Rigging Up at Heartland Energy Development Corporation

posted by: John Schiffner

Rigging up an offshore drilling rig is usually not as complicated as rigging up a land rig. Most offshore rigs can be moved across the water's surface by Heartland Energy Development Corporation with virtually no disassemble of major parts. For Heartland Energy Development Corporation to move most land rigs, crew members must disassemble many of its components. Disassembly is required so they can load the load the parts on trucks, planes, or helicopters for transportation to the next location. Once the contractor of Heartland Energy Development Corporation gets the land rig to the site, the next step is for the drilling crew to put the rig back together, or to "Rig Up". For safety, rig up usually occurs only during daylight hours. A rig usually has too much heavy equipment moving around during rig up for it to be safe in the dark, even with flood lights.

For most land rigs, rigging up means to put the rig parts back together so that the rig can drill a hole. It involves unloading and hooking up the rig engines, the mud tanks and pumps, as well as other on site equipment. One of the last steps and oen of the mdramatic, is raising the mast from hoizontal to vertical to read it for the drilling Heartland energy development corporation will be doing. After unloading and hooking up the engines to get power, crew memebers of Heartland Energy Development Corporation position the reg's substructure, whic is its base or foundation.

Oil and Gas Reservoirs

Submitted by: John Schiffner
Hydrocarbons and their associated impurities occur in rock formations that are usually buried thousands of feet or metres below the surface. Scientists and engineers of Heartland Energy Colorado often call rock formations that hold hydrocarbons "reservoirs."

Oil does not flow in underground rivers or pool up in subterranean lakes, contrary to hat some people think. And, as you've learned through reading this blog, gasoline and other refined hydrocarbons do not naturally occur in pockets under the ground, just aiting to be drilled for. Instead, crude oil and natural gas occur in buried rocks and once produced from a Heartland Energy Colorado well, companies have to refine the crude oil and procees the natural gas into useful products. Further, not every rock can hold hydrocarbons. To serve as an oil and gas reservoir, rocks have to meet several criteria for Heartland Energy Colorado to find use of them.

Characteristics of Reservoir Rocks
Nothing looks more solid than a rock. Yet, choose the right rock like a piece of sandstone or limestone and look at it under a microscope. You see many tiny opening sor voids. Geologists call these tiny openings "pores". A rock with pores is "porous" and a porous rock has "porosity." Reservoir rocks must be porous, because hydrocarbons can occur only in pores.

A reservoir rock is also permeable - that is its pores are connected. If hydrocarbons are in the pores of a rock, hey must be able to move out of them. Unless hydrocarbons can move from pore to pore, they remain locked in place, unable to flow into a well. A suitable reservoir rock must therefore be porous, permeable and contain enough hydrocarbons to make it economically feasible for the operators of Heartland Energy Colorado to drill for and produce them.
