Fishing Operations in the Well

Fishing Operations are the process of retrieving equipment that becomes stuck or accidentally falls into the wellbore, such as: The following factors must be considered before carrying out a fishing operation: The main causes of fishing operations are: Formations Where Fishing Problems Are Most Common: www.goscoenergy.com Contact Us

Well Completion Essentials Quick Breakdown

Well completion is the engineering backbone that ensures safe and efficient hydrocarbon flow from reservoir to surface. Here is a snapshot of the key components and their functions based on the completion schematic: Safety & Barrier System• Tubing Hanger (1) & SC-SSSV (2): Supports the tubing string and acts as the primary subsurface safety barrier […]

The Installation of A Downhole or Velocity String Using Coiled Tubing

The operation involves running a small-diameter tubing string inside the production tubing to improve well performance, particularly in gas wells experiencing liquid loading.The installation process typically consists of the following stages: Assemble the DWS or Velocity String with the required running equipment, such as:– Running Tool-SDDT (Self-Disconnect Tool)– Centralizers or guiding tools if required Run […]

A Cement Job Is Usually Won or Lost Long Before The Cement Leaves The Truck

The more time I spend in cementing operations,the more I realize that successful well cementing isn’t just about pumping slurry—it’s about understanding everything that happens before,during and after the cement job. Some of the areas that separate average cementers from exceptional ones include: • Understanding laboratory testing—thickening time, fluid loss, free fluid, sedimentation, rheology, static […]

Fishing Operations Recovering What Matters Most

Fishing operations are among the most challenging and technically demanding activities in well intervention. When equipment becomes stuck or lost downhole, every decision matters. Success depends on selecting the right fishing tools, understanding the well conditions, and executing the operation with precision. A well-planned fishing job can: Every successful fishing operation is a combination of […]

What Happens Inside A Three-phase Separator After The Fluid Enters

The performance of a three-phase separator depends not only on its size, but also on the internals designed to control the flow and enhance separation. 🔹 Inlet diverter – reduces inlet momentum and helps initiate phase separation.🔹 Baffles – improve flow distribution and reduce turbulence.🔹 Weirs – help maintain the required liquid levels and interface.🔹 […]

How to Design A Three Phase Separator That Meets Performance Expectations

A well-designed three-phase separator depends on several key factors: ✔ Operating pressure✔ Operating temperature✔ Flow rate (capacity)✔ Fluid properties and composition✔ Residence time✔ Vessel sizing (diameter and length)✔ Oil–water interface control✔ Internal components✔ Proper instrumentation and control system (pressure, level, and interface transmitters, PCV, LCV, and dump valves) Before implementation, Aspen HYSYS can be used […]

Well Control Main Job During Drilling

When Pressure Fights Back, Well Control Takes Over In drilling, pressure is always trying to find a way to the surface. When formation pressure exceeds the hydrostatic pressure of the drilling fluid, every second matters. A rapid, disciplined response can be the difference between a routine operation and a major incident. Well control is built […]

How Best to Rig Up and Manage Solid Control Operations

A properly rigged-up and well-managed solid control system can:Improve drilling efficiency.Reduce mud losses.Extend equipment life.Lower operational costs.Improve safety and environmental compliance. 1.Start with the Right Rig-Up PhilosophyThe goal of rig-up is to create a smooth, uninterrupted flow path for drilling fluid and cuttingsBefore rigging up, ask:Where will the mud return enter?Is gravity working with or […]
