional (1D) inversions of ultra-deep azimuthal resistivity logging-while-drilling (LWD) data recover formation boundaries above and below the wellbore, which are stitched together to form pseudo-2D models (or “curtain plots”) along the wellbore. However, 1D...

Case Study: Innovative Elect® Frac Sleeve System Proves Successful for Demanding Well Conditions

‘First of a Kind’ Sleeve System Enables Complex Completions and Minimizes Risk Challenges – Rockcliff Energy was interested in a frac sleeve system without operational pressure limitations to allow for higher circulating and cementing rates, and to help eliminate the risk associated with wellbore packoff and the inadvertent shearing of pins. A further limitation with conventional toe valves is determining an ideal pinning configuration that resists...

Tech Paper: Improved Completion Economics Through Real-time, Fiber Optic Stimulation Monitoring

Successfully installed single fiber-optic equipped well provides useful feedback on completion designs This paper demonstrates how a single permanent fiber installation allowed the development of improved completions designs in real time in order to improve well economics. Design changes were adjusted during the completion of the well to determine stage length and completion execution. Improvements were applied to the subsequent wells in the program. In 2018,...
