Porosity Porosity is the fraction of the total volume of the rock that is pore (non rock) space or void and not made of solid pieces of the formation. It will be filled with a gas, water or hydrocarbon or two or more at the same time. Porosity will range from a high […]
Drilling Muds A water-base drilling fluid is one that has water as its continuous or liquid phase. The types of drilling fluids are briefly described in the following lines. Freshwater muds are generally lightly treated or untreated muds having a liquid phase of water, containing small concentrations of salt, and having a pH […]
Types of Casing Based on the primary function of the casing string, there are five types of casing to be distinguished. Stove or Surface Casing The stovepipe is usually driven to sufficient depth (15–60 ft) to protect loose surface formation and to enable circulation of the drilling fluid. This pipe is sometimes cemented […]
Each drilling fluid vendor provides a wide array of basic and specialty chemicals to meet the needs of the drilling industry. The general classification of drilling fluid additives below is based on the definitions of the International Association of Drilling Contractors (IADC): Alkalinity or pH control additives are products designed to control […]
Fishing Operations and Equipment A fish is a part of the drill string that separates from the upper remaining portion of the drill string while the drill string is in the well. This can result from the drill string failing mechanically, or from the lower portion of the drill string becoming stuck or otherwise becoming […]

Chemicals Used in Fracturing The identities of chemicals incorporated in fracturing fluids were probably the first thing sensationalized about fracturing. The movie “Gasland” created quite a stir with the statement that a “cocktail” of several hundred toxic chemicals were “potentially” used in fracturing. The grain of truth was that there are many chemicals in additives […]
Rotating system: the figure indicate the comparative sizes of the drill pipe and drill collar. Swivel ♦ The swivel hangs from the drilling hook by means of large bail, or handle. The swivel is not rotate, but allow everything below it to rotate. ♦ Drilling fluid is introduced into the drill stem […]
Drilling Mud Tests The field tests for rheology, mud density, and gel strength are accomplished in the same manner as outlined for water-based drilling mud. The main difference is that rheology is tested at a specific temperature, usually 120◦F or 150◦F. Because oils tend to thin with temperature, heating fluid is required and should be reported on the […]
Drilling Fluids To properly control the hole cleaning, suspension, and filtration properties of a drilling fluid, testing of the fluid properties is done on a daily basis. Most tests are conducted at the rig site, and procedures are set forth in the API RPB13B. Testing of water-based fluids and nonaqueous fluids can be similar, but variations of […]
How to plan for an Oil Well? Drilling optimization requires detailed engineering in all aspects of oil well planning, drilling implementation, and post-run evaluation Effective well planning optimizes the boundaries, concstraints, learning, nonproductive time, and limits and uses new technologies as well as tried and true methods. Use of decision support packages, which document the reasoning behind the decision-making, is […]
