Reservoir Stimulation Hydraulic Fracturing
This sheet can be used to perform a complete well model (IPR) for hydraulically fractured oil reservoirs. It can be used to predict the production rate increase after a hydraulic fracture treatment. The sheet also provides: 1. Productivity index (PI) calculations before frac.2. PI calculation post-fracturing.3. Dimensionless fracture conductivity (CFD).4. Negative skin due to Frac.5. The fold of increase (FOI) […]
Progressive Cavity Pump (PCP)
What is a Progressive Cavity Pump (PCP)?A PCP is a positive displacement pump consisting of a helical rotor that rotates within a stator. The interaction between the rotor and stator creates sealed cavities that move fluid progressively from the pump’s intake to its discharge. Key Components of a PCP Working Principle of PCPsThe PCP operates […]
Workover Rigs Overview
With the pass the time the activities of well workover acquire each be important, is not equal drill a well where the economic investment of the project is biggest, where at the same time be need approval of exploration and production permits as well as environmental permits and the complexity that means drill a well […]
Drilling Problems and Solutions
During drilling operations, some type of a drilling problem will almost certainly occur, even in very carefully planned wells. The reason is that geological conditions for two wells that are near each other may differ (nonhomogeneous formation); therefore, different problems can be encountered. The key to success in achieving well objectives is to design drilling […]
Sliding Side Door SSD
In the petroleum industry, a sliding side door (SSD) refers to a type of equipment or mechanism, commonly used in well completion tools, particularly in downhole equipment. SSDs are used during well testing, acidizing, or stimulation to control fluid flow to targeted zones. These mechanisms are crucial in advanced well completions, especially in complex wells […]
Packers and Bridge Plugs
The blades of the underreamer remain inside the tool for accessing throughrestrictions. Then they expand by centrifugal and hydraulic force when pumpingbegins and the downhole motor begins to turn. For recovery, the blades areretracted again by stopping pumping. Common applications for underreaming are cement removal after squeezeoperations and scale removal. When fitted with specially hardened […]
Cementing Calculation
Cementing Calculation Cementing: The Unsung Hero of Oil & Gas Production Cementing might not be the most glamorous aspect of oil and gas drilling, but it’s undeniably crucial. What is it? Cementing involves injecting specialized cement slurries into the wellbore to:Isolate zones: Prevent unwanted fluid flow between different formations.Support the casing: Provide structural integrity and […]

How Long Does It Take to Drill an Oil Well?
Drilling an oil well can take anywhere from 15 days to 12 months, sometimes longer. The amount of time it takes depends on a number of different factors, including the depth of the well and whether it’s on land or offshore. Whether the well is being drilled using vertical or directional drilling also plays a role […]
